1.3 PROCEDURE OF INSTALLATION
The crane arrives complete with supports for
installation and screws. The first step is lift the
crane from the load eyes appropriately installed to
avoid the damage to people or goods during the
installation of the crane.
1. Position the pedestal in the location pre‐

arranged for the installation.
2. Weld the pedestal along the whole contour
ANTIROTATION BLOCK
To weld antirotation block
to the pedestal.
(See paragraph 1.3 page 11)
3. Connect the basement to the slewing ring taking care that the antirotation block and the
rotating distributor will couple correctly (2) (if the antirotation block is not installed see
paragraph 1.3 page 11).
4. To screw the basement bolts, should turn the same basement up to intercept the head of the
pin from the hole(1) located near the reduction gear.
5. This is necessary to restore the hydraulic connection with the rotating distributor(if they were
disconnected) and turn the lever that controls the rotation.
6. Tighten the bolts M30 10.9 with a torque as report in the Page 10, by a dynamometric key.

WWW.SORMEC.NET

The bolt connection is crucial to the slew bearing function and life. A proper fastening of the slew
bearing is required by relevant calculation. This calculation determines the quantity and preload
force of the fastening bolts.
Proper preload is met with:
1. High precision torque wrench
2. Hydraulic tensioning equipment
3. length measure on calibrated bolts

The torque is affected by: bolt quality and grade thread connection friction and friction between the
contact surfaces of bolt head, nut and parts themselves.
The bolts must be carefully tightened crosswise to the specified preload.
WWW.SORMEC.NET

The tightening torque MA to pre‐load FM, for a medium friction value of μG ≈ μK = 0.14, is indicated in
the following table.

Dry threads require higher tightening torques, heavily oiled threads require lower tightening torques.
It is absolutely necessary to tighten the bolts to the required preload. It is to be ensured that the
necessary bolt torque data are maintained over the whole time of operation. We recommend to
check the torque after 3 month of operation and than after 1 year.
NOTE: In no case securing elements such as loch and spring washers may be used. Only the
preloading force of the bolt serves to secure the bolt.
WARNING!Tighten the bolts M30 10.9 of the slewing ring with a torque 1890 N.m
for hydraulic torque wrench.

2 CRANE DESCRIPTION
2.1 INDICATIONS OF THE CRANE MODEL
At one side of the crane column, in a visible position, a
manufacturing‐plate will be attached, indicating all necessary details
for the identification of the crane.
Herebeside, a manufacturing plate fac‐simile is shown.
2.2 IDENTIFICATION OF THE MAIN COMPONENTS
A sketch of the crane is shown here below, from which all crane components can be identified:

1 Basement 9 Second Extension
2 Crane Column 10 Third Extension
3 Operator Cabin 11 Upper Sheave block
4 Boom 12 Lower Sheave block
5 First Extension Cylinder 13 Winch
6 Second Extension Cylinder 14 Motoreduction Gear
7 Third Extension Cylinder 15 Cylinders Boom
8 First Extension 16 Slewing Ring
WWW.SORMEC.NET

2.3 CRANE SORMEC
Sormec marine cranes are equipped with hand operated hydraulic control valves. Each control handle
corresponds to a given motion. When released it returns back to its “neutral” position, thus stopping
the crane motion.
By manoeuvring the handle mildly, the crane will work smoothly and without any sudden
acceleration.
Cranes booms and hydraulic extensions are driven by double acting hydraulic cylinders.
The rotation of the crane is executed by a toothed crown and a pinion system in which:
 The pinion is operated by an oleodinamic reduction gear which is integral with the boom
foot.
 The toothed crown is made up of a slewing ring bearing with ball/rolling where the
external crown is integral with the boom foot, the internal section is integral with the
pedestal and is complete of the toothed crown coupled with pinion.
All cranes motions are protected by pilot operated counterbalance valves which automatically
prevent slippage and load drop in case of pipe failure or burst hoses.

7 CRANE USE
7.1 RECOMMENDATIONS FOR THE USE
 When starting up the crane, especially in cold weather, it is advisable to carry out some
manoeuvres without load in order to reach the correct fluidity inside the hydraulic circuit and
verify the regular crane working. When working with the crane, once the control handle is at its
end stroke, release the handle immediately to avoid unnecessary oil overheating.
 Avoid any sudden stop of the crane movements when the
load is hanging on. Because this, during the lowering
manoeuvres mainly, may damage and unnecessarily
stress the crane.
 Avoid sudden and abrupt manoeuvres. Operate the

control levers smoothly and gradually.
 Operate the crane control levers following the

instructions shown on the knob labels.
 Never drag loads along the deck or the ground, but slew
them raised from deck or ground.
 Place the crane exactly above the cargo to lift in order to
avoid pulling on the vessel deck or on the ground.
 In case of welding to be carried out on pieces suspended
by the crane hook: never use the crane hook, never use
the crane structure as the weld earth path.
 Make sure that the loads lifted, in relation to the
outreaches, do not exceed the load chart ratings.

WWW.SORMEC.NET

 The crane load chart must be carefully respected especially in case the manoeuvre to be executed is that to
lift a load close to the crane and move it far away. Never trust on the intervention of the overpressure
valves, which might be unset or out of order if not constantly inspected.

 Crane must be properly maintained so as to overcome possible periodical inspections made by the
Inspection Bodies.
WWW.SORMEC.NET

7.2 CRANE OPERATION
Before using the crane it is recommend to make the following controls:
 Check Or (Verify) that are no oil leaks on the fittings of the hydraulic circuit;
 Check the wear of the hook;
 Check the safety latch of the hook and the wear of the hook;
 Check hydraulic oil level.

After making the following controls you can start using the crane by the following steps:
 Check if all emergency push buttons are unblocked;
 Go to the HPU BOX control panel below deck;
 Turn on the main disconnector switch (1) shown in position;
 Turn on the auxiliary 01 interruptor(2)shown in position 1;
 Press the Start push button HPU+Running monitor light(3);
 Press the footswitch(4) to move the crane.

WWW.SORMEC.NET

7.3 STOWING POSITION
The cylinders rods must be as much protected as possible. The hydraulic extensions should be re‐
entered as much as possible at the end of the working day. It is necessary to stow the crane at very
low speed, making sure that no damage or impact occur between the crane itself and its hoisting
accessories.
In order to make it easier for the operator we recommend to lock the hoisting hook on a fastener and
to tension the winch wire rope.
7.4 TURN OFF THE CRANE
To shut of the crane safely follow the following steps:
 Put the crane in rest position;
 Press the stop HPU+ Fault push button (1) monitor light;
 Go to the HPU box control panel;
 Deactivate the auxiliary 01 interruptor(3) shown in position 0;
 Deactivate the main disconnector switch(4) shown in position 0.

WWW.SORMEC.NET

7.5 EMEGENCY POWER PACK
The hydraulic power pack is equipped with an auxiliary electric motor instead of the main electric
motor in case of failure.
WARNING: the auxiliary electric motor should only be used in case of emergency in order to put
the load to ground and put the crane in rest position. Never use the auxiliary emergency power
unit for lifting loads, this could cause damage or injury.

Activate aux electric motor

To activate the auxiliary electric motor follow these
procedures:
 Check if the main disconnector switch (1) is always turn ON;
Deactivate aux electric motor
 Check if all emergency push buttons are unblocked;

7.6 END STROKE DEVICE
The supply of a winch can also include the supply of an automatic end
stroke device both for upward and downward wire rope control.
The intervention of the end of stroke device immediately stops the crane’s
operations, avoid to use the end stroke device voluntarily, especially with
the maximum load hanged on; this would imply useless stresses to the
crane structure.
7.7 USE OF THE WINCH
Avoid to use the winch if the load hook stands on the ground. The
inconvenients involved by hoisting the load hook from ground should be an irregular overlap of the
wire rope or the running out of the rope from the drum.
Before starting to hoist the load, move the crane winch at empty hook. This operation is extremely
important especially when the crane and the winch have been stored for several days. The empty
hook operations allow a proper of control of the winch function and guarantee the oil filling inside
the winch brake.
When the outside temperature is rather low (+5°/ ‐20° C) the above operations have to be carried out
for several minutes before starting the ordinary work with the winch.

9 MAINTENANCE
9.1 MAINTENANCE RECOMMENDATIONS
These maintenance planning identify:
a. Deficiencies which could reduce the capability and operational safety of the crane.
b. Actions required to correct deficiencies to maintain good operational capability
It is envisaged that this Recommended Practice will assist Operators in development of their own
Inspection and Maintenance schedules according to their specific equipment and its location and
operational use. Where established Inspection and Maintenance schedules are in place, the
Operator may use this Recommended Practice to support or complement such schedules as
appropriate. It is expected that the crane and its elements, particularly those of high utilization such
as prime mover, gearboxes, pumps, motors etc. would be maintained on the basis of condition. The
frequency of Inspection and levels of Maintenance stated in this Recommended Practice are for
guidance only.
9.2 REGULAR INSPECTION
For cranes in regular service, the inspection intervals are dependent upon the nature of the cranes
components or systems and of the degree of their exposure to wear, deterioration or malfunction
and of the consequences to operational safety. Two inspection categories have been assigned herein
'frequent' and 'periodic'
a. Frequent inspection ‐ visual daily to monthly intervals
b. Periodic inspection ‐ at stated intervals which shall include daily and monthly inspection.
9.3 ANNUAL INSPECTION
Each crane shall be inspected fully every 12 months by a qualified inspector, whereby all remedial
work will be identified and cleared prior to issue of an inspection certificate. Annual inspection
shall include regular inspection schedules.
9.4 DEFICIENCIES ARISING FROM INSPECTION
a. All deficiencies arising from inspections shall be carefully examined for impairing safe
operation. In such instances the crane shall be taken out of service or its operation limited to
remove the unsafe condition 'CAUTION' notices shall be positioned at the control cabin and at
the prime mover as appropriate.
b. Where cranes have been subjected to major repair or modification to either structural
members or to the main functional services, the cranes shall be thoroughly inspected and
function/load tested by a qualified inspector.
WWW.SORMEC.NET

9.5 INSPECTION RECORDS
Inspection details which include reports as well as records of repairs and modifications carried out
on the cranes shall be dated and signed for monthly, quarterly and annual inspection. These
records shall be kept readily available by the operator.
9.6 CRANES NOT IN REGULAR USE
Cranes which have been idle for a period of one month up to six months, shall be inspected according
to the periodic requirements of Regular Inspection.

WWW.SORMEC.NET

9.7 ROPES
Crane ropes used for luff and load hoist systems, are often spooled onto their drums in multiple
layers and, as such, they need to be tolerant to crushing and abrasion. The load hoist rope will usually
be of non‐rotating, multi‐strand construction. Both rope types should incorporate an independent
wire core with all wires in the construction galvanised. Galvanising gives added protection to the rope
when in store whilst enhancing its fatigue life in operation.

WIRES BREAK WIRES BREAK
(BREAKAGES DUE TO FATIGUE (BREAKAGES DUE TO EXCESSIVE
STRENGTH) TENSILE STRESS)
THE WIRE ROPE IS DEFORMED IN SUCH

REPEATED TEARING STRESSES CAN
A WAY THAT THE INTERNAL SIDE IS
CAUSE WIRES RUN OUT OF THE ROPE
VISIBLE OR RUST IS APPEARING
Where non‐rotating rope is used, the following should be noted:
a. Failure of non‐rotating rope can occur suddenly and without apparent warning and is usually
initiated by breakages of the inner wires of the construction. Total failure could therefore
occur without showing any visible indication at the outer wires Evidence of one broken
external wire, is a strong indicator that the rope may already have several broken internal
wires and could therefore be close to total failure.
b. Loss or drying‐out of the lubricant accelerates corrosion and fatigue of the internal wires Such
conditions will promote early failure of the rope. Close proximity of gas turbine exhausts and
flare radiation effects in addition to a saline environment, will serve to exacerbate the
problem.
The following practices should be observed:
The outer and inner wires of the rope should be inspected for any visible breaks. The internal
wires should be examined by twist‐opening the strands with rope grips or lever clamps. For non‐
rotating rope constructions, the ropes should be discarded if broken wires are found and /or
corrosion is evident. For the rope, use discard criteria according to national regulations. Example:
WWW.SORMEC.NET

a. Ropes should be lubricated with a penetrative lubricant‐ oil with viscosity of 30 SAE is
recommended. The lubricant should be applied by pressure lubricator. It is essential that the
lubricant penetrates the inner wires particularly on non‐rotating ropes. Never use viscous
(thick/heavy) lubricants on wire rope, these create a harmful 'barrier' effect leading to
corrosion and rapid failure of the internal wires.
b. Rope change‐out (according to rope condition or prevailing statutory requirements) should be
undertaken only in accordance with the crane/rope manufacturers procedures. Where
provided, dedicated spooling or rope change‐ out drums should always be used.
c. Pendant ropes should be inspected and lubricated as for running ropes with particular
attention paid to the condition of the wires local to the entry point at the terminations. With
the application of good lubrication/inspection procedures pendant rope can be expected to
remain in service for 3/5 years.
d. Other ropes on the crane, which are not in the primary load path but which have important
functions such as, safety harness wires, boom handrail wires, boom back stop support wires,
constant tension wires (e.g., supporting temperature sensors in the luff system) etc. should
be checked as part of the drivers daily routine, with a more thorough examination every three
months.
e. All rope terminations and anchor points should be examined on the same frequency as wire
ropes.
9.8 ROPES MAINTENANCE PLANNING
 Daily – Monthly
a. Check rope is spooling evenly on drums without loss of pattern and without undue gapping.
b. Check rope for condition ‐ abrasion, particularly at flanges and cross‐over points; crushing,
usually due to slackly spooled rope corrosion, signs of rust; loss of lubricant, particularly on
active sections e.g., continued use around sheaves; broken wires.
c. Check rope for other abnormalities, e.g., spiralling, basketing etc.
d. Check terminations for condition and security
e. Check levels of lubrication at the rope and its terminations
 Monthly ‐ 3 Monthly
Lubricate ropes using a penetrative lubricant with viscosity of 30 SAE by a pressure lubricator. For
sections of rope which are difficult to access, such as 'dead lengths' and terminations, lubricate by
hand.
 3 Monthly ‐ 12 Monthly
Inspect the internal wires of the rope for corrosion, broken wires and lubricant quality. Use the
WWW.SORMEC.NET

correct tools ‐ twist‐grips and procedures as specified by the rope manufacturer only for this
operation.
 Change‐Out
According to rope condition and/or discard assessment .
a. Check that the replacement rope is the correct size (diameter and length) and construction.
Ensure these details are as specified by the crane manufacturer.
b. Check that the test certificate clearly identifies with the rope and that the rope taken from
store was on a 'first in', 'first out' basis.
c. Only use change‐out practices specified by the rope/crane manufacturer.
d. Ensure new rope is not dragged over the ground/deck or fouls obstacles or any part of the
crane structure when spooling onto the winch drums. Where possible use dedicated rope
spooling gear.
e. Check that 'turn' is not induced during spooling.
f. Ensure all terminations are compatible with the rope
9.9 WINCH DRUMS MAINTENANCE PLANNING
 Daily ‐ Monthly
a. Check drum flanges and kicker strip if fitted, for undue rope scrubbing or heavy wear.
b. Check drum flanges for spreading or splaying.
c. Check drum mountings for general condition and security.
d. Check condition of all external lubrication/environmental seals.
e. Check brake drums/discs for scoring or uneven wear.
f. Check for condition and security of rope termination clamps at drum flanges
 Monthly ‐ 6 Monthly
a. Check all major fasteners associated with the drum against the manufacturers
recommended. Typically and where applicable, such fasteners would be:
i. Main drum unit foundation bolts
ii. Bolted/screwed‐on drum flanges
iii. Bolted/screwed‐on back stops or brake drums/discs.
iv. Bolted/screwed‐on back stops or spragg clutches
v. Bolted/screwed‐on ratchet (boom hoist drum only)
b. Check condition and securement of final drive gear/chain pinions/wheels.
c. Visually check for 'cracks' at all main weld areas on drum and drive mounting; this may be
indicated initially by local paint cracking.
WWW.SORMEC.NET

 After 1000 hours of winch operation (with average operating cycles at 60%
nominal load) a full service of the negative brake is mandatory. This work must be done by
the Producer.
9.10 HOOK AND HOOK BLOCKS
a. Check safety catch functions correctly without hang‐up.
b. Check that hook swivels smoothly and that by 'feel' there are no signs of bearing 'catch' or
brinnelling.
c. Check hook for increased admittance dimension, undue flattening (burring) 'nicks' and cracks.
d. Check that all split pins securing hook swivel nut and rope guards are intact.
e. Ensure rope anchor points are in good order and properly secured.
f. Visually check that all sheave and hook shank bearing seals are sound.
g. Ensure all rope guards are secure and are set at correct clearances from Sheaves.
h. Check sheave tread profiles for undue wear and damage.
i. Ensure all lubricant channels (grease points) are clear, undamaged and provide free flow of
lubricant.
9.11 SLEWRING BEARING AND FASTENERS
 Monthly to 6 Monthly
a. Check the tension in four bolts (one in each quadrant) at slewring to pedestal and slewring to
crane according to crane manufacturers procedures.
b. Check bolt tension in any associated retaining device.
c. Check that the main bearing environmental seals are in good condition. Renew immediately if
damaged or distorted.
d. Check final drive slew gear teeth for undue wear ‐ tearing and plucking.
e. Ensure pinion drive has full face width contact and correct pitch line setting ‐ check backlash.
f. Ensure all guards are in place, correctly fitted and secure.
g. Check rocking clearances.
h. Ensure all lubrication points are undamaged and provide free flow of lubricant.
 6 Months to 12 Months
a. Remove at least one fastener from each mounting circle and examine for corrosion and stress
corrosion cracking. Renew rather than replace the bolt.
b. Check lubricant for water content and particle content.
WWW.SORMEC.NET

9.12 WIRE ROPE REEVES
Check the sheaves, the transmission pulleys, the head pulleys very often. The structure must not
show any deformation deriving from crashes/collisions and the structural strength must not be
compromised by the corrosion.
Pay particular attention to the pulley slewing motion which must not show excessive clearance, pay
attention to the rope side walls which must not show any deformation, crack or breakage.
The pulley slew on a support which needs to be periodically greased: this will increase the life of the
bearings and decrease the slewing friction of the pulley itself.

WWW.SORMEC.NET

9.13 WIRE ROPE CHANGING
If the wire rope needs o be changed is necessary to respect all the features of the old wire rope
installed on the crane. We recommend to contact Sormec after sales department in order to receive
the correct information and instructions. In any chase the replacement needs to be carried out by
qualified people.
9.14 ELECTRIC MOTORS
a. Ensure all guards are secure and correctly fitted
b. Check all locally mounted gauges/instruments are functioning
c. Check for condition, security and chaffing of locally run electrical cables
d. Check for correct function of local start/stop and emergency stop controls
e. Check for securement and performance of ancillary equipment i.e., compressors etc.
9.15 HYDRAULIC OIL‐FILTER CLEANING
For proper crane functioning, use hydraulic oil of HLP type, ISO
viscosity, to be selected according to the outside temperature as
per table below:
-15 °C ÷ 0 °C VG 15
0 °C ÷ +40 °C VG 46

For proper crane functioning, a filter must be installed on the electro‐hydraulic power pack. The
return line filter between the control valves block and the oil tank is 30 microns.
The filter must be cleaned after 8 working hours and subsequently every 50 working hours.
WWW.SORMEC.NET

The cartridges must be washed with solvents and air sprayed.
The filter body must show no impurities and no cracks.
If this occurs it is necessary to replace the cartridge with another one having similar features.
It is advisable to replace all filter cartridges at any oil change
9.16 CHANGE OF HYDRAULIC OIL
To assure the best working in the time, check the oil and replace it periodically. We recommend this
operation after the first 100 working hours and then after every 2000 working hours or at least once
every year.
The hydraulic oil has to be replaced with the same make or with similar one.
To change the hydraulic oil please refer to the following operations:
A) Close the crane cylinders completely. Make sure that the oil coming out from the return pipe
fitted to the upper filter doesn’t flow into the tank: this oil is dirty;
B) empty the oil tank removing the tap (see num. 3);
C) Remove the oil left in the tank;
D) change the oil filter as indicated in the picture below (see num. 1 )
E) fill the tank from the tap with new hydraulic oil(see num. 2);
F) Fill in the oil tank with clean oil, up to the correct level.

9.17 LUBRICATION
The articulation’s pins and the extensions need a periodic lubrication. Such intervals of greasing the
articulation pins vary in relationship to the use and the particular type of crane. In the underlying
chart are show the periods of greasing recommended.
Inject fat in pressure until it doesn't escape from the coupled elements so that to replace the old
lubricant. After the lubrication, perform some complete movements of all the articulations of the
crane and add some fat to guarantee an optimal lubrication.
WWW.SORMEC.NET

Clean the hydraulic extensions from the impurities. Keep the sliding pod well greasing, cover the
external inferior side and the external superior side from the telescopic arm with grease. To make
sure that all the points of greasing are always well lubricated, using the type of suitable grease on the
chart. Other greases having the same characteristics can be used.

9.18 CONTROL VALVES BLOCK
For the control of the crane motions, all Sormec marine cranes are equipped with hydraulic control
valves block, of a proportional type. Each element is protected by two auxiliary valves: one on the
suction line and one on the return line.
The complete block is also protected by a main check valve (main valve). Operate the crane controls
following the instructions placed on each knob.
When the selected lever is released, it returns automatically to the neutral position and it stops the
motion. Operate the lever smoothly and gradually to avoid abrupt movements. Sormec crane control
banks may allow (if requested) several movements to be carried out simultaneously. When
maintenance on the crane is carried out, verify that the handles automatically return to their neutral
position, oil the pins on which the handle turns, if necessary.
Verify that no leak appears.
In case it is necessary to dismantle the control block elements of crane, when re‐assembling the
whole, pay particular attention to the tightening of the fixing bolts.

11 SAFETY PRECAUTION
We believe that a paragraph of this handbook should be dedicated to the accessories which can be
installed to the crane’s hook for lifting the load. The experience has taught us that unintentional
accidents represent a minimum percentage compared to those caused by neglection or non‐
compliance with the basic safety norms. Carelessness can cause damages to properties or even worse
injuries to people. We always recommend to verify, periodically, the integrity of the wire ropes and
belts using for lifting the loads. When selecting their diameters please consider the additional stress
they are subject to when not used in vertical position.
11.1 WORKING AT HOOK
Before handling the load, make sure it is balanced by lifting it a few centimetres only. Never store the
ropes in wet areas and never expose them to excessive heat.
Never use chains connected with screw bolts.
The incorrect application of the rope to the hook can open the
hook safety latch. The safety latch must always return to its
original seat after the ropes have been attached.
11.2 WOKING AT WINCH
When the use of the crane depends on the winch, the operator
must be much more careful during ordinary operations with the
crane; most of the accidents depend on the sheave block or load
pendulum effect or by accidental breakage of the wire rope.
Here below are some recommendations which should be carefully
respected in order to operate with the crane safely and to improve
its efficiency in the long run.
11.3 NUMBER OF WIRE ROPE REEVES
The number of original wire rope reeves supplied by Sormec
cannot be modified, for any reason, by the customer or third
parties.

11.8 LOAD HOISTING
The load hoisting from the ground must be executed through the winch.
If the load is topped by the crane main topping cylinder, the load will
immediately move sideways with a dangerous oscillation. This
oscillation will increase proportionally to the increase of the boom
vertical position. In other words is very important to lift the cargo using
the winch using the boom crane as support.
11.9 LOAD APPLICATION
We highly recommend to always verify the integrity of the wire rope
and belts in relation to the load to be hoisted up. When selecting the
proper wire rope or belt diameters, please take into account superior
strength the rope and belt have to stand when not working in vertical
position.
Before hoisting the load from ground, please verify if the load is
balanced by lifting it up by some centimetres. Never use chains connected with screw bolts.
11.10 HOOK SAFETY LATCH
The hoisted load must be hanged to the hook making sure that the latch is completely closed. The
application of wire ropes or chains in such a quantity that
the latch cannot be closed, determinates a reduction of
the safety performances as well as danger that the wire
rope can run out of the hook with consequent load
crash.
11.11 OPERATIONAL PERFORMANCES
1. It is absolutely forbidden to hang to the wire
rope a load heavier than the winch hoisting capacity and trying to handle the load topping with
the crane. The winch and all accessories would then be subject to an overstress which could
involve the breakage or the damage of some of the components.
2. It is absolutely forbidden to hoist with the winch a load heavier than the crane lifting
performances, the crane should then be subject to an over stresses which could involve the
breakage or the damage of some of the components.
3. The maximum load at hook cannot exceed the maximum crane lifting capacity or the maximum
winch hoisting capacity.

WWW.SORMEC.NET

12 SAFETY NORMS
12.1 SAFETY CONTROLS
Before manoeuvring the crane, make sure that the hook and omega are perfectly efficient.
Make sure that the lifted loads, in relation to the outreaches, do not exceed those stated on the
diagram.
Please remember that the load diagram gives maximum lifting capacities and in case of
supplementary equipments (such as grabs, power blocks, supplementary hooks etc.) it is necessary to
deduce the weight of the accessories from the rated loads.

Never walk under an overhanging load and never

stand in the crane operating area. Never tamper
with the crane hydraulic circuit. Please make sure
that nobody stands or walks in the crane operating
area.

It is Strictly forbidden to hoist (with the winch) higher loads than the ones given on the load diagram.

In case the crane’s operator, from this operating spot, cannot see the load to be handled, a
communication with another operator is then necessary.
For that purpose the following system of clear visual signals is advisable:
Should the operator not clearly understand the signals, the crane must not be activated. The operator and the
signalman can decide, before starting any loading operation, to use a different communication system.

13 TROUBLE SHOOTING
The following chapter reports some of the incovenients which might occur to the crane and the
pertinent solutions Warning: in case of an inconvenient to the crane, never work on the hydraulic
settings without the specific knowledge that such an action will solve the problem.
FAULT CAUSE SOLUTION/REMEDY

Noisy pump Low oil quantity inside the pump Verify the oil level (the crane must
be folded), if necessary bring the oil
inside the power pack to the right
level
Dirty suction line filter the oil cannot Dismount the filter, clean it or replace
flow through it if worn (see instructions given on
the handbook)
Worn pump Verify the pump features. Compare
the maximum pressure value shown
on the gauge meter and the topping
time of the main boom cylinder to the
specific cranes data (see technical
sheet referred to the crane hydraulic
connections)
The pump support is loosen Verify the screw tightening which
connect the pump to the electric
motor
The bleeder vent inside the oil tank is Verify that no piece of material or
plugged other things are left on the bleeder
vent inside the oil tank
The crane move jerks Low oil quantity inside the oil tank Verify the oil level (the crane must be
folded), if necessary fill in additional
oil which must have the same
features (see handbook)
Worn pump Verify the pump features. Compare
the maximum pressure value shown
on the gauge meter and the topping
time of the main boom cylinder to the
specific crane data (see technical
data sheet relative to the crane’s
hydraulic connections)
The crane doesn’t lift the rated loads The geometrical indications relative to Carefully read the handbook, chapter
the proper crane configuration are not “Directions for use of the crane”
respected
Insufficient pressure inside the crane Compare the maximum pressure
hydraulic circuit value shown on the gauge meter with
the specific crane data
Control handle doesn’t return to the Lack of lubricant on the handle Remove the inferior support of the
central seat linkage control handle and the cap placed i
the opposite side of the control
handle, Clean carefully and grease..
Damage/breakage to the handle Remove the cap mounted to the
spring opposite side of the control handle.
Replace the spring, reference is
shown on the spare parts of book

The crane slewing doesn’t stop when Inefficient piloted block valve Replace the block valve with another
the relative control handle returns to one having similar properties and
its central seat setting values
One crane motion is slow The control valve handle doesn’t Verify that the handles fixing screws
complete its stroke are not loosen. Verify that the rod
return spring is opposite the control
handle, on the control valves block tip
The crane boom lowers when lifting Worn cylinder seal Identify the cylinder which moves in
rated loads under loading. Replace the seal
Replace the piloted block valve with

another one same setting values

It’s impossible to inject grease from a Broken greaser Replace the greaser, the code for
greaser order placing is shown on the spare
parts book
Dismount the pin and remove the set

grease. Inject new grease
The injected grease set
Oil leakage from one hydraulic The connection is loosen Tighten the connection following the
connection instructions given on the handbook to
see the right torque wrench
A fittings has been damaged Replace the fitting: place the order
giving the code number shown on the
spare parts book
Oil leakage from the bottom side of Worn slewing cylinders seals Dismount the slewing cylinders and
the crane base replace the gaskets
The crane has a winch with No electric supply to the system By means of a tester verify the
electro-hydraulic end stroke right inlet tension in the crane
device: no crane motion is electric circuit
allowed
Broken electric cable Verify the integrity of the electric
cables and micro-switches
Jammed oil return electro valve At the boom of the electro valve
there is a socket screw. Loose
the counter nut and tighten the
socket screw. In such a way the
electro valve shuts mechanically.
WARNING: with the electro valve
off, the end stroke device does
not work any longer, therefore
such an operation must be done
only in emergency cases
The crane slewing doesn’t stop when Inefficient piloted block valve Replace the block valve with another
the relative control handle returns to one having similar properties and
its central seat setting values
