General
The power is supplied by the two variable motors to the power control box and transferred to the drilling
tool through drive socket. The crowd winch system can make the rotary drive slide up and down along
the mast to fulfill drilling. The lubricating oil in the power control box ensures that gears and gear rings
are always in best lubricating and cooling.
1.3.2.2 Derricking mechanism (4-bar mechanism)
The derricking mechanism is mainly composed of boom, pull rod, tripod and derricking cylinder. The
front articulated point of the tripod and the articulated point on the two-stage derricking cylinder are both
connected with the mast to supply oil to the two two-stage derricking cylinders (mast lifting cylinders)
simultaneously or separately so as to control the laying and erection of the mast. The mast is always
kept vertical to the horizontal plane in the operation in case of the working surface with a gradient less
than 2°. The distance between the kelly bar center and the rotating center of the slewing platform can be
adjusted flexibly in operation by controlling the length of one-stage derricking cylinder (permissible
derricking range is 3905~4800 mm).

5 Operation
Before the drilling rig starts rotary drilling, check carefully the tightening torques of the
fixed bolts for all the coupling pins and shafts, and the lubrication oil (grease)
filling conditions at all lubrication points. Pay attention to the lubrication oil
quantities of the hydraulic oil tank, traveling reducer, reducers of main winch and
auxiliary winch, rotary drive box body, reducer and slewing platform's reducer.
Notice Check the fastening bolts (screws) of all the reducers timely and screw them all.
Moreover, check the liquid levels of the engine system's coolant and the oil sump's
engine oil, and check whether the slewing bearings of the slewing platform and
kelly bar have sufficient lubrication grease. Only when the drilling rig is ensured to
meet the using requirements after the above-mentioned check and adjustment can the
engine be started.
In order to prevent the starting elements from being damaged, the starting engine
should not be operated for more than 10 seconds each time. If the engine cannot be
started in two consecutive times, turn the key switch back to the OFF position, wait for 2
minutes and then start it again. After a starting failure, if the engine is started
repeatedly, or if the waiting time to turn the key switch again is too short, the starting
Caution engine will be damaged.
If the complete drilling rig is equipped with outrigger cylinder, when it needs to operate
the outrigger cylinder, switch button No. 22 in Fig 4-4 to the crawler position and switch
button No. 16 in the same figure to the outrigger cylinder position first. Then operate
joystick No. 1 in Fig. 4-6, and the extension and retraction of the outrigger cylinder can
be achieved. When it needs to operate the crawler, switch both button No. 22 and button
Notice No. 16 in Fig. 4-4 to the crawler position, and then operate joystick No. 1 in Fig.4-6.

Operation
(2) Once the mast center is within the range of 3905-4800 mm, turn No. 20 in Fig. 4-4 back to the
non-working position immediately.
5.3 Slewing Platform
When the drilling rig is working, the slewing operation of slewing platform is frequent. Its steps are as
follows:
(1) First, press the horn button (No. 18 in Fig. 4-4) to sound the horn.
(2) Press down the slewing protection button on the joystick of the left control box and pull the joystick
outwards. Then the slewing platform can turn anticlockwise (leftwards); pull the joystick inwards,
and then the slewing platform turns rightwards. During this operation, if button D has not been
pressed, or if this button and the wiring are faulty, the platform will remain static. (No. 2 in Fig. 4-5)
5.4 Mast
One of the basic conditions for drilling rig's rotary drilling construction is that the mast must be raised and
basically perpendicular to the ground. The following steps raise the mast or lay it flat:
(1) The mast raising joystick (see No. 3 in Fig. 4-5) on the left control box is provided for raising or
lowering the mast. Pull the joystick forward and the mast is raised; pull the joystick backward and
the mast is laid flat.
(2) During practical operation of the mast, it will lean leftward/rightward due to various reasons. If the
mast leans, adjust it at all times according to the data displayed dynamically on the display. If the
mast leans leftward during the raising operation, pull the joystick forward. Meanwhile, adjust the
joystick's inclination angle inward properly to reduce the mast's leftward inclination. If the mast leans
rightward, adjust the joystick's inclination angle on the opposite side. Perform these steps until the
mast is raised as required by the operation. If the mast is inclined when it is being lowered, the same
steps are applicable.
(3) If the mast is inclined during construction, operate the joystick on a single direction
(forward/backward or leftward/rightward), and the perpendicularity deviation on a certain direction
(X or Y) can be rectified in time.

Operation
5-6
Operation
(1) Turn switch No. 22 in Fig. 4-4 to the "Rotary drive" position (see Fig.
5-8).
(2) Operate the pilot joystick on the right operation box inward (see No. 1
in Fig. 4-6), and positive rotation of the rotary drive (rotary drilling of
the drilling tool) will be achieved.
(3) If you want the rotary drive to rotate fast to increase the drilling tool's Fig. 5-8 Control switch of
drilling speed, carry out the abovementioned operation, and press the rotary drive
button I on the top of the joystick at the same time.
(1) When the rotary drive drives the kelly bar normally, turn switch
No. 11 in Fig. 4-4 to the "Pull-down" position (see Fig. 5-9).
(2) Operate the pilot joystick of the right operation box forward
(see No. 1 in Fig. 4-6), and then the pull-down cylinder can be
extended (to press the rotary drive down). If an interlocking
kelly bar is used, during the extension of the cylinder, the
internal-teeth insert plate of the rotary drive will come into the
boosting groove of the kelly bar automatically from a proper
Fig. 5-9 Control switch of the
position. Then the pull-down will be more effective.
pull-down cylinder
(3) If you want the piston rod of this cylinder to extend quickly, carry out the abovementioned operation
and press down button J on the top of the joystick at the same time.
5.7.2 Retraction
Stop the rotary drive and reverse it properly. The retraction operation process is similar to that of 5.7.1,
but the operation direction of pilot joystick No. 1 in Fig. 4-6 is opposite (pull this joystick backward). If an
interlocking kelly bar is used, in order to retract the cylinder, stop the rotary drive and make it reverse
before the operation. Make sure the rotary drive's pull-down button is completely pulled out of the
boosting groove of the kelly bar.
5-7
Operation
The whole operation process should be carried out slowly and orderly. Observe carefully and
assume unified command.
Notice!
(1) Since the operator's view is limited, he/she cannot see everything outside. There
must be a signalman who cooperates with the operator to move the equipment on
Warning the work site.
(2) The route and site for moving equipment should be free and unimpeded.
(3) The site should be level and solid. Soft places should be covered by some hard
materials such as wood.
(4) It is forbidden to drive or turn the drilling rig laterally on any slope.
(5) When the drilling rig passes a road section with slopes head-on (slope ≤ 15°), the
mast should be retracted as in transportation state.
(6) During the whole transferring operation of the drilling rig, the slewing platform is not
allowed to be slewed; sudden starting and sudden stopping should be avoided.

10-6
Maintenance
Check if the slewing tie-in can rotate freely without the load, for
example, rotate the tie-in manually.
If the tie-in still can not freely rotate, repair or replace it.
For the safety purposes, replace the parts with the ones of same
specification.
When filling the lubricating grease, check if the upper and lower axle
pins of tie-in are installed correctly (upper one is connected with the
steel wire rope and the lower one is connected with the kelly bar).
If the gap is too large or the axle pin, bolt, etc. are damaged, replace them.
10-7
Maintenance
Check the rotary drive assembly appearance for damage, as well as the bolt and axle pin for
looseness.
The magnetic catch-all on the rotary drive is magnetic. Check the catch-all every 100 working hours,
and clean the iron filings of gear. If you find an increase of iron filings or clay, stop the work to open
the power case. Handle it timely to reduce the damage to a minimum.
10.7.2 Checking the Level of Rotary Drive Box
Check if the front mast is vertical.
Power case is equipped with an oil observe window, with the oil pointer to always observe the level.
Check the oil level inside the power case.
The oil level inside the power case shall always be at center-top position of oil pointer!
When the oil inside the power case gets muddy or the water penetrates into the
case, replace the power case immediately: rinse the case repeatedly with the clean
oil before the filling!
Caution
10.7.3 Changing the Oil of Rotary Drive Box
Precautions:
For the new equipment, after 250 working hours, change the gear oil of rotary drive; change it every
1000 working hours or every year, whichever comes first.
The grade of gear oil shall be (room temperature) Meropa 220 gear oil or (cold area) Meropa
Synthetic EP 220 gear oil. When changing the new-grade gear oil, test the compatibility of the oils.
It is better to change the oil after the rotary drive begins to rotate and the temperature is constant. If
the outdoor temperature is low during the oil change, we recommend it to heat a certain amount of
new oil (50 °C) to clean the rotary drive in order to flush out the remaining impurities and minerals in
the rotary drive.
If the working temperature of rotary drive exceeds 100 °C, the discharged oil would darken or
blacken, aggravating the wear of lubricating oil and depriving it of the lubrication function. In this
case, the oil change interval shall be correspondingly shortened.
Check the oil for impurities and minerals (abrasives). The maximum permissible residual oil
accounts for 0.15% of total oil.
The largest size of particle in the lubricating oil shall not be more than 5μm. If so, whatever amount,
be sure to move the rotary drive and carefully analyze.
Rinse the rotary drive with the benzene or flushing oil other than the gasoline, oil or diesel.
Inject the new oil after the flushing oil inside the rotary drive is completely discharged.
Warning!
