The Demag DRS 112 to 200 wheel block system, suitable for loads up to
10000 kg, is a concept designed to meet customer wishes.
The advantages of the system are:

• Most favourable ground clearance conditions with Demag offset geared motors.
• Robust aluminium housing with very good shape and position tolerances.
• Variable basic design by fitting various travel wheel materials and shapes.
• Weather-resistant due to surface powder coating (RAL 7001, silver grey). Spe-
cial paint finish available on request.
• Compensation of track gauge deviations of up to 3 mm per side possible.
• Protected internal bearing arrangement.
• Minimum maintenance due to bearings lubricated for life.
• Travel wheel and bearings can be replaced thanks to bolted housing.
• High installation availability since the housing with top connection does not nec-
essarily need to be removed to replace the travel wheel. Not having to realign
the housing saves time.
• The damping element in the travel wheel reduces the load on the gearbox.
• The gearbox output torque is transmitted to the wheel block virtually without any
radial force by means of the special Demag torque bracket.
• High-tensile bolted connections are zinc-coated and therefore provided with
long-term corrosion protection.

The Demag DRS 250 to 500 wheel block system, suitable for loads up
to 40000 kg, is designed as a heavy-duty travel unit based on the same principle
as the smaller DRS 112 to 200 series.
The advantages of the system are:

• Most favourable ground clearance conditions with Demag offset geared motors.
• A robust spheroidal graphite cast iron housing with precisely machined connect-
ing surfaces.
• Variable basic design by fitting various travel wheel materials and shapes.
• Possible compensation of track gauge deviations up to 4 mm or skewing up to
14 ‰.
• Protected internal bearing arrangement featuring tapered-roller bearings.
• Minimum maintenance due to bearings lubricated for life with standard ambient
conditions.
• The friction bearing arrangement is prepared for re-lubrication in the case of
special ambient conditions and re-lubrication sets can be simply added later on.
• Travel wheel and bearings can be replaced thanks to bolted housing.
• High installation availability since the housing with top connection does not nec-
essarily need to be removed to replace the travel wheel. Not having to realign
the housing saves time.
• The torque bracket, designed to match the wheel block, reduces peak loads
and enables the drive torque to be transmitted virtually without any radial force.
• High-tensile bolted connections are zinc-coated and therefore provided with
long-term corrosion protection.

1.7 Travel wheel materials
EN-GJS-700-2 (GGG 70) GJS-700-2 (GGG 70) is a spheroidal graphite cast iron, a material with a self-lubri-
cating effect owing to the graphite incorporated in it. Therefore, the travel wheels
feature high wear resistance with low travel resistance, thus minimising wear on
the rail. The high inherent shock-absorbing effect of the travel wheels ensures
smooth travel characteristics of the travel unit. Travel wheels with guide features,
e.g. flange-guided, with a tread distance to the travel rail of min. 1 mm and guide
roller arrangement with identical distance are available.
Hardened travel wheels For operating conditions in which increased travel wheel wear is likely (e.g. rails
with extreme dirt accumulation by casting sand or similar), the treads and flanges
of the spheroidal graphite cast iron travel wheels are specially hardened, see sec-
tion 4.9.6.
Travel wheels with Hydropur tyre Hydropur is a polyurethane elastomer which features good resistance to hydro-
lyses compared to other conventional polyurethanes (such as Vulkollan, for ex-
ample). This material features significantly higher friction values compared to GJS
(GGG) wheels, thus making travel wheels with a Hydropur tyre predestined for
highly dynamic applications. Running noises are reduced to a minimum owing to
the good dampening characteristics. Attention must be paid to the considerably
reduced permissible load capacities compared to wheels of GJS-700-2 (GGG 70).
Wheels with Hydropur tyres are particularly suitable for operation on concrete
surfaces owing to the low contact area pressure or in the case of particularly high
acceleration rates of up to 1.5 m/s2 for friction drives due to the high friction coef-
ficient between the travel wheel tyre and counterpart material. This material can be
used at up to 80 ºC for high temperature applications.
Polyamide Compared to GJS-700-2 (GGG 70) travel wheels, travel wheels made of polyam-
ide (PA 6 casting) feature significantly reduced travel noise for comparable friction
values. Attention must also be paid to the significantly reduced permissible load
capacity compared to travel wheels made of GJS-700-2 (GGG 70). Owing to the
high specific contact pressure as a result of the round shape, polyamide is only
suitable for operation on steel materials or similar.

blocks
• Wheel blocks with roller guide arrangement
The permissible horizontal force on wheel blocks fitted with a roller guide ar-
rangement must not exceed 15 % of the actual wheel load. For DRS 112 –
DRS 200 with travel wheel variant E, the value must be limited to 12 %.
Exception: DRS 200 with top connection, the permissible horizontal force must
be limited to 10% of the actual wheel load. If higher horizontal loads are to be
expected, the roller guide arrangement can be fitted to the steel superstructure,
however, not to the wheel block.
• Wheel blocks with roller guide arrangement, fitted to the customer’s

superstructure
The guide roller arrangement as a solo part may transmit 20 % of the permis-
sible wheel load when fitted to the customer’s superstructure.
1.9 Reduction factors for

wheel blocks
for temperature fK A uniform temperature-dependent reduction factor fK is used for the entire wheel
block. It takes into account the temperature-dependent strength of the materials
used as well as the lubricating properties of the anti-friction bearing greases.

2.7.2 Rail systems For spheroidal-graphite cast iron travel wheel, usually rails of steel are used. A
distinction is generally made between two variants:
- Flat rails
k When cylindrical standard travel wheels are used, the load capacity for linear
contact is defined according to section 2.7.4.
Flat rails are described in DIN 1017 or DIN 1014, for example. Depending on
the wheel size and load capacity, flat rails with suitable dimensions and material
quality must be used. See section 2.7.4.1 for frequently used dimensions
41804244.eps
- Rails with convex tread

When cylindrical standard travel wheels are used, the load capacity for point
contact is defined according to section 2.7.5.
In special cases, convex travel wheels are used on flat rails. In this case, the
load capacity for point contact is also defined according to section 2.7.5.
Depending on the national standard, various geometries and material strengths
are available. In Central Europe, A-rails and S-rails are frequently used, grooved
rails more rarely. In Europe, BSC, UIC and QU(KR) rails are also used. In Amer-
ica, ARA, ASCE and CR rails are common. In Asia, IS, JIS and P-rails are used.
See section 2.7.5.1 for frequently used dimensions
42098544.eps
Owing to the sloping head flank surfaces of some rails, they are not suitable for
the use of horizontal guide rollers, see section 4.6.5.
203352_2_enGB_080812

Suitability of rail Assessment criteria for the use of different rail geometries based on:
- Wheel load
- Duty
- Rail support
- Accommodation of lateral forces
2
- Lateral guidance and
- Fitting of wind drift safety devices or tilt safety devices
are explained and described in detail in the VDI 3576 regulations, for example.
ISO 12488 provides additional information about alignment tolerances of crane
travel wheels according to the relevant classification.
The laser alignment device, see section 4.9.7 is available as a tool for aligning the
DRS wheel blocks.
The application of horizontal guide rollers by taking into account the rail fastening
and rail geometry is described in section 4.6.
For recommendations regarding rail or runway for travel wheels of Polyamide or
travel wheels with Hydropur tyres, see section 2.7.7 and section 2.7.8.

2.7.4 Load capacity of the wheel blocks with linear contact
2.7.4.1 Linear contact
Spheroidal graphite cast iron travel wheel material
Flat rail – cylindrical travel wheel
The max. permissible load capacity of the wheel blocks is limited by the per-
missible rail load Rperm (rail) and the effect of the temperature dependence
2
Rperm (temperature).
Rperm (rail) = Rperm (linear) · fSt
Rperm (rail) = permissible wheel load for linear contact on steel rails
Rperm (linear) = permissible wheel load for linear contact
(table value, see page 31 onwards)
fSt = reduction factor for rail material for linear contact, see section 1.9
Permissible wheel loads Rperm (rail) are used in section 5.3 for determining the
maximum permissible wheel load for a wheel block.
Rperm (temperature) = Rperm (linear) · fk
fk = reduction factor for temperature, see section 1.9
Important: Use the smallest calculated value Rperm (temperature) or Rperm (rail) for
further calculation.

2.7.5 Load capacity of the wheel blocks with point contact
2.7.5.1 Point contact
Convex/curved rail – cylindrical travel wheel
Flat rail – convex travel wheel
Note:
2
Cylindrical travel wheels on curved rails are standard, convex special travel wheels
of spheroidal graphite cast iron on flat rails are special cases.
The max. permissible load capacity of the wheel blocks is limited by the
permissible rail load Rperm (rail) and the effect of the temperature dependence
Rperm (temperature).
Rperm (rail) = Rperm (point) · fSt · fRS
Rperm (rail) = permissible wheel load for point contact on steel rails
Rperm (point) = permissible wheel load for point contact
(table value, see pages 42/43)
fSt = reduction factor for rail material for point contact, see section 1.9
fRS = reduction factor for the curve radius for point contact, see the fol-
lowing table

3.11 Shaft system The Demag shaft system for DRS wheel blocks with drives from the Demag modu-
lar geared motor system consists of various shaft types:
Drive shaft Gearbox with solid shafts featuring involute splines

or shaft type A or type DFW for gearboxes with hollow shafts featuring involute
splines.
3
Connecting shaft Type G for central drive units with offset or angular gearboxes in connection with a
coupling.
Important: This shaft type must not be used as a drive shaft.
Connecting shafts are available in the lengths for the five specified track gauges
of 1000, 1400, 2240, 2800 and 3150 mm.
This shaft has to be shortened to the individual track gauge by the customer.
Shortening of the shaft to customer specification is available as an option.
Shaft profile All shafts have a splined profile to DIN 5480 with the following dimensions and

4.4 Buffers Buffers with a high energy absorption capacity are required to prevent any critical
deformation in structural steelwork resulting from travelling units colliding with each
other or with the end of a track.
For cellular foam and rubber buffers, the complete volume of the buffer is utilised
as pressure is distributed over the whole section of the buffer. Lateral deformation
remains low even under maximum compression.
The favourable diameter-to-length ratio of this buffer ensures that any displace-
ment of the buffers due to play in the guidance of the crane rails has no adverse
effect.
4.4.1 Buffer dimensions For buffer impact special load situations, it is assumed that cranes, crabs and
travel carriages, etc. only rarely collide in normal operation.
The required buffer energy absorption capacity must be calculated:
• for the maximum possible buffer impact speed, however, at least k = 70 % of
the travel speed, if speed reduction devices are fitted
• with k = 85 % of the travel speed for cranes
• with k = 100 % of the travel speed for crabs, travel carriages, etc.
(k = buffer energy factor)
4
For an impact between two installations with identical buffers, calculate:
• mass acting on the buffer mpu
mpu mpu1 · mpu2

= mpu1 + mpu2
mpu = mass acting on the buffer

mpu1, mpu2 = mass acting on the buffers of installations 1 and 2
Masses acting on the buffer are the masses acting on the corresponding part of
the buffer depending on the distribution of masses of the structure when the buffer
is impacted. The masses acting on cellular and rubber buffers (DPZ, DPG) can be
doubled when a counterpart buffer of the same size is used.
• Travel speed
v = l v1 l + l v2 l
v = Travel speed
v1, v2 = Individual impact speeds of installations 1 and 2

4.4.2 DPZ cellular plastic buffer Due to its excellent physical qualities as regards elasticity, cushioning and energy
absorption, the cellular polyurethane material is particularly well suited for buffers.
The buffer material is chemically resistant to ozone, oxygen, water, petrol and most
oils and industrial greases. The buffer is fully functional at operating temperatures
of – 20 °C to + 80 °C. In conditions of high humidity in conjunction with high tem-
peratures, the rubber buffer should be used.

With counterbuffer:
The maximum mass which can be buffered is doubled when a counterbuffer of the same size is used. Masses acting on the buffer are the masses acting on the
corresponding part of the buffer depending on the distribution of masses of the structure when the buffer is impacted. The masses acting on cellular and rubber
buffers (DPZ, DPG) can be doubled when a counterpart buffer of the same size is used.
The values given in the table are the maximum masses which can be buffered. It must be considered that deceleration must not exceed 3 g.
4.4.3 DPG rubber buffer The damping material consists of compact elastic rubber. This material has differ-
ent characteristics to that of the cellular plastic buffers.
This buffer material should preferably be used under conditions of high humidity.
The buffer is fully functional at operating temperatures of – 30 °C to + 70 °C.

4.4.4 DPH hydraulic buffer The buffer is an enclosed system consisting of maintenance-free hydraulic ele-
ments. Owing to almost uniform deceleration, this buffer makes it possible to
achieve the smallest possible braking force for the shortest possible brake path.
The permissible ambient operating temperatures range from -12 °C to +90 °C for
adjustable and + 65 °C for self-adjusting buffers; using special seals and special oil
from -40 °C to +120 °C.
The maximum axial deviation of the impact direction from the piston rod axis is ap-
prox. 3°. Hydraulic buffers can be installed in any position.

4.6 Horizontal
guide rollers
4.6.1 General Apart from lateral guidance by means of travel wheels with flanges, the system can
also be guided on the side by means of horizontal guide rollers. The benefits are
that no wear occurs on the flanges and noise development is considerably reduced
owing to the rolling movement of the guide rollers.
Lateral forces • Wheel blocks with flange guide arrangement

The permissible horizontal force on flange-guided wheel blocks must not ex-
ceed 20 % of the actual wheel load.
• Wheel blocks with roller guide arrangement
The permissible horizontal force on wheel blocks fitted with a roller guide ar-
rangement must not exceed 15 % of the actual wheel load. For DRS 112 –
DRS 200 with travel wheel variant E, the value must be limited to max. 12 %.
Exception: DRS 200 with top connection, the permissible horizontal force must
be limited to 10% of the actual wheel load. If higher horizontal loads are to be
expected, the roller guide arrangement can be fitted to the steel superstructure,
however, not to the wheel block.
• Wheel blocks with roller guide arrangement, fitted to the customer’s su-
perstructure
The guide roller arrangement as a solo part may transmit 20 % of the actual
4
wheel load when fitted to the customer’s superstructure.
Ordering information:
If a guide roller arrangement is specified in the type key when ordering a single
wheel block, this is prepared for fitting before leaving the factory. This ordering
information is of particular significance for wheel block sizes DRS 112 – 200.
Suitability of rail Important

For fitting the horizontal guide roller arrangement, make sure it is suitable for appli-
cation in conjunction with the rail fastening (see section 4.6.4) and the type of rail.

Hardening is intended only to minimise wear on the travel wheel. It does not in-
crease the load capacity.

5 Travel unit – rating and specification
A travel unit mainly consists of a travel drive and a wheel block.
5.1 Travel drives

5.1.1 Work cycle A work cycle is usually made up as shown in the following diagram, i.e. 1 x travel
to the left – pause, 1 x travel to the right – pause, with 3 starts being assumed on
average for each travel motion.

The maximum number of cycles is calculated from:
v
S≈ · CDF
2·L
This equation applies on condition that the permissible number of starts is not
exceeded.
S = Number of cycles, work cycle to diagram for one or two speeds

[1/h]
CDF = Relative duty factor of the work cycle [%]
v = Average travel speed [m/min]
L = Travel path (single) with travel motor switched on [m]
203352_5-6_enGB_080812
140
5.1.2 Duty factor Duty factor
Load time Pause
Duration of cycle
41631544.eps
Intermittent duty The ratio of load time to the duration of the cycle is called the relative duty factor
(CDF). Recommended values to EN 600341 are 15, 25, 40 and 60 %. If a 10 min-
ute duration of cycle is not exceeded, the relative duty factor is calculated as fol-
lows:
Sum of load times

CDF = · 100 %
Sum of load times + pauses without current
If the duration of the cycle is greater than 10 minutes, service is considered to be

continuous duty or temporary duty.
Temporary duty For special operating conditions (e.g. long travel path) the ON-time must only be
long enough for the permissible limit temperatures not to be exceeded. In such
5
cases, temporary duty is permitted in place of intermittent duty. In this operating
mode, a travel motor which has cooled down to the temperature of the coolant may
be operated for a certain time with the travel load.
Minimum values for the ON-time for low and high-pole windings are given for the
individual groups of mechanisms in the table, section 5.1.3. No more than 10 starts
may occur during this ON-time.
Mixed duty Intermittent duty and temporary duty alternate in mixed operation. The permissible
limit temperatures must not be exceeded for this duty type.
The specified number of starts per hour applies for travel drives with one travel
speed for intermittent duty. In the case of travel motors for two travel speeds, the
values apply for both windings taken together.
The following conditions are assumed:
Low speed High speed
Starting frequency 2/3 1/3
Duty factor 1/3 2/3
The values apply to equal distribution over an hour. Other calculations are required
for flick-switching (inching operation).
203352_5-6_enGB_080812
141
5.1.3 Starts per hour Minimum values for the starts per hour, the context for the minimum values be-
tween duty factor, number of load cycles per hour and starts per hour are given in
the table (to FEM 9.683).
In practical operation, lower numbers of cycles may also occur in the lower groups
for the given number of starts and higher numbers of cycles, e.g. for automatic
operation, may occur in the higher groups. If travel motors are used in temporary
duty, e.g. for long travel paths, no more than 10 starts may occur. Minimum values
for the ON-time are given in the table for the individual groups of mechanisms.

5.2 Drive specification For the travel drive, the required balancing power at full load must be calculated;
the acceleration and deceleration must be checked.
As an alternative to the calculation, the drive can also be specified with the
Caldrive© software program or configuration can be completed with Drive
Designer. A further alternative for drive specification is provided by the diagrams in
Volume 3 of the Geared travel motors catalogue (203 013 44).
The balancing power can be calculated as follows:
Fw · v
PBal =

PBal = Balancing power [kW]

Fw = Travel resistance [N/t]
v = Travel speed [m/min]
 = Total efficiency of the drive system [–]
It comprises the efficiency of the installation A and the efficiency
of the gearbox Gear. A typical value for the efficiency of the
installation is A = 0.95, so that for travel units with offset gear-
boxes = 0.9 can be assumed.
For data on the gearbox efficiency Gear, refer to the geared mo-
tors catalogue.
5.2.1 Travel resistance The travel resistance mainly depends on

5
– the type of bearings (friction bearing / sliding bearing)

– the condition of the rail used (clean, dusty, sandy)
– the guidance and alignment of the wheels
– the travel wheel material
The travel resistance is composed of the rolling resistance, the friction moment of
the friction bearings and the forces from skewing.
Forces from incline or resistance such as wind forces or trailing cable resistance
must be recorded separately, as required.

5.2.1.2 Hydropur travel wheel tyre Travel wheels with Hydropur-elastomer rims 94 ±2 Shore ‘A’
The traction resistance of travel wheels depends largely on the deformation at the
point on which the wheel stands. In the case of Hydropur-elastomer wheels, the
deformation varies as a function of load and time. The specific traction resistances
are given for 3 possible cases of operation:
Case A: Traction resistance in the travel wheel after several revolutions in opera-
5
tion. Deformation from the rest state has been smoothed out.
Case B: Traction resistance after being at rest for 10 minutes under full load (ini-
tial traction resistance).

traction resistance).

5.2.5 Travel wheel slip torque The gearing of the gearbox is durable for the specified rated torque. The service
life is only limited by the friction bearings, the sealing rings or the lubricant.
In addition, the gearbox must be checked for a gearbox limit load which may occur
when the travel wheels slip or if the travel unit collides with the buffers.
With uniform distribution of the weight, this results in

The gearbox limit torque of the gearboxes is specified in Volume 3 of the Geared
travel motors catalogue (203 013 44).
If Mpu < Mlimit, the gearbox is adequately dimensioned for the application with pos-
sible travel wheel slip torque.
5
Without travel wheel slip torque If Mpu > Mlimit, a larger gearbox must be used or the special load situation of ‘travel
wheel slip torque’ e.g. when there is an impact with the buffer must be excluded.
The assignment of the drives in Volume 3 of the Geared travel motors catalogue
(203 013 44) is made without taking the travel wheel slip torque into account.

5.3 Determining the The maximum permissible wheel load for a wheel block is determined by the mini-
mum of:
maximum permissible
• the travel wheel – rail components, determined over the entire operating time
wheel load
• the wheel block component at increased ambient temperatures or low-tempera-
ture applications
• the wheel block and connection components, determined on the basis of the
number of load changes / vibrations
Rmax perm = Minimum [Rperm (rail) : Rperm (temperature : Rperm (wheel block)]
Rmax perm = Permissible wheel load for one wheel block

Rperm (rail) = Permissible wheel load for travel wheel/rail combination
for linear or point contact (sections 2.7.4 and 2.7.5)
Rperm (temperature) = Permissible wheel load from temperatures (section 1.9)
Rperm (wheel block) = Permissible wheel load for wheel block and connections (sec-
tion 5.3.4)
5.3.1 Determining the mechanisms The mechanisms are classified in groups depending on duty in order to apply the
according to duty given calculation principles.
The group to which a mechanism belongs is determined by the factors
• Operating time class
• Load spectrum
• Load cycle range
5
Operating time class The operating time class specifies the average operating time of a mechanism per
day. A mechanism is considered to be in operation when it is in motion.
For mechanisms which are not used regularly throughout a year, the average oper-
ating time per day is defined by the ratio of the annual operating time to 250 work-
ing days per year.
Higher operating time classes are only reached in multiple-shift operation.

Average cubic wheel load The load spectrum defines to what degree to which a mechanism or a part of it is
subject to its maximum load or only smaller loads.
The cubic average value k with reference to the load capacity is required for exact
classification in the group. This value is calculated using the following equation:

Load cycle ranges Depending on the operating conditions, the total number N of load cycles for the
wheel block may be equal to the number of operating cycles or a multiple thereof;
a load cycle is understood to be each single loading and unloading between pick-
up and depositing of a load and an operating cycle is understood to be the move-
ments required to carry out a complete handling operation.
N1 ≤ 2 · 105 Load cycles
Load cycle ranges N1 to N4 are taken from DIN 15018 (calculation of steel sup-
porting structures for cranes).

Classification of mechanisms in groups makes it possible to define the same

expected service life in years (≈ 10 years) for all load spectra and average daily
operating times. This assumes that the service life of the individual components is
dependent on the cubic number of the load.
Doubling the average daily operating times in the operating time classes or dou-
bling the component parts service life is achieved
• by transferring to a lower load spectrum within a group (1.25 interval),
203352_5-6_enGB_080812
• by reducing the load capacity by a factor of 1.25 on changing to a higher group

within a load spectrum.
Using the defined group of mechanisms, the corresponding permissible wheel load
for the travel wheel/rail combination Rperm (rail) can be found in sections 2.7.4
and 2.7.5.

According to section 2.7.4.2 the max. permissible wheel block load capacity of
9220 kg is given for the wheel-to-rail contact.
According to section 5.3, the max. permissible wheel load results from the mini-
mum of Rperm (rail), Rperm (temperature) and Rperm (wheel block).
According to section 1.9, the following is given with factor fSt for the rail material
(St52-3 in the example) and factor fk for the temperature (up to max. 40 °C in the
example)
Rperm (rail) = Rperm (linear) · fSt = 9220 kg · 1 = 9220 kg

Rperm (temperature) = Rperm (linear) · fk = 9220 kg · 1 = 9220 kg
Rperm (wheel block) indicates the permissible wheel load from wheel block and con-
nections for the number of load changes. Usually this value does not limit the
permissible load capacity as is shown by the following verification according to
203352_5-6_enGB_080812
sections 5.4.5 and 5.4.6.
158
Wheel block service life According to section 5.3.3, the wheel block service life is estimated as follows
( )
Rperm p
Raverage
La (DRS) = Lh (FEM/ISO) ·
dA · taverage
On the basis of 800 hours of full load service life in group of mechanisms 1 Am
(see section 5.1.6) for this example and the 250 working days per year assumed
according to FEM, this service life in years results:
( )
9220 3
6039
L a(DRS) = 800 · ~ 7.1 years
250 · 1.6
The next larger wheel block must be selected if a higher service life is required.
5.4.5 Determining the number of According to section 5.3.6, they are calculated as follows:
service life load cycles
N = La (DRS) · dA · ncycle · taverage · x
A theoretical load changing operation with load pick-up and load depositing is car-
ried out for each operating cycle. For practical purposes (e.g. for aligning the tool
on the carriage and depositing it at an intermediate position) x = 3 load changing
operations per operating cycle is assumed.

N = 7.1 a · 250 d/a · 24 cycles/h · 1.6 h/d· 3 LW/cycle = 205.500 LW
With N (205.500) ≤ N 2 (6 · 105) and load spectrum L2, a utilisation factor of

fa = 1.0 according to section 5.3.6 results for this example

5.4.6 Determining the permissible The max. permissible wheel load for wheel block and connections can be calcu-
wheel load lated as follows:
Rperm (wheel block) = Rmax · fa = 10.000 · 1 = 10.000 kg
Rmax perm = Minimum [Rperm (rail) : Rperm (temperature) : Rperm (wheel block)]
Rmax perm = Minimum [ 9220 kg : 9220 kg : 10.000 kg ] = 9220 kg

5.4.7 Buffer selection DPZ cellular foam buffers are the standard buffers for the DRS wheel block sys-
tem. From section 4.4.2 this implies for:
Travel speed vF = 20 m/min
Cross travel (no speed reduction measures) k = 100%
Maximum mass to be buffered mtot = 32000 kg distributed on 2 buffers per side:

(n ≤ 3600 rpm, geared motors catalogue) indicates approx. 700 permissible brak-
ing operations per hour (c/h) from maximum speed to standstill.

Braking operations per hour ≈ 700 c/h 42505845.eps

203352_5-6_enGB_080812
48 braking operations were required in the application. Additional braking opera-

tions from the low speed no longer have to be checked separately since the friction
energy is 16 times smaller than for braking from the high speed, which would result
in more than 1000 possible braking operations.
The brake is therefore adequately dimensioned.

Travel wheel slip torque The travel wheel slip torque must be calculated for this example as described in
section 5.2.5 in the following way:
Total weight 32000 kg

Rmax = = = 8000 kg
Number of wheels 4
with an adhesion coefficient for GJS (GGG) travel wheels on steel rail of μH = 0.2,
a travel wheel slip torque of
d Number of driven wheels

Mpu = Rmax · μH · g · ·
2 Number of motors
0.2 m 2
Mpu = 8000 kg · 0.2 · 9.81 m/s2 · · = 3140 Nm

The gearbox limit torque of the A...40 gearbox (i = 91.1) with the transmission ratio
of i = 91.1 from geared travel motors catalogue Volume 3, (203 013 44, chapter 3)
results in

Mlimit = 1980 Nm, corresponds to permissible wheel load 10092 kg for the sum
total of the wheel load of a drive chain arrangement
Without travel wheel slip torque Therefore, Mpu > Mlimit and the gearbox is not adequately dimensioned for the ap-
plication with travel wheel slip torque.
The perm. wheel load (Rperm = 10092 kg) is < than the total of the wheel loads (2 x
8000 kg) of the drive chain for a central drive arrangement.
The ‘travel wheel slip torque’ load situation caused by, for example, buffer impact
must be excluded. It this cannot be guaranteed, a larger gearbox must be used. In
this case, select and check gearbox size A50.
Note
For reasons of simplification, a specified standard speed is assumed for this calcu-
lation. The actual speeds in the application are dependent on the actual transmis-
sion ratio, the motor load and, therefore, on the resulting motor speed. This results
in a speed of 688/2815 rpm at full load for this example. Therefore, the actual
speed ranges between 4.75 – 5.04 / 19.4 – 20.3 m/min.
According to the geared motors catalogue (203 151 44) the offset geared motor
model code is specified in accordance with the mounting position as:
