Remarks
1. The lifting capacities stated are valid for lifting operation only
(corresponding with crane classification according to F.E.M.
1.0 01. cra ne g rou p A1).
2. Crane standing on firm, horizontal ground.
3. The weight of the lifting device (hoisting ropes, hook block,
shackle etc.) must be deducted form the gross lifting capacity to
obtain a net lifting value.
4. Additional equipment on boom (e.g. boom walkways, auxiliary jib)
must be deducted to get the net lifting capacity.
5. For max. wind speed please refer to lift chart in operator‘s cab
or manual.
6. Working radii are measured from center of swing and under load.
7. The lifting capacities are valid for 360 degrees of swing.
8. Calculation of stability under load is based on ANSI/ASME B 30.5
load ratings as well as ISO 4305 Table 2 and is tested according
to SAE J765.
9. Loads for calculation of structures are corresponding to F.E.M.
1.001-1998 and are tested according to SAE J987.

Hydraulic system
A double axial displacement pump supplies the open loop hydraulic
system, allowing all functions to be operated simultaneously. To
minimize peak pressure an automatic working pressure cut–off is
integrated in the pump.
All filters are electronically monitored.
The use of synthetic environmentally friendly (biodegradable) oils is
possible.

The winches are outstanding in their compact design and easy
assembly.
Propulsion is via a planetary gearbox in an oil bath.
Load support by the hydraulic system; additional safety factor provided
by a spring loaded, multi–disc holding brake.
The main winches use pressure controlled, variable flow hydraulic
motors. This system features sensors that automatically adjust oil flow
to provide max. winch speed depending on load.
Option – winch with free-fall system:
Clutch and braking functions on the free-fall system are provided by a
compact designed, low wear and maintenance-free multi–disc brake.

Swing
Consists of rollerbearing with external teeth, swing drive with fixed
axial piston hydraulic motor, spring loaded and hydraulically released
multi–disc holding brake, planetary gearbox and pinion.
Both swing modes are possible – speed control or free swing.
A multi– disc holding brake acts automatically at zero swing motion.
Swing speed from 0 – 3 rpm continuously variable.
Control
The hear t of the hydraulic crawler cranes is the Liebherr control system
which has been developed and manufactured in-house.
It includes all control and monitoring functions and is designed to
withstand extreme environmental conditions and heavy duty
construction tasks. Complete machine operating data as well as
warning signals and irregularities are clearly displayed on the high
resolution monitor in the operator‘s cab in the required language.
The electro-hydraulic proportional control allows several movements to
be performed simultaneously. This ensures that all categories of loads
can be positioned with utmost precision.
