Description
Designed for road transportation.
When disassembled the crawler crane has a compact transport width of maximum 3 metres, which permits cost-effective transportation with standard low loaders. The connecting pieces of the luffing jib can also be transported in the connecting pieces of the main boom to save space. Fewer transport vehicles are therefore required.
High service availability.
A global service network
with experienced technicians
and fast access to spare parts
ensure high machine availability
and a long product service life.
Self-loading and self-assembly system.
The innovative self-assembly and self-loading system enables
unloading and assembly without an auxiliary crane. For crawler
cranes in this size category, more cost-effective transportation
and quick commissioning play an instrumental role in efficient
operation.
Comfort
This includes a modern air-conditioning
system with improved airflow, an optimized
field of vision and reduced noise protection,
as well as an orthopaedic operator’s seat with
integrated heating and cooling.
Ground Pressure Visualization
The Ground Pressure Visualization calculates
the current ground pressure of the machine in
real time and compares it with the specified
safety limits of the relevant position.
Consideration of wind speed
Both the measured wind speed and the actual
crane configuration are taken into consideration
when calculating the current hazardous situation
for the crane. When the conditions become too dangerous,
the system gives a warning.

Virtual crane operation plan
Confined spatial conditions, as well as special ground conditions, are key factors for the configuration of the device. As a solution, with the “Crane Planner” Liebherr offers software for selecting the optimal crawler crane and the appropriate configuration for the respective use.
Boom Up-and-Down Aid
The assistance system “Boom Up-and-Down Aid”
indicates the approach to the tipping border
and automatically stops operation before the
operator unintentionally enters an unsafe zone.
Personnel lifting
The crane is approved for personnel
lifting. The statutory emergency generator
and emergency controls required for personnel
lifting are offered by Liebherr as a simple
Plug-and-Play solution.
Horizontal load path
This control assistance system
increases the comfort in the operation
of the crane. Loads can be moved to their
intended position more efficiently. Coordination
is also simplified for multi-crane lifting.
Vertical Line Finder
The Vertical Line Finder ensures
that the boom head is moved exactly
vertical over the load to be lifted.This prevents the load swinging and
possible contact with obstacles, as well as people. The service life of the crane is also increased with the lower dynamics on the boom.
Radio remote control
With the radio remote control a second person outside the cab
can assume all crane movements. Loads can be moved to positions
which are not even visible to the operator himself. Safety on the
construction site is thus
increased considerably.
