Comfortable crane cab
of high functionality
The focal points of the successful boom technology for the
Liebherr mobile cranes are the oviform boom profile, the
internal interlocking system of the telescopes and the
telescoping system „Telematik“.
The oviform boom profile
It features a particular inherent stability against deflection and
torsion. In steep boom position as well as at large radii, the
oval boom profile offers optimal lifting capacities.
The patented internal interlocking system of
the telescopes
The interlocking process of the telescoping ram with a boom
section is performed successively by spring-loaded pins, and
followed by the mechanical release of the same section of the
telescopic boom. This method guarantees that a telescope
release can only take place if the telescopic section is
interlocked with the hydraulic ram.
The automatic telescoping system „Telematik“
An outstanding flexibility in controlling the various telescoping
lengths of the boom is achieved by the rapid-cycle telescoping
system. The most suitable boom configuration can be
preselected dependent on the job requirements. The
telescoping of the boom is practicable either by manual or
fully automatic control. The saving of time during the automatic
telescoping procedure and the combinatorial variety of the
telescoping paths determine the functionality of the telescopic
booms.
Outstanding
boom technology
• Considerable increase in lifting height and reach due to
extraordinarily long telescopic booms
• Telescopic booms of inherent and lateral stability for maximum
lifting capacity requirements
• Outstanding functionality due to the automatic telescoping
system „Telematik“
• High working speeds due to the fully automatic telescoping
procedure
• Outstandingly easy operation - control of the telescoping
procedure by means of telescoping images on the LICCON
display screen
• Maintenance-free telescoping system
