Variable steering concept with „active rear-axle steering“
Axles 3, 4 and 5 set up as „active rear-axle steering, 5 steering methods are preselectable by fixed programs (P):
P1: On-road steering
Axles 1 and 2 are steered mechanically with hydraulic assistance by the steering wheel. Axles 3, 4 and 5 are steered „actively“ speed-dependent, subject to the cramp of the front axles, and over 30 km/h, axles 3 and 4 are set to straight displacement and fixed, from 60 km/h, axle 5 is fixed equally to straight displacement. The change of the steering angle in accordance with the speed, results in a precise and stable driving quality during higher speeds, tyre abrasion is reduced and the maneuverability clearly improved.
P2: All-wheel steering
Axles 3, 4 and 5, dependent on the steering angle of axle 1 are cramped by means of the steering wheel so that the smallest turning radii can be performed.
P3: Crab steering
Axles 3, 4 and 5 are cramped into the same direction as axles 1 and 2 by means of the steering wheel.
P4: Steering without swerving
Axles 3, 4 and 5 are cramped in accordance with axle 1 so that no swerve out of the rear of the carrier takes place.
P5: Independent rear-axle steering
Axles 1 and 2 are cramped by the steering wheel, axles 3, 4 and 5 steered independent of the cramp of axles 1 and 2 by momentary-contact buttons, whereby the cramp of axle 3 is adapted to the required situation.
• A failure in the rear-axle steering makes it ineffective and the rear axles are set to straight displacement by the centering rams
• Two independent hydraulic circuits with wheel- and engine­driven hydraulic pump, thus maximum safety standard
• Two independent control processors (by existing E/A modules) and diversified sensoriel system
• Entire know-how of the „active rear-axle steering“ by Liebherr

Outstanding boom technology
The advantages of the boom technology at a glance
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.
• 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

Data bus technique revolutionises the crane electric system
The Liebherr mobile cranes are entirely equipped with data bus transfer systems. The digital system is the basis for the data bus. It permits the transfer of a multitude of information almost parallel and faultless via one only cable. Liebherr has developed its own system bus (LSB) which corresponds to the manifold requirements in respect to all possible mobile crane operations. All important electrical and electronical components on the superstructure, such as length sensors, angle sensors, load cells, proximity switches, master switches and hoist limit switch are equipped with their own microprocessors and communicate via various data bus networks. The keyboard and display units, the outrigger control as well as the engine and transmission control on the vehicle are intelligent function blocks and equipped with bus interfaces. A continuous self-test of the sensors during operation guarantees a high functional reliability. The internetworking of the LICCON computer system with the system bus establishes entirely new and comprehensive diagnostic facilities in respect to the crane.
The advantages of the data bus technique at a glance
• Reduction of the operating costs due to a modern engine and transmission management (CAN bus system); increased economy due to improved endurance of the individual units
• Improved reliability due to a considerably reduced number of electrical cables and contacts
• A continuous self-test of the „intelligent sensors“ guarantees a maximum of reliability
• Comprehensive diagnostic facilities - quick error detection
• Self-manufactured bus systems, specially adapted to the requirements of a mobile crane
• The data bus technique increases the comfort and safety during driving and crane operation

The LICCON test system
• The test system assists the servicing personnel in quickly localizing failures of the crane sensory system without the need of measuring instruments
• The service starts on the display screen, troubleshooting becomes a matter of seconds
• Occurring errors are indicated by error codes and error descriptions on the display screen
• Convenient interactive functions permit the observation of all inputs and outputs of the entire system by different representations on the display screen even during crane operation. It equally visualizes the allocation of the individual sensors and actuators of the system and their functions.
The LICCON work area limitation system
• It relieves the crane operator, especially in situations where the handling of loads requires his full attention, by controlling the work area limits. Work areas can be restricted by buildings, bridges, roofs, high-tension power lines, pipelines or adjacent cranes. The automatic work area limitation system (optional), can easily be programmed. Four different limitation functions are practicable:
• Height limitation of the pulley head
• Radius limitation
• Slewing angle limitation
• Limitation of edges
The LICCON work planner
• The LICCON work planner consists of a software program on CD for planning, simulation and documentation of crane applications on the display screen (optional)
• The 2D planner program enables the drawing of buildings, to write texts and to represent a crane model true to scale including the entire motions within a fictional construction site
• The work planner permits the preparation of more transparent offers, facilitates the briefing of crane operators and can be run on a Laptop at the construction site

Electronic SPS crane control with test system
• Control of the winches, slewing gear and the luffing and telescoping motions by the LICCON computer system (PLC control)
• Four working motions can be performed independently of one another

with hydraulic interlocking device
• Hoist gear and slewing gear operate within a "closed oil circuit". This enables very sensitive lifting/lowering of loads, or slewing. Moreover, during lowering of the load, the potential energy generated is not converted into heat but can be re­employed for a second motion. This saves fuel and the oil does not reach as high a temperature as during operation within an open circuit.
