Intelligent crane control with LICCON

Liebherr mobile cranes are controlled precisely using intelligent technology. The LICCON computer system is at the heart of all this. Liebherr designs and produces the software and hardware for the mobile crane control in-house. Our specialists continue to work on the development of the control's architecture to meet the ever growing demands of the market.

LICCON sets the very highest safety standards. The crane control can automatically monitor precise compliance with the operating range limits in a constricted space.

Flexible control system from a single source

LICCON (Liebherr computer control) is the most modern computer system in the world for controlling and monitoring mobile cranes. All the key components, including the software, has been developed by Liebherr in-house. This enables us to guarantee reliability, quality and future spare parts availability.

The crane control with integral LML load moment limiter meets the very highest safety standards. The electronic control system is tailored individually to each crane. Its freely programmable nature means that it can be adjusted flexibly to suit individual requirements. Particularly important in practice use: The Liebherr crane control is insensitive to ambient influences such as extreme temperatures.

Technological pioneer

Liebherr developed the first computer-based crane control in 1989 – a genuine milestone in the industry. In 2007 the LICCON2 successor system was launched, featuring much higher computing capacity and additional applications. Another reason behind Liebherr's success is its reliable data bus transmission equipment which revolutionised crane technology at the end of the 1990s.

User-friendly functions and benefits

System display for the working range limits

System display for the working range limits

LICCON allows the working range limits to be programmed and monitored automatically at the touch of a button.

LICCON allows the working range limits to be monitored automatically.

Benefits of the working range limiting system

  • Working range limits can be defined simply at the touch of a button.
  • The programmed limits can be enabled and disabled easily.
  • The operating movements are stopped with damping.

Functions at a glance

The system allows the following functions to be used singly or in combination:

  • Pulley head height limit
  • Radius limit
  • Slewing angle limit
  • Edge limit

Sample view of a crane job simulation using LICCON

The LICCON work planner allows the computer-based simulation of crane jobs using the lifting case parameters of load, radius and hoist height.

The LICCON work planner is a software package for planning, simulating and documenting crane jobs on a PC and in the crane cabine.

Benefits of the work planner

  • All the lifting capacity tables for a crane are shown.
  • After entering the lifting case parameters of load, radius and hoist height, the planner suggests the best cranes for the job.
  • Drawing functions and support force display allow crane jobs to be simulated realistically.
BTT Bluetooth terminal for the remote control of crane set-up functions

BTT Bluetooth terminal for the remote control of crane set-up functions

The multi-functional control and display unit enables the crane's set-up functions to be controlled quickly and easily from outside the cab.

The BTT Bluetooth terminal is a multi-functional control and display unit for the remote control of crane set-up functions.

Benefits of the Bluetooth terminal

  • Fast, easy and safe to use
  • Clear visibility and proximity to the operation
  • Greater comfort
  • Increase in efficiency

Support crane

The BTT enables a mobile crane's outriggers to be extended safely and easily. Engine start/stop and engine speed control, electronic inclination display and automatic support levelling are included as standard. If necessary the support forces can also be displayed on the BTT.

Detaching the hook block with visual contact

Detaching the hook block with visual contact

This function makes the driver's workload much easier since the hook block can be attached and detached when in visual contact.

Attach and detach hook block

The BTT also enables the crane driver to attach and detach the hook block with visual contact. For this purpose the hoist winch and luffing cylinder for the telescopic boom are controlled remotely.

Additional functions

Depending on the crane model and equipment, the BTT can control other functions such as the folding jib or ballast erection.

Complete remote control for controlling all crane movements

Complete remote control for controlling all crane movements

The remote control allows all the crane functions to be controlled from outside the cabine. A major benefit for crane operators: The console can also be used for other cranes with a LICCON2 control which have been programmed for remote control.

The Liebherr LICCON2 crane control system also provides the possibility of an easy and low cost extension to the complete radio remote control of the crane. In addition to the software, only a console with the two master switches is required. The existing BTT is plugged to this. This means that all crane movements can be controlled from outside the crane cabine.

Benefits of remote control

  • Greater economy
  • A clear sight and proximity to the load
  • Prevention of communication errors between the crane driver and site personnel
