Liebherr Presents Simulator for Operator Training on Construction Machinery

  • Liebherr simulator for crawler cranes and deep foundation equipment
  • Focus on efficiency, safety and costs
  • Virtual training under realistic conditions, replication of machines real functions

Nenzing (Austria) July 2014. Liebherr now launched its new simulator for deep foundation and lifting applications. Based on original machine software and hardware the Liebherr simulator (LiSIM®) increases both productivity and safety by providing a cost-effective and highly efficient operator training solution.                  

Finding efficient ways of up-skilling machine operators at the highest safety level while keeping time and costs at a minimum are central demands in the construction business nowadays. Liebherr simulations offer sophisticated solutions that tick all the boxes, allowing trainees to significantly improve their skills in a virtual but realistic environment.

For the simulator, Liebherr’s successful LB 28 rotary drilling rig with continuous flight auger (CFA), Kelly bar and casings as well as an LR 1300 crawler crane have been modelled. In addition, a realistic construction site has been virtually created with adjacent buildings, roads and fences as well as obstacles such as uneven ground, I-beams or rocks.

The drilling rig simulation replicates all aspects of the machine’s real functions: the center of mass changes automatically depending on the attachment; different soil conditions and their effects on both drilling physics and the crawlers of the machine are considered. It offers different training scenarios including basic drilling with Kelly bar as well as travelling with Kelly bar and CFA. In order to train crawler crane operators in a sophisticated way the simulator provides different environment and training scenarios. Full high definition flat screen monitors and high quality surround sound speakers reproduce the views and sounds typically experienced in the operator’s cab; and the motion platform ensures that the operator experiences realistic and accurate movements in a Liebherr simulator.

Focus on safety and efficiency

A major benefit of this type of training is the ability to simulate harsh environmental conditions when required. This allows trainees to gain valuable experience in challenging situations without posing any safety risks. The resulting increase in skill allows for safe and productive operation under similar conditions in the real world.

The sophisticated LiSIM® environmental and physics replication provides an unprecedented level of detail and realism. Thanks to this non-destructible virtual environment, the operator has the opportunity to experience the operational limits of the machine without any consequences, gaining useful experience for highly efficient operation.

Original software and hardware

The installation of original Liebherr control systems, software and hardware guarantees a realistic training experience. The control systems reproduce all movements with exact precision both in space and in real-time. LiSIM® is the only realistic virtual solution available in the market for learning the precise handling of Liebherr’s crawler crane and deep foundation machinery.

Configuration depending on customer needs

Liebherr simulators are available in three configurations. The classroom solution is easily integrated into existing training centres with the display, seat and controls mounted on a base and a sturdy display frame. The space-saving cab solution ensures that the operator becomes familiar with controlling the crane in a real life environment. The easy-to-transport containerized solution houses the simulator in a 40-ft container and features a training room, utility room and cab simulator. Each of the three models is equipped with multifunctional instructor stations.

The development of this advanced training tool is driven by Liebherr’s extensive experience in highly immersive crane operator training as well as in other simulations – last year the company launched its range of maritime simulators for ship to shore, rubber tyre gantry, mobile harbour and offshore cranes.
