Reliable measurement in harsh environments

LiView in new crawler loader generation

Work with a crawler can sometimes release enormous forces. For our new generation of crawler loaders, it was important for us to have a position transducer on par with the machine's performance.

LiView is an intelligent position transducer for hydraulic cylinders that provides precise measurement data for reliable control of the bucket in the new Liebherr LR 636 G8 crawler loader – even under the most demanding conditions.

In mobile machines, assistance systems relieve the driver and can significantly increase efficiency. When hydraulic cylinders are involved, assistance systems require precise measurement data on the exact position of the cylinder. LiView reliably delivers this measurement data with its unique mode of operation.

LR 636 G8 crawler loader

Moving 23,000 kg is a cinch: with its numerous driver assistance systems and ergonomic cab the LR 636 G8 crawler loader ensures optimum operating comfort and enables fatigue-free work..

Automatic lifting, lowering and tipping of the loading bucket with LiView data

In the new LR 636 G8 crawler, the LiView position transducer provides precise measurement data on the tipping and lifting cylinders. This allows the driver, among other things, to activate automatic lifting and lowering of the bucket. This function is intended for loading work, where the lifting gear is to be repeatedly raised or lowered to a certain height. Once the set position is reached, the lifting or lowering stops automatically.

Likewise, a position can be stored for tipping of the loading bucket in and out, which can be automatically controlled via the hydraulic sensor.

LiView has proven to be a reliable and, above all, robust solution here – thanks to its unique measuring principle and the great flexibility in the positioning of the electronics module.

Robust and easy to integrate

The LR 636 G8's areas of application include earthworks and landfill sites. It is suitable for applications that require extremely high breakout forces.

LiView is the ideal partner. The position transducer uses the cylinder itself as an extremely robust sensing element, making it ideally suited to the high demands of the LR 636 G8.

  • Free positioning

    Free positioning of the electronics module

    The processing electronics can be installed either directly on the outside of the cylinder or in any location near the cylinder. In the LR 636 G8, the LiView electronics module for the lifting cylinder is installed under the cab. In addition, the LR 636 G8 has a second LiView electronics module for the tilt cylinder, which is also located in the machine, just slightly further forward.

  • Easy integration

    Easy integration

    The position transducer consists of the electronics module and two probes. Only the two probes require a connection in the piston rod bearing - which means they are quickly and easily integrated.

  • Relief for the driver

    Relief for the driver through assistance systems

    The driver can activate the assistance systems based on LiView data directly on the touch display in the driver's cab.

    In the LR 636 G8 crawler loader, LiView measures the position of the Liebherr cylinders. Liebherr manufactures high quality and durable cylinders with factory-installed LiView probes and checks the cylinder with an integrated position transducer. The OEM receives a fully tested cylinder and can connect the electronics module directly, making it quick and easy to put the fully equipped component into operation. Liebherr hydraulic cylinders from the 380 bar series production range can be ordered with the position transducer already integrated. In addition to Liebherr's own cylinders, LiView is also suitable for numerous other cylinder types.
