With the new jacking system, Liebherr delivers a cost-efficient solution to lift the excavator uppercarriage for easy swing ring maintenance or replacement.
Liebherr delivers a wide range of service tools for excavator-specific maintenance: pump, cylinder, travel drive, track pad maintenance or replacement, ensuring optimal working conditions no matter the size of the component. The close collaboration between the excavator R&D engineering team and service tools development team ensures that the excavator design encapsulates best-practice serviceability, according to the manufacturer.
The tooling design and product range evolve with the excavators.
Liebherr Service Tool development meets stringent EC and Australian standards. Before release, Liebherr tooling undergoes an intensive factory and field testing program to meet the challenges faced in the field and exceed the expectations of the end user.
With the new jacking system, Liebherr delivers a cost-efficient solution to lift the excavator uppercarriage for easy swing ring maintenance or replacement. Equipped with four synchronous columns for optimum precision and control, the jacking system is a safer and more efficient alternative to the complex crane lift. The ergonomic and compact wireless remote control provides unimpeded movement. Via integrated LCD display, the user can instantly view the health of the jacking system. It is compatible with Liebherr mining backhoes and face shovels from the R 9250 up to the R 9800.
To complete this solution, Liebherr has developed the service powerpack. Fixed to the undercarriage and connected to a generator set, this additional module provides hydraulic power to separate the undercarriage from the uppercarriage. It offers full control of the undercarriage including track chain tensioning and release of the travel brakes. The remote control enables proportional steering for easy and precise undercarriage displacement.
Another specific service tool is the pin puller, which provides safety and simplicity when extracting and inserting pressed pins into and from the excavator’s attachment, according to the manufacturer.
This tool is available in three sizes across the entire range of Liebherr mining excavators.
With the track condition monitoring system, Liebherr provides all specialized electronic and mechanical measurement tools to monitor the wear of the track chain and its components. This system is delivered with dedicated software to track wear of components and facilitate forecasting of spare parts.
