Liebherr will highlight hydraulic, digital and other advanced technologies
Liebherr's parts division intends to showcase a variety of products, many of which will showcase digital and alternative energy advances.
Digital technologies on display include camera monitors and surround vision systems that use sensors and software to improve visibility around machines. An integrated digital wear measurement system, called Bearing Clearance Monitoring (BCM), for monitoring the swing bearings will also be displayed. Force measuring sensors for hydraulic cylinders will also be displayed.
Liebherr Components said in the press release on the technology that BCM can measure the axial and radial bearing wear and tilt clearance. "An obvious disadvantage of all common wear measurement methods is that service technicians must install a dial indicator or other measuring equipment directly on the swing bearing in the hazardous area below the excavator or other machines," explained Wolfram Halder, swing product manager. "The Liebherr BCM system makes this unnecessary because the measuring equipment has been permanently installed on the bearings."
In addition, BCM eliminates the dependence on external service providers to measure the bearing clearance, because the sensors are integrated into the bearings, the bearings communicate with the gateway, and the data is stored on the gateway, so that the machine owner can access the data through the application.
The bearing clearance monitoring system uses integrated sensors to monitor bearing wear, direction and clearance in heavy equipment. Information is stored and accessed through mobile applications.
In terms of hydraulics, the company has introduced a new online hydraulic cylinder configurator, which provides 3D models of various hydraulic cylinders of the company to help OEMs select appropriate hydraulic cylinders for their applications. Hydraulic cylinders made of composite fibers will also be on display, showing solutions that offer lightweight options to help reduce the use of machine fuel.
Liebherr Components shows its axial piston pump LH30VO series, which now includes pumps with a nominal displacement of 100cc and pumps with a displacement of 28cc, 45cc and 85cc. This will provide more choices for OEM customers. The pump's modular controller system can be used to help improve its performance and efficiency.
For alternative drive systems, the company has developed a hydrogen fueled engine with a diesel version with many common components. The company also offers hydrogen injection technology. It is also developing electric turbochargers to help optimize the performance of hydrogen powered equipment. Liebherr Components explained in its press release announcing its bauma exhibition plan that its system approach integrating compressors and power electronics can save weight and cost, as well as reliable technology that is easy to integrate into vehicles.
