For crawler undercarriages and mobile, track-driven applications that are at the cutting edge, the issues of weight saving, power density and fuel saving play a central role. With a completely new design concept, fewer components and new materials, the gearboxes of the new LPI series make a decisive contribution in said areas.
The advantages for manufacturers of mobile applications are obvious: Undercarriages and chassis can be designed significantly more compact and lighter with LPI transmissions thanks to their low weight and reduced installation space. Both factors reduce fuel and energy consumption and thus increase the efficiency and cost-effectiveness of the application.
Liebherr LPI gearboxes are easy and optimally configurable, the connections are suitable for both hydraulic motors and electric motors.
Whether new design or retrofit: LPI gearboxes can show out their strengths to the fullest in combination with electric motors. Together with Liebherr high-speed gearboxes as a preliminary stage, you can rely on smaller electric motors and frequency converters. In this way, the entire electric drive system remains compact, cost-effective and yet powerful.
The compact design of LPI gearboxes saves weight and fuel: A smaller LPI gearbox size when comparing to common gearboxes can mean up to half a ton less weight of the undercarriage. A clear advantage also in terms of emission savings.
If your machinery has to withstand particularly high loads, Liebherr also offers FAT travel drives in its portfolio.
In the mining sector in particular, Liebherr excavators and crawlers have withstood the toughest loads in continuous operation for decades. With the FAT travel drives, you therefore benefit from a knowledge resource that will pay off in your applications.
