Increase the efficiency of your winch systems: Thanks to the improved power density, new materials and reduced component complexity of Liebherr LPI gearboxes, you can design winch solutions that are significantly lighter.
Due to the improved power density of the new LPI gearbox series, a larger power ratio can be implemented in a smaller installation space. Thanks to the smaller winch drum, you save material and thus costs.
A wide range of configuration options, such as brake types, protective coatings or gearbox seals, ensures that Liebherr LPI gearboxes are particularly suitable for winches in onshore and offshore applications.
For the best possible drive combination of gearbox and motor, the interfaces to the motor are designed in such a way that any commercially available electric and hydraulic motor can be attached without great effort.
Compact and heavy-duty rope winches are mainly used for low to medium rope pulling forces. A planetary gearbox integrated in the rope drum transmits torques between 6,000 and 944,000Nm to the rope drum via the inner wheel. Depending on requirements, two gear units can also be integrated for a drive on both sides.
For the highest rope pulling forces, such as those encountered in heavy-duty and crawler cranes, deep-sea winches and other special applications, gear ring rope winches are used. Output torques of up to 2,500 kNm are most economically applied via a gear ring of several external rotary drives, which can be electrically or hydraulically driven. Due to their redundancy, the gearboxes offer high operational reliability of the rope winch.
Based on many years of experience as a component manufacturer, Liebherr supplies winch systems for various applications in the field of lifting and handling technology as well as in adjustment systems. The winch systems developed according to the modular principle cover a wide range of customer needs and thus enable system delivery with minimum development times.
Whether series or individual winch solution: On request, acceptance by one of the common certification bodies is possible, such as American Bureau of Shipping [ABS], Det Norske Veritas - Germanischer Lloyd [DNV GL] or Lloyds Register of Shipping [LRS].
