Gear ring rope winches for optimum rope pull forces
At extreme rope pull forces, the use of Liebherr gear ring rope winches speaks for itself. The advantages, among other things, are a redundant drive system and new, rope-safe winding mechanism. The clever design results in high operational safety and longevity.
Optimum rope speeds and rope capacities
Our gear ring rope winches are distinguished by a compact design and well-engineered safety equipment. At the same time, Liebherr gear ring rope winches enable high rope speeds and rope capacities. Output torques of up to 2,500 kilonewton metres (kNm) are achieved here in the most cost effective way via a gear ring from several externally located electric or hydraulic slewing drives. High energy efficiency is assured by the optional Pactronic system from Liebherr.Liebherr Pactronic: optional hybrid-based drive system
Safe, available and durable
Due to their redundancy, the slewing drives of Liebherr gear ring rope winches offer reliable operational safety. A new type of rope-safe winding mechanism contributes towards the high availability and longevity. Moreover, Liebherr has developed a patented system safety geometry. Subsequent damage from overload in the drive system is prevented in this way.
Gear ring rope winches for individual requirements
With Liebherr gear ring rope winches, the focus is on individual solutions: a range of different output torques, transmission ratios and dimensions are available. The version is chosen according to the project and application. The seals and cooling are also adapted to the specific needs as required.
Intensive engineering support as well as approval inspection by certification authorities enhance the range of services offered by Liebherr.
