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

Liebherr develops and constructs gear ring rope winches for the highest demands.

Liebherr develops and constructs gear ring rope winches for the highest demands.

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.

With a tare weight of 180 tonnes the ZSW 2400 is the largest and heaviest rope winch offered by Liebherr.

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.

The ZSW 1400 gear ring rope winch is used as a hoisting winch in the largest LR 13000 crawler crane ever manufactured by Liebherr.The image shows the crawler crane on a special assignment in Bremerhaven.

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.
