Wolffkran

Location: Zug, Switzerland

Industry: Construction

Application: Crane Technology

Rated torque range between 27.5 and 175 kNm

Increased center distance to accommodate the motor and rope drum on one side of the gearbox (U-configuration)

High rotational speeds

Externally mounted intermediate shaft for mounting a disk brake

Customized gearbox design for optimal adaptation to the available installation space and operating conditions
In addition to customer-specific gear unit designs, hoist gear units with an extended center distance—based on the established X.. series—are also available as standardized versions

No need for oversizing of the gear units, as the U-configuration of the rope drum and motor is achieved through an increased center distance

Optimal adaptation to the available installation space and operating conditions

In addition to hoist gearboxes, we also supply drive units for the trolleys

On-site support through our global presence

At the heart of the cranes are the hoisting winches, which are used to move loads ranging from 6 t to 60 t for several hours a day. The trend toward ever-taller buildings also means that the hoisting distances of cranes are becoming increasingly longer. As a result, hoisting winches now have up to 1,000 m of rope wound onto them.

This results in loads that also affect the drive technology used. The hoist gearbox, in particular, plays a key role here. In addition to high power density, long-term reliability is a decisive criterion when selecting a hoist gearbox. Additional requirements, such as short delivery times and a straightforward gear selection process, are particularly important to crane manufacturers when choosing a gear supplier.
