SHW 8 winch

Top Technology For The Heaviest Of Loads And High Demands

The SHW 8 winch program is based on the tried-and-tested SH wire rope hoist program and is designed for the high-load bracket up to 160,000 kg.

Its strong hoist motors and robust, low-maintenance design make it ideal for tough everyday use. Compared to wire rope hoists, winches only need a few rope reevings even for high loads, making a very compact construction possible. To enable a variety of different economical solutions, there are three motors up to 38 kW with two speeds in a ratio of 1:6 available for the SHW 8 winch. For higher ease of use, there are six hoist motors up to 98 kW with stepless speed control. All travel drives are equipped as standard with soft start. The SHW 8 winch is available on request with high-performance frequency inverters or with individually adapted speeds.

The winch programme is also available in explosion-proof design for Zone 1, Zone 2, Zone 21 or Zone 22.

Models

The different models and trolley variants allow not only a wide variety of uses, but also very individualised solutions tailored to specific requirements.

Stationary model

The SHW 8 winch can be used as stationary hoisting or towing equipment, for example in systems manufacture. Depending on the application, the rope lead-off angle, the attachment of the hoist and the mounting position of the hoist motor can be varied.

OE double rail crab

The OE double rail crab is intended for use on double girder overhead travelling cranes. The extremely compact construction makes very low approach and headroom dimensions possible and the available space can thus be used to the full. The double rail crab is available with various track gauges for the whole load capacity range and automatically compensates for any unevenness of the cross travel runway.

Double-grooved rope drum (True vertical lift)

If true vertical lift is required, we recommend this model with double-grooved rope drum (right-/left-hand thread). This version can be used both in stationary form or with travel carriages.

Double-grooved rope drum (Optional reeving for multiple load pick-up points)

The model with double-grooved rope drum (right-/left-hand thread) is used for many lifting and towing tasks where the load must be picked up at more than one point and true vertical lift is required.

Slide title

The modular design of the SHW 8 winch allows a virtually endless combination of components: therefore – as with the SH wire rope hoist – individual solutions are possible on the highest level of quality.

All mechanical components are bolted
Dismountable for transport
Lifting eyes provide better handling

Options and features

Although they are already first-class in their standard design, you can make the hoists even safer, more economical and more convenient with a range of mechanical, electrical and electronic options. They simultaneously improve performance, prolong service life and make it possible to adapt the hoist individually to specific requirements.

Here are some of the options frequently used.
