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.

  • Series components from the SH range, field-proven in thousands of applications
  • Modular design for cost-effective individual solutions, simple transport and speedy erection
  • Versatile drive technology meets demanding specifications: 3 hoist motors up to 38 kW with two speeds in a ratio of 1:6 and 6 hoist motors up to 98 kW and stepless speed control
  • All travel drives with smooth starting characteristics
  • Overload cut-off pre-set during manufacture
  • Compact headroom thanks to innovative rope drive design
  • 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 five motors up to 200 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 modular construction of the SHW 8 winch makes it possible to transport the winch in its individual parts and to assemble it again on site quickly.

  • Double girder overhead travelling crane in a production hall at Ford in India.

    This SHW 8 winch is designed for particularly high speeds and equipped with tool grippers.

  • SHW 8 winch and two SH wire rope hoists

    The SHW 8 winch is particularly maintenance-friendly as its clean assembly grants the service technician easy access to all important components.

  • SHW 8 winch with two SH wire rope hoists

    The innovative design of the rope drive enables the very low headroom of the SHW 8 winch.

Models

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

  • Diagram of the SHW 8 winch in stationary design.

    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.

  • View of the SHW 8 winch on a double rail crab.

    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.

  • Three wire rope variants of a double-grooved rope drum with the reevings 4/2-1, 8/2-1 und 12/-1

    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.

  • Two wire rope variants of a double-grooved rope drum with multipoint load attachment with the reevings 2/2-2 and 4/2-2

    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.
