Safe transport of long loads

The STD dual chain hoist was developed specifically for long material and loads that need to be picked up at two points. It is equipped with two load chains, which are moved synchronously by a hoist motor. The hook spacing can be selected at will in dependence on the material being transported. The two synchronised rope lead-offs lift and transport the load without dangerous slant by design. The two load hooks work absolutely safely and in sync even in the case of materials of different lengths or uneven loading. Thanks to its low headroom, the STD dual chain hoist is also suitable for low buildings and achieves maximum hook paths.

The chain hoists are also available in explosion-proof design for Zone 1, Zone 21 and Zone 22.

  • Low space requirement permitting maximum height of lift
  • Two hook lead-offs running in synch on one hoist
  • Synchronous lifting even with uneven loading, no tilting of the load
  • Individually adapted to width of load
  • Low maintenance
  • Optionally available in explosionprotected design complying with ATEX and IECEx
  • Loads of different lengths can be lifted without problem with the help of the electrically adjustable hook spacing of the STD Vario dual chain hoist.

  • The two synchronised rope lead-offs ensure safe transport of long material such as, for example, heavy reels of paper.

  • A dual chain hoist lifts complete car bodes and transports them through the assembly line.

    Using special lifting beams, the dual chain hoist can also lift complete car bodies and transport them safely through the assembly line.

  • A special crane with height-reduced endcarriages and an individually adapted STD 50 dual chain hoist works in a burnishing line.

    This custom hoist in a chemical plant consists of an STD 50 dual chain hoist with two synchronised rope lead-offs and an ST 20 as auxiliary hoist.

Models

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