Maximum lifting heights in low rooms

The STK extra short headroom trolley sets new standards. The construction of the short headroom trolley alone saves a tremendous amount of space. The body of the chain hoist is mounted at an angle, meaning that no return sheave is required, thereby allowing a 33 % reduction in headroom. With its headroom reduced by 60 %, the extra short headroom trolley achieves, by contrast, maximum hook paths. The distance from the underside of the beam to the bed of the hook is just 210 mm at a load capacity of 5,000 kg and even just 185 mm at a load capacity of 3,200 kg. The patented chain drive with two separate, but synchronised chains is unique. The load is lifted and positioned exactly without swinging or vibration.

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

  • Very compact dimensions for maximum use of halls
  • Specially developed for low-ceilinged rooms
  • Low deadweight
  • Load is lifted steadily and without swinging
  • Low maintenance
  • Trolleys with no projecting edges for steady cross travel
  • Available as an option in explosionprotected design complying with ATEX and IECEx
  • Two separate chains running in sync act on a hook block, thereby making it possible to lift the load without swinging or vibration.

  • The patented design of the STK extra short headroom trolley permits exceptional lifting heights particularly in low buildings.

    The vertical mounting of the hoist in the case of the extra short headroom trolley permits an extremely small distance between the underside of the beam and the hook bed.

  • A chain hoist, designed as short headroom trolley, is used in a small metal workshop.

    The ST short headroom trolley is based on the tried-and-tested ST chain hoist, which is valued by users, crane manufacturers and system builders alike for its versatility.

  • The extra short headroom trolley is used in the low building of a plastics casting plant for mould changes.

    The patented design of the extra short headroom trolley was developed specifically for use in low buildings, such as this plastics casting plant.

  • This short headroom trolley is used to transport loads over two storeys.

    The inclined hoist of the short headroom trolley permits a 33 % reduction in headroom compared to the ST chain 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.

  • Headroom reduced by 33 % by combining the “short headroom” electric trolley and the ST chain hoist.

    “Short headroom” electric trolley

    The smooth-running electric trolley can also be combined with the ST short headroom chain hoist, reducing the headroom by a further 33 %.

  • Short and extra short headroom trolley

    The construction of the short headroom trolley itself saves a tremendous amount of space. The body of the chain hoist is mounted at an angle, meaning that no return sheave is required. This reduces the headroom by 33 %. The extra short headroom trolley with its headroom reduced by 60 %, by contrast, achieves maximum hook paths, which is particularly beneficial in extremely low-ceilinged rooms. It fully deserves its name. The extremely short distance from the underside of the beam to the bed of the hook is just 210 mm at a load capacity of 5,000 kg and even just 185 mm at a load capacity of 3,200 kg.
