Sophisticated technology – customised and perfect

System solutions adapted individually to specific customer requirements are STAHL CraneSystems’ forte. Virtually no other manufacturer of hoisting and crane technology offers such a variety of custom solutions with such quality and such efficiency. We develop the best technical solution for every requirement. The modular ST chain hoist programme forms the basis for the wide variety of versions. For example, dual chain hoists, multiple reeved chain hoists, STB Big Bag version and coupled chain hoists for four-point load attachment.

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