Custom Solutions

Sophisticated Technology – Customised And Perfect

System solutions adapted individually to specific custom solutions 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 chains, dual chain hoists, multiple reeved chain hoists, STB Big Bag version and coupled chains and chain hoists for four-point load attachment.


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


  • Optimally matched to your project
  • Every hoist is the result of over 140 years of experience and expertise
  • Short development time
  • Cost-effective thanks to modular system
  • Technically mature thanks to the use of field-proven standard components
  • High quality and reliability ensured by in-house production
  • All customised solutions are available as an option in explosion protected design complying with ATEX and IECEx.
