STAHL CraneSystems GmbH : STD Vario dual chain hoist

STD Vario dual chain hoist –
safe transport of loads of different lengths

Using their many years of experience and intelligent technology, R&D engineers from STAHL CraneSystems worked together in close contact with customers to develop the STD dual chain hoist further. The result: the STD Vario dual chain hoist with electrically adjustable spacing between the hooks, a further gain in work safety and flexibility. The STD Vario is especially suitable for transporting long loads of different lengths (e.g. rods, timber beams and steel girders).

Disadvantages when using two individual chain hoists		Disadvantages when using a dual chain hoist with lifting beam

Completely synchronous operation not possible Trolley spacing necessary Complex power supply The spacing between the hooks can change when driving the crabs, thereby causing dangerous load situations		Lifting beam requires additional headroom or reduces the height of lift The hooks on the lifting beam must either be moved "manually" or if they are moved automatically, an additional power supply to the beam is necessary Lop-sided load distribution can occur
