Suspending the chain hoist

5.6.1

Supporting structure

DANGER
Overload
There is a danger to life and limb due to overloading the supporting structure.
The supporting structure must be designed for the maximum load of the chain hoist when being used appropriately.
According to DIN EN 14492-2, hoist units with a load capacity ≥ 1000 kg must be equipped with an overload pro‐
tection.
DC-Com chain hoists are equipped with a slipping clutch which directly acts as overload protection. The slipping
clutch must be adjusted to the load capacity of the chain hoist. Information on the adjustment see brochure "Friction
force checking device" ⇒ Tab. 3, Page 7.
According to DIN EN 14492-2, the force limitation factor for DC-Com chain hoists with a load capacity ≥ 1000 kg is:
ϕ = 1,6
DAL
The static and dynamic forces which occur when the overload protection is tripped must be taken into account when
designing the supporting structure.
