Functions
The load is lifted, lowered or tensioned by operating the lever. The load pressure brake prevents automatic
lowering of the load.
NOTICE!
If used "overhead" or "lashing" undefined forces may appear. We recommend to use a hoist with
slipping clutch for these cases.
NOTICE!
The best protection against functional failures in case of extreme environmental impact is the regular use of
the equipment.

Important components
Gear
Gear components are made of high-quality material.
Load pressure brake
Holds the load in any position.
A new brake system is used for the hoists (except
for the Aluminium Ratchet Lever Hoists). Brake
discs have sintered brake linings which are
designed for the lifetime of the devices when used
as intended.
According to DIN 13157 lifetime is 1500 operating
cycles (lifting/lowering movements) with 300 mm
lift with nominal load.

Housing
Depending on the model made from steel plate or aluminium.
Load chain
According to EN 818-7-T high quality chain. All components match precisely to each other. Therefore please
only use original chains.
Load hook with safety catch
Forged steel. Rotating, this facilitates attaching the load and avoids twisting of the chain.
Ship hook with safety catch – as option
Ratchet Lever Hoists of capacity 1600 kg and 3200 kg can be fitted with ship hook - as option
The hook tip may only be loaded for tightening.
For lift and lower use, the load must lie on
on the hook base and the hook safety catch
must be closed.

DANGER!
In hazardous area, the load on the hook tip is prohibited!
Free-wheeling of chain
For pulling through of the uncharged chain.
Overload protection
Hoists with overload protection protect the hoist by a slipping clutch from damage by overload. When the
slipping clutch operates, lifting of the load is stopped. Lifting is only possible again after the load has been
lowered and reduced to nominal load.
Special Parts
For use in explosion dangerous areas, are be installed some special units, special treated surfaces or made
in special material.
