Functions
The load is lifted or lowered by pulling one of the chain falls of the endless hand chain of the hoist. A load
pressure brake prevents automatic lowering of the load after releasing the hand chain.
In combination with hand geared trolleys, the trolley is moved to the left or to the right side by pulling the
hand chain.
In combination with push travel trolleys the trolley is moved by pushing or pulling the load or, without load, by
pulling the load chain.
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. Hardened safety pawls.
Housing
Depending on the model made from steel plate or aluminium die-casting (Not for explosion proof equipment).
In case of ex proof hoists, the housing is only made of steel plates.
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
Forged steel. Rotating, this facilitates attaching the load and avoids twisting of the chain. With safety catch.
Overload protection
Hoists with overload protection protects 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.
