Areas of application
The devices must be as far as possible installed in a covered room.
If they are used in the open, protect the units against the effects of weather such as rain, hail, snow, direct
sunshine, dust, etc. - we recommend to use a cover in parking position. If the device is set up in a
continuously humid environment with strong temperature fluctuations, the correct functionings are
endangered by the forming of condensation.
Ambient temperature -20°C up to +50°C. Power-operated units -20 up to +40°C. Humidity 100 % or less but
not under water

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.
