On starting the work of unloading the vehicle, the electric chain hoist has a cold temperature of approx. 20 °C.
Running time =
= 1 min, 4 sec
Approx. 20 minutes operation without break is possible. This covers
18 lifting cycles x 6300 kg carrying load = 113.400 kg goods can be transported.
After 20 minutes of running time, 3 minutes break for each minute of operating time must be taken (i.e. 3 times the
operating time). This break is usually necessary for slinging and taking off loads.
Caution!
Cooling periods are imperative for extreme lifting heights (from 10 metres on). Precision lifting
should only be used for precise lowering and lifting. It is not suitable when greater lifting heights are
involved.
Option!
To protect the lifting motor a thermal overload device is offered as an option.
Duty rate of a motorised trolley
If the hoist is equipped with an electric trolley the operators have to take care of the duty rating of the trolley as well.

Strainer clamp for the control cable
The strainer clamp must be fixed in such a way as to
prevent any tensile forces affecting the control cable.
Pulling the chain hoist at the control pendant by means of
the strainer clamp is not permitted.

Lubrication
Gear lubrication
The gear is filled with two litres of oil by the manufacturer. If the oil is drained it has to be disposed in accordance with the
laws of environment protection. The oil has to be changed only if the hoist is going to be overhauled. If the oil has to be
changed, use oil for a temperature range of -20° to+40°C and viscosity of 220 mm²/s at 40°C.
Lubrication of the hook block and hook tackle
Lubricate the anti-friction bearings on the hook and the chain sprocket after approx. 20,000 lifting cycles
or a year, if in heavy use shorten the interval, use a special anti- friction bearing grease.
Lubrication of the trolleys
The geared wheels of the electric trolley have to be lubricated by grease once a year or after 10,000
driving cycles, if in heavy use the interval has to be shortened.
Disposal
After the hoist or its components are taken finally out of operation the parts have to be disposed in accordance to the
laws of environment protection.
Metals, rubber, plastics have to be disposed or recycled separately.
