Functions
The lifting gear and motor-driven trolley are moved by pressing the buttons on the control switch. The spring-
pressure brake installed in the electric motor of the lifting gear prevents the independent lowering of the load
after the push button has been released.
By using a frequency converter, the speed is infinitely variable.
Hand geared trolleys are moved to the left or right by pulling one of the two stands of the endless 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.
If the hoist is not used very often, we recommend to carry out a test run at least once a week and to switch
on the motor several times during this test run.
In our experience, this will prevent the brake from sticking.

Important components
Standard 3-phase current motor
Hoist gear
precision spur gear
All gears are fitted with vent screw.
Trolley gear motor
Combination of worm gear and motor.
Closed design - ventilation not necessary
Overload protection and emergency end limitation
Hoist with overload protection
Slipping clutch
The overload control is set in the factory according to the regulations; it is possible to adjust it later from
outside (see repair and maintenance section).
The slipping clutch prevents the lifting of a load that is too heavy by slipping through. In the standard design
with direct control the slipping clutch also takes on the function of an emergency final limit when the load is at
the highest and lowest position.
