4.2 Design
HADEF electrical chain hoists are equipped with a suspension eye for stationary use. The one and two chain
fall devices may optionally be equipped with a suspension hook.
All devices can also be supplied with monorail trolley with push travel, hand geared or electric drive.
Type 62/05 S, stationary
Type 62/05 R, with push travel trolley
Type 62/05 H, with gear travel trolley
Type 62/05 E, with electric travel trolley
Plan:
Chain falls
1/1 2/1
Operational limit switches for lifting and lowering
4.3 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.
