The Hand-emergency lowering device consists of a closed hand wheel, as well as a brake release device.
The brake system, can be opened by use of the brake release lever.
Controlled emergency lowering of the load is possible via the sensitive operation of the brake release lever.
The lowering speed can be controlled with the brake lever. The closed hand wheel turns by the release
brake and by the winch operation, with the motor speed.
The winch is assembled in such a way that you find the turning hand wheel outside of the possible
danger zone. Should the situation arise, a collapsible shield can be provided on site.
The hand wheel can also be used up to maximum 10% of the nominal load for installation work.
It is not recommended to lift great distances since the short lift per hand wheel turn is very slight. (Required
hand force and lift per turn of the hand wheel will be advised when ordered).
In order to turn the hand wheel, the brake device has to be activated at the same time.
The turning moment works directly on the hand wheel.
The total winch, including the emergency release device, must be tested by an expert for its respec-
tive usage.
Upon request, and against an additional charge, a centrifugal brake can be installed in order to brake the
lowering speed with an emergency reduction operation.
The emergency release device is only allowed to be activated in an emergency and only by
trained personnel! The operator is responsible for ensuring a safe lowering speed is main-
tained!
