Functional Description

The wall winches are drum winches with a spur gear. The load is automatically held by load pressure brake.
The winch housing is made of plated steel and is suitable for mounting, especially onto walls, masts and similar
installations.
The length of the crank arm is to be adapted to the load and therefore adjustable in the length.
The bearing of the worm shaft as well as the rope drum is through rolling bearing respectively friction bearing.
Mounting:
ATTENTION:
♦ The mounting structure must be designed to sustain
the max. forces imposed by the winch,
♦ Pay attention that the mounting surface is flat and true
Wire rope fixing
ATTENTION:
With wrong rope coiling the brake is not effective
Rope coiling has to be effected according to the drawing
The wire rope descent must unconditionally (see illustration) follow from the rear
drum border in the upward direction.
The arrow in the picture has the same direction as the crank with the load going
upwards.
Pay attention to correct rope direction (see picture)
The fastening of the wire rope is to be made with the built-in rope clamping
device.
For rope selection pay attention to the technical data for the rope.
Calculate the rope length in such a way that at least 3 full turns of rope remain on
the drum in lowest load position.
Operating Instructions
At least 25 % of the nominal load must be on the winch as load for the proper working of the friction brake.
Safety Instruction: The winches are only suited for manual operation.
Lifting the load by turning the crank in clockwise direction.
Lowering the load by turning the crank in counter-clockwise direction.
