7.2 Braking and winding devices
7.2.1 Braking
•
Braking is via a mechanical brake and an electronic generated brake. The brake distance from time of
braking until stopping completely should be within 1.5 % of rope length wound during 1 minute.
This can be determined by simply timing the amount of rope that is wound in 1 minute and calculated
by 1.5%.
•
The rope speed with no load is faster than that with the rated load. The brake distance with no load
will be longer, but still within 1.5% of rope length
7.2.2 Over-winding lift prevention device
▪
A special mechanism prevents over-winding when lifting. When the swivel hook touches the limit lever, lifting
is automatically stopped.
▪
If the limit lever is set to close to the winch body, it will cause serious damage to the limit lever and winch
body.
7.2.3 Reverse-winding prevention device
A special mechanism prevents reverse over-winding:
•
When lowering if the rope is fully extended, this device will cause the wire rope to shift its position from
the front, toward the back.
•
To disengage this device the wire rope needs to be shifted back to the front position. To do this pull
and hold the rope downward and press the ↑ button.
