Winding up of wire rope
The wire rope must always be winded up tensioned. When the last wire rope layer is winded onto the drum,
the flanged wheel must exceed the top layer by at least 1 1/2 times of the wire rope diameter.
NOTICE!
According to validated regulations and accident prevention regulations, the wire rope length must be
chosen so that at least 2 rope layers remain on the drum when the wire rope is unwinded.
6.5
Wire rope deflection
Wire rope pulleys must be installed in a
position centrically to the rope drum.
In order to ensure correct winding up of the
wire rope on the drum, the max. wire rope
deflection angle must not be exceeded.
maximum wire rope deflection angle
4° for standard wire ropes
2° for non-twisting resp. twist-resistant wire
ropes
The minimum dimension (M) from the drum
until the middle of the pulley must be adhered
to.

NOTICE!
Should the drum be extended and for some models with limit switch, the distance "M" must be increased.
Standard values:
15x 1/2 drum length for standard wire ropes
30x 1/2 drum length for twist-resistant or non-twisting wire ropes
