Reeving rope
The wire rope is wound onto the drum in the factory. If not, see page 80, section
7.14.4
“
Repl
acing wire rope”
.
The wire rope hoist must be switched on in order to reeve the rope. All work must
therefore be carried out with extreme care: for your safety and for smooth functioning of
the wire rope hoist!
If the bottom hook block is not fitted, proceed as follows:
1.
Gripper pliers hold the rope securely with a gripper pliers.
2.
Lay out the end of the rope not wound on the drum, or let it hang freely.
3.
Check that the wire rope lies snugly on the rope drum, tighten if necessary.
If the fit is loose:
Dismount the rope guide, see page 79, section
“Removing rope guide”
Tighten up the wire rope on the rope drum and tension.
Mount the rope guide, see page 81, section
“Fitting rope guide”
NOTICE
Material damage hazard.
Slack rope can destroy the rope guide and the wire rope.
Avoid slack rope on the drum.
Fig. 46
1.
Color code the beginning of the rope on one side.
Reeve the end of the rope into the rope sheave(s) of the bottom hook block and return
pulley(s) (see next page for details).
NOTICE
Material damage hazard to wire rope.
Do not twist the rope, the color coding facilitates
checking.
2.
Fasten the end of the rope in the rope anchorage
3.
Perform several runs over the full height of lift without load.
4.
Repeat with increasing loads.
5.
Make any twisting in the rope which may occur visible by sticking on a paper tag.
Severe twisting is shown by the bottom hook block's turning, especially when not
under load.
NOTICE
Material damage hazard.
Twisted ropes compromise safety and damage the rope.
If any twisting occurs, remove the wire rope and untwist by letting it hang freely or laying
it out. Twisting in the wire rope prejudices safety and service life.
Any twisting must therefore be removed before subjecting the hoist to any further load.
The rope could otherwise be permanently distorted and might have to be replaced!

NOTICE
Reeve the rope as shown in the schematic drawings and attach the end of the rope at
the rope anchorage. The bottom hook block must hang horizontally (./2-1)
The hook may rotate after a short time in operation due to residual stress in the rope
