Reeving the
hoist rope
Depending on the version, you can use the rigging aid for fitting the hoist
rope if necessary;
à p. 6 - 48.
Adjusting the head sheave
The head sheave can be shifted into two
different positions (1) and (2).
The required position depends on the reeving.
Reeving images show the head sheaves in the
positions (1) and (2).
The head sheave must always be shifted into
the position via which the hoist rope will run –
for example, into position (2).
Shifting the head sheave
• (A) – Pull the rod (5) out.
• Turn the lever (3) so that it is located below
the cutouts (1) or (2).
• (B) – Push the head sheave (4) into the
required position – e.g. into position (2).
• Turn the lever (3) into the appropriate
cutout – e.g. into cutout (2).
• Insert the rod (5) and secure it with the
retaining pins.

Danger due to slack rope!
Only use hook blocks and lifting gear of the minimum weight prescribed in
the
Lifting capacity table, depending on the reeving and boom length. This
prevents slack rope forming at large heights when lifting without a load.
This can result in the load slipping.
