The resistance of the pulley and its
anchorage must be calculated for a double effort of
the lifted load.
2.1.3
Reeving for lifting of load
Use the reeving kit ref 438900.
This assembly allows you to double the capacity of
the device. In return, the speed is decreased by half.
The LM must not be otherwise than with this
reeving kit assembled. Additional system must not
be added.
The reeving kit consists of an anchor carrier strand
and a reeving block with a hook and a spring.
The user should note that when reeving, the
required length of wire rope is at least twice the lift
height, plus at least 1 meter of apparent slack
strand.
The limit spring mounted on the lower pulley is
intended to replace the high limit stop.
A stop may still be placed on the loose strand to
serve as low end stopper.
In case of reeving, double the maximum load
to be taken into account for the calculations of
security.
NOTA : take care to mount the pulley block so that
its limit spring is located on the cable between the
pulley and the entry in the hoist (see figure).
Check the triggering of your travel limit
switch before use; a repositioning of the stoppers
may be necessary depending on the configuration of
job.
Check the capacity of the anchoring points.
When operating with the reeving system, especially
the operator will ensure that the load is not turning
on itself, to avoid tangling the three strands of the
cable (two strands loaded and the slack side).
