Manual Tiger SS11-PLH En 201704 v3.2
Load Limiter
Your SS11 or PROLH may have been supplied with a load limiter, if this has been requested at the time of order.
The load limiter (S-60) is fitted to prevent hoist overload. The device operates by limiting the amount of torque transmitted by
the operating handle. It is independent of the hoist brake.
If a load limiter is fitted, items LL-3, LL-17 and LL-34 replace the standard Pinion Shaft (S-03/PRO-03), Grip Ring (S-34/PRO-34)
and Change Gear (S-17/PRO-17).
See Chapter 13 for the explosion diagram of the lever hoist without load limiter.
To set the load limiter:
Follow the instructions below to reset a load limiter after servicing or to readjust the torque setting.
If the load limiter components have been disassembled the lever hoist including load limiter parts LL-3 and LL17 will need to
be reassembled up to the handle stage. Then follow instructions from number 4 below.
1.
To reset the load limiter you will need to remove parts to access the lock nut:
S-39/PRO-39 Pinion Nut
S-32/PRO-32 Washer
S-37/PRO-37 Screw for Guide Plate
S-38/PRO-38 Switch Set
S-36/PRO-36 Retaining Spring
S-35/PRO-35 Guide Plate
LL-34 grip ring.
2.
Remove the Grub Screw from the Lock Nut with a 2.5mm hex/Allen key.
3.
Using a 46mm socket or spanner unscrew the Lock Nut, but do not remove it. This will reset the torque to zero.
4.
Suspend the lever hoist from a test machine, using a load cell to monitor the load.
