Refer to Dwg. MHP3044 on page 8.
To feed load chain through bottom hook assembly:
1. Install the ‘C’ link in the last link of the load chain extending from the hoist (A).
Connect the new load chain to the ‘C’ link. The end link must be a standing link
(perpendicular to the axle of hoist sprockets).
2. Run the hoist to feed the chain through the hoist body and down to (C) on the
hook block.
3. The axis of the sprocket wheel (120) in hook block assembly must be
perpendicular to the rotation axle of hoist sprockets (30) and (50) of the hoist.
4. Insert the last link of the load chain in the opening to bottom block (C). The first
link must be inserted parallel to the axis. The sprocket of bottom hook assembly
and the following standing links must have the welds turned to the outside
position with the sprocket. Refer to Dwg. MHP0472 on page 7.
5. After exiting the bottom hook assembly at (D), feed the last link of the load chain
into hoist opening (E) and around sprocket (50).
6. After exiting the hoist at (F), position the last link of the load chain in the slot
(G) in the bottom hook assembly and attach it with anchor pin (219) and retainer
ring (224).
WARNING
• The chain must not be twisted.
7. On the free end of the load chain, install buffer (4) with capscrew (5) and nut
(7) (this buffer activates the bottom switch limit). As a minimum attach the
buffer to the 9th link from the load chain end.
