Removing Load Chain
1. Hoist must be hung and connected to air supply. Reduce air pressure to 60 psi
(4 bar).
2. Remove chain bucket.
3. Support the hook assembly 6 to 9 feet (2 to 4 meters) below the trolley. On
LC2A120D, LC2A180T and LC2A250Q hoists disconnect the load chain end from
the hook assembly or support.
4. Remove chain buffer and limit stop at chain bucket end of load chain.
5. Using an abrasive wheel, cut a section from the last link as shown in Dwg.
MHP0817 on page 7, A. ’A’ Dimension; B. ’C’ Link. Use a ’C’ link which is the same
size as the load chain. Refer to Table 6 ’C’ Link Dimension’ on page 7.

LC2A060S Load Chain Installation
Follow instructions 1 to 5 under ‘Removing Load Chain’ on page 7. Also:
1. Remove hook assembly.
2. Install the ‘C’ Link in the last link of the load chain that was attached to the hook.
3. Connect the new load chain using the ‘C’ link. Make sure the welds on the new
chain links are in the same positions as they are on the old chain.
4. Slowly run the hoist in the lifting direction, running off the old chain and feeding
the new load chain over the chain wheel and through the hoist body. Refer to
Dwg. MHP3160 on page 7 for chain reeving information.
5. After the new load chain exits the hoist, remove the ‘C’ link. Install the buffer
(370) with capscrew (371), washer (374) and nut (372) on the chain bucket end.
6. Install the hook on the hook end of the chain.
