Refer to Dwg. MHP2338 on page 6, A. Weld; B. Feed first link perpendicular to
load sheave; C. Power Head Load Sheave; D. Hoist Motor Side; E. Chain Stopper; F.
Weld on perpendicular chain link must face away from top sheave. Weld on flat chain
link must face away from hoist motor side; G. Bottom Block.
1. The hoist should be installed and connected to air supply. Reduce hoist air
pressure to 60 psi (4 bar/414 kPa).
2. Remove chain bucket, if used.
3. Remove load chain stopper.
4. Remove bottom block assembly.
5. Cut new load chain to length. Load chain must have an even number of links
(first and last links must be at 90˚ to each other). Refer to Dwg.
MHP2336on page 5.
6. Run hoist slowly in lifting direction until load chain free end is approximately 2
ft. (0.6 m) from hoist.
7. Using a ‘C’ link which is the same size as load chain join new load chain to old
taking care that weld on perpendicular links on new load chain are facing away
from hoist load sheave.
8. Run hoist slowly until new load chain has passed 2 to 3 feet (0.6 to 1 m) through
hoist. Remove ‘C’ link and old chain.
9. Install chain stopper in last link of load chain free end.
10. Install bottom block assembly.
11. Lubricate entire length of load chain before operating hoist. Refer to
“LUBRICATION” section in Product Information Manual.

HA3-050 Hoist
Refer to Dwg. MHP2339 on page 6, A. Weld; B. Feed first link perpendicular to
load sheave; C. Power Head Load Sheave; D. Hoist Motor Side; E. Chain Stopper; F.
Weld on perpendicular chain links must face away from sheaves. Weld on flat chain
links must face away from hoist motor side; G. Bottom Block; H. Anchor Chain at this
point.
1. The hoist should be installed and connected to air supply. Reduce hoist air
pressure to 60 psi (4 bar/414 kPa).
2. Remove chain bucket, if used.
3. Remove load chain stopper.
4. Run hoist slowly in lifting direction until bottom block assembly is approximately
3 ft. (1 m) from hoist power head. Firmly support and secure bottom block
assembly in this position.
WARNING
• Do not begin chain replacement until bottom block assembly is fully
secured and supported. If bottom block assembly or chain are dropped,
they could cause injury or damage property.
5. Cut new load chain to length. Load chain must have an even number of links
(first and last links must be at 90˚ to each other). Refer to Dwg. MHP2336
on page 5.
6. Remove pins that anchor load chain to power head assembly.
7. Using a ‘C’ link which is the same size as load chain join new load chain to free
end on old chain taking care that weld on perpendicular standing links on new
chain are facing away from hoist load sheave.
8. Run hoist slowly until new load chain has passed through hoist. Continue
running hoist and pull chain by hand through bottom block assembly. Begin
feeding chain at position ‘A’ and work alphabetically. Remove ‘C’ link and old
chain.
9. Anchor end of load chain to power head assembly. Install chain stopper in last
link of load chain free end.
10. Lubricate entire length of load chain before operating hoist. Refer to
“LUBRICATION” section in Product Information Manual.
