3. Ensure the chain is straight and attach the free end to the
chain anchor bracket. Refer to Dwg. TPA706-1, ‘Chain
Installation - Step 4.’
4. Inspect to ensure chain is not twisted, kinked or “capsized”.
Refer to Dwg. MHP0020 and MHP0043.
HL4500K and HL6000K
The following steps describe the initial installation of chain on
three or four fall hoists that do not have load chain installed.
1.
Remove the brake spring and piston housing, brake discs
and brake plates to expose the brake driver.
2. Place the edge of the first link of load chain in a pocket of
the hoist powered chain wheel. Refer to Dwg. MHP0472.
The weld on the load chain link must face away from the
powered chain wheel pocket.
CAUTION
• Improper installation of the load chain will cause
premature wear of the chain wheels resulting in damaged
equipment, which can cause injury or property damage.
3. Rotate the brake driver by hand to feed the load chain
through the hoist in the direction of the dead end chain
anchor (raise direction).
4. Keep the load chain straight, do not twist it. Attach the free
end of the load chain to the connecting link. Refer to Dwg.
TPA1056 for HL4500K and Dwg. TPA1057 for HL6000K.
Clean and inspect the brake parts and assemble.
5. On HL6000K hoists, slide the limit stop tube onto the load
chain.
6. Keeping the load chain straight, complete the load chain
installation as described in either the HL4500K or
HL6000K ‘Hoist Load Chain Reeving’ section.
HL4500K Hoist Load Chain Reeving
Refer to Dwg. TPA1056.
After the load chain has been correctly installed onto the hoist
powered chain wheel it must be carefully routed through the
lower block idler chain wheel, the upper suspension idler chain
wheel and secured to the bottom block housing as described in
this section.
WARNING
• Twisted load chain can jam as it passes over the chain
wheel causing damage to the hoist or breaking the load chain
which can cause injury or property damage.
1. Raise the bottom hook block to a position near the hoist
where it can be properly supported and restrained from
movement.
2. Ensure the load chain remains straight. Feed load chain
through bottom block idler chain wheel.
