Initial Chain Installation
The following instructions apply to hoists that do not have load
chain installed. For hoists with load chain installed, that must be
replaced, refer to the ‘Chain Replacement’ section. When
directed to remove or install hoist sections or subassemblies to
assist in chain installation, refer to the applicable ‘Disassembly’
or ‘Assembly’ section for specific requirements.
HL1000K, HL1000KR and HL1500K
The following steps describe the initial installation of chain on
single 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.
From the side of the chain wheel opposite the chain anchor
bolt, engage the first link of load chain in a pocket of the
chain wheel on edge. Refer to Dwg. TPA706-4, ‘Chain
Installation - Step 1.’ The weld on the load chain link must
face away from the powered chain wheel. Refer to Dwg.
MHP0472.
3.
Rotate the brake driver by hand to feed the load chain
through the hoist.
(Dwg. TPA706-4)
4.
Keep the load chain straight and do not twist it. Attach the
free end of the load chain to the connecting link. Refer to
Dwg. TPA706-3, ‘Chain Installation - Step 2.’ Clean,
inspect and install the brake spring, brake discs, brake
plates and piston housing on hoist.
5.
Attach free end of load chain to hook. Inspect chain while
operating hoist slowly. Ensure chain feeds through chain
wheel smoothly, without sticking or binding. Repeat
operation in the opposite direction.
HL2000K and HL3000K
The following steps describe the initial installation of chain on
double fall hoists that do not have load chain installed.
1.
Complete steps 1 through 4 of “HL1000K, HL1000KR and
HL1500K Chain Installation” section. Refer to MHP0472,
TPA706-4, and TPA706-3.
WARNING
• Replacement chain for an HLK double fall hoist must have
an ODD number of total links. Refer to Dwg. MHP0441.
2.
Ensure the chain is straight and feed the end through the
bottom hook chain wheel with the first link on edge with
the weld to the inside of the idler chain wheel. Refer to
Dwg. TPA706-2, ‘Chain Installation - Step 3.’
