6 AND 7 1/2 TON TRIPLE REEVED UNITS
The following instructions assume that the idler wheel
housing assembly has been attached to the suspension
adapter and hoist frame, there is 6 feet (2 M) of chain
hanging free on the dead end side of the hoist and the
hoist is suspended from the trolley or permanent support..
Based on these, reeve the load chain as follows:
1. Attach a soft wire to the dead end of the chain. Feed
the wire around the lower hook block sheave. MAKING
SURE THERE ARE NO TWISTS IN THE CHAIN, pull the
chain thru the hook block.
2. Feed the soft wire into the outboard side of the idler
wheel housing and around the idler wheel. MAKING
SURE THERE ARE NO TWISTS IN THE CHAIN, pull the
chain over the idler wheel.
3. Remove the wire from the end of the chain and
route chain down to the hook block. MAKING SURE
THERE ARE NO TWISTS IN THE CHAIN, insert the last
link of the chain into the slot in the dead end plate.
Secure the chain using the dead end pin and attach
the dead end plate to top of hook block. Tighten the
dead end plate screws to a seating torque of 120
pound feet (160 NM).
4. Retrace chain and make sure there are no twists. If
there are twists, start over.
liftwheel pockets. If the chain is not properly placed
on the liftwheel, it will not be possible to install the
chain guide. After making sure the chain is correctly
installed on the liftwheel, continue to assemble the
hoist.
4.
On single reeved units, remove the hook block from
the old chain and attach it to the new chain. On

REEVING LOAD CHAIN
3, AND 5 TON DOUBLE REEVED UNITS
The following instructions assume that the trolley has
been removed from the hoist or the upper hook has
been positioned to provide access to the dead end bolt
and that there is 6 feet (2 m) of chain hanging free on
the dead end side of the hoist. Based on these, reeve the
load chain as follows:
1.
Slide the suspension adapter into the hoist frame, if
has moved out of position or if it was removed.
2.
Install the dead end bolt.
3.
Attach a soft wire to the dead end of the chain. Feed
the wire around the hook block sheave. MAKING
SURE THERE ARE NO TWISTS, pull the chain thru the
hook block.
4.
Feed the chain thru the square opening in the chain
plate and then thru the dead end block spacer.
5.
Attach the last link of chain to dead end block using
the dead end pin.
6.
MAKING SURE THERE ARE NO TWISTS IN THE
CHAIN, slide the dead end block into the cavity in
