Hooks.
Both upper and lower hooks must be free
to swivel. Those that are held by nuts must be
adjusted to provide 1/32” clearance as shown in
Figure 15 before the hook nut pin is inserted.
FIGURE 15. Hook Mounting
Lower Hook Thrust Bearings.
The 1/4 thru 6
ton lower hook thrust bearings are mounted with
the outer shell down (see Figure 15).
Hand Chain.
Hand chain must have an odd
number of links.
Join the ends with the “hand chain connecting
link”(646-45) so that there is no twist in the
completed chain loop. The connecting link must
be completely closed so that it will seat in the
handwheel the same as the welded links.
REEVING
Improper installation (reeving) of the load
chain can result in a dropped load.
To Avoid Injury:
Reeve and attach the ends of the load in
accordance with the following instructions.
1/4-1/2-1 Ton Hoists
Attach approximately 20 inches of wire to the
loose end of the load chain. Feed the wire around
the liftwheel as shown in Figure 16 until the first
link starts over it. The first and third links must
stand on edge with the weld away from the lift-
wheel. After the chain has been started, pull the
hand chain or turn the handwheel in the hoisting
direction until about 2 feet of load chain has
passed over the liftwheel.
If it becomes difficult to pull the hand chain in
the hoisting direction, pull it in the lowering
direction to release the load chain. Start over. This
will prevent the load chain from being jammed
between the liftwheel and frame.
Remove the wire and attach the loose end of
chain to the hoist using the loose end screw and
washer (see Figure 16). The chain must not be
twisted between the liftwheel and loose end screw.
FIGURE 16. Reeving ¼-½-1 Ton Hoists
Mount hoist in a vertical position and check that the
lower hook is on the same side of the liftwheel as the
upper hook and in line with it.
1 1/2-2 Ton Hoists
Attach approximately 20 inches of wire to the loose
end of the load chain. Feed the wire around the lift-
wheel as shown in Figure 17 until the first link starts
over it. The first link must lay flat on the liftwheel.
The second link must stand on edge with the weld
away from the liftwheel. After the chain has been
started, pull the hand chain or turn the handwheel in
the hoisting direction until about 2 feet of load chain
has passed over the liftwheel.
If it become difficult to pull the hand chain in the
hoisting direction, pull it in the lowering direction to
release the load chain. Start over. This will prevent the
load chain from being jammed between the liftwheel
and frame.
Remove the wire and attach the loose end of chain to
the hoist using the loose end screw, washer and lock-
washer (see Figure 17). The chain must not be twisted
between the liftwheel and loose end screw.
Mount hoist in a vertical position and check that the
lower hook is on the same side of the liftwheel as the
upper hook and in line with it.
