ASSEMBLY INSTRUCTIONS
SWIVEL HOOK SUSPENSION
Models R & RR.
Assemble the dead end bolt and block through the suspen-
sion adapter as shown in Figure 21.

INSTRUCTIONS FOR ASSEMBLING UPPER
SUSPENSION TO HOIST-
DOUBLE REEVED CHAIN MODELS
Place the suspension assembly into the recess provided on
the hoist. The dead end block should project through the
bottom of the hoist with the pin hole and slot aligned to the
underside of the hoist as shown in the Figure 8 pg. 4. If
these are not aligned as shown, lift the head of the bolt from
the hex recess in the adapter and turn the bolt and block
assembly and reseat the bolt head to obtain proper align-
ment.
DO NOT change the position of the dead end block on
the bolt to attain this alignment.
Check the postion of the pin hole in the dead end block to
make sure that it has not been disturbed from its factory set-
tings. The distance from the top of the pin hole to the bottom
of the hoist should not exceed 7/16” (11mm) for Models R &
RR. If the distance is not correct, adjust the position of the
dead end block to obtain the proper distance.
CAUTION: DO
NOT apply oil or any other lubricant to the threads of the
suspension adapter screws. Such lubricant will significantly
affect the frictional characteristics and may damage the
screw or nut if the screw is tightened to the recommended
seating torques.
Now, insert the screws, supplied with the assembly, through
the holes in the suspension adapter and thread these into
the self locking nut enclosed in the hoist. The screws will
turn freely into the nut until the last 1/4” (6.35mm) of travel
during which the resistance of the nut locking collar will be
encountered. Security tighten the screws to the recommend-
ed seating torque specified in Table 9, using a 12 point
socket (½” socket) which fits the head of the screw.
The dead end of the load chain is temporarily positioned (a
few links from the end) by a wire clip.
DO NOT remove this
clip before attaching the chain to the dead end block. Refer
to Figure 7, page 4 and the tag attached to the load chain on
the hoist.

INSTRUCTIONS FOR ASSEMBLING UPPER HOOK
SUSPENSION TO HOIST-SINGLE CHAIN MODELS
Place the suspension assembly into the recess on the top of
the hoist so that the adapter body follows the contour of the
hoist.
CAUTION: DO NOT apply oil or any other lubricant to
the threads of the suspension adapter screws. Such lubri-
cant will significantly affect the frictional characteristics and
may damage the screw or nut if the screw is tightened to the
recommended seating torques. Insert the screws, supplied
with this assembly, through the holes in the adapter and
thread these into the self locking nuts enclosed in the hoist.
The screws will turn freely into the nuts until the last 1/4”
(6.35mm) of travel during which the resistance of the nut
locking collar will be encountered. Securely tighten the
screws to the recommended seating torque specified in
Table 9, using a 12 point socket (½” 13mm) which fits the
head of the screw.
W WA AR RN NIIN NG G
The suspension screws are special high strength screws
and under no circumstances should screws other than
these be used to attach the supsension to the hoist. If other
than the suppled, high strength screws are used, they may
break and allow the hoist to fall from the support and this
may result in an accident that could cause injury and/or
property damage.
