Also, do not apply any type of lubricant to the threads of
these screws. Lubricating the threads will reduce the effort to
seat the screws and as a result, tightening the screws to the
(Table 2) recommended torque may break the screw, dam-
age the suspension adapter, strip the nuts and/or damage
the hoist frame.
ATTACHING LOAD CHAIN
To attach the chain to the dead end block on Models E, E-2,
H, H-2, R, R-2 and RR-2, proceed as follows:
1. Suspend the hoist from an adequate support.
2. On Models E, E-2, H and H-2, insert the last link of the
load chain into the dead end block (2) and secure it with
the dead end pin, washer and cotter pin furnished with
the suspension.
3. On Models R, R-2, RR and RR-2, slide the contact block
up the chain until it is against the bottom of the hoist and
the dead end block is projecting through the square
opening in the bottom of the block. Insert the last link of
the load chain, making sure there are no twists between
the hook block and the dead end block, into the dead
end block. Push the contact block up slightly and secure
the load chain to the dead end block using the dead end
pin, washer and cotter pin furnished with the suspension.
The dead end pin also supports the contact block (See
Figure 8)

4. Do not remove the plastic ties from the load chain at this
time.
After the suspension is installed, hoists with a hook suspen-
sion can be suspended from its permanent support and then
connected to the power supply system (refer to page 8). For
hoists with a lug suspension that are to be suspended from a
Series 635 Low Headroom Trolley, attach the hoist to the trol-
ley per the following instructions.
INSTALLING THE SERIES 635 LOW
HEADROOM TROLLEY (See Figure 9)
.
Figure 9. Series 635 Low Headroom Trolley: 1 and 2 Ton (1000 and 2000
kg) Trolley Shown- 3 Ton (3000 kg) Similar.
For hoists with a lug suspension that are to be suspended
from a Series 635 Motor Driven Trolley, attach the hoist to the
trolley, wire the hoist and trolley together and connect the
trolley to the power supply system per the instructions
supplied with the trolley.
The stops must be positioned so as to not exert impact force
on the hoist frame or trolley wheels. They must contact the
ends of the trolley side frames.
It is recommended that the trolley be mounted on the beam
prior to attaching the hoist to the trolley. Before attempting to
mount the trolley on the beam, measure the actual width of
the beam flange on which the trolley is to operate. Using the
measurement and Table 3, determine the arrangement of the
spacer washers. Loosely assemble the side frames, load
bracket, spacer washers and nuts on the suspension bolts
as shown in Table 3.

WARNING
Operating the trolley on a beam that has no rail stops may
allow the trolley to fall off the end of beam.
TO AVOID INJURY:
Install rail stops at each end of the beam on which the trolley
is to operate.
