Attaching Load Chain - CM LODESTAR 635 Serie Manuel D'entretien, D'opération Et De Pièces

INSTALLATION (CONTINUED)
Now, insert the suspension screws through the holes in the adapter
and hand thread these into the self-locking nuts enclosed in the
hoist frame. These screws will turn freely into the nut until the last
1/4" (6.35 mm) of travel during which the resistance of the nut
locking collar will be encountered. Securely tighten the screws to the
recommended seating torque (see Table 2) using a 12 point socket
which fits the head of the screw.
To rotate the hook 90°, proceed as follows: NOTE: On the rigid
hook suspensions for Models A through RR-2, if it is necessary
to rotate the hook 90°, from its factory set position, one of the
suspension screws becomes captive and a socket cannot be
used to tighten this screw.
1. Using a hammer and drift, drive the pin out of the
square hook collar.
2. Remove the square collar from the hook shank.
3. Place a hi-collar type lockwasher (this lockwasher is not
supplied with the suspension assembly) under the head of one
of the suspension screws. Insert this assembly into the hole in
the suspension adapter and rotate the hook 90° to make this
screw captive.
4. Re-assemble the square collar to the hook shank using the
drive pin previously removed.
5. Follow the instructions above, except tighten the captive screw
to the recommended seating torque (see Table 2) using a 12
point box type wrench.
C. Triple Reeved Units:
These hoists have a sheave hanger which is loosely connected to
the top of the frame by a thin metal plate for shipping purposes.
To attach the suspension, support the sheave hanger from the
underside of the hoist and remove the nut and seat from the sheave
stud. Remove and discard the shipping plate and retain the sheave
stud nut and seat since they will be reused later.
Remove the suspension assembly from the carton and the two
suspension screws. Place the suspension assembly over the sheave
stud and into the recess on top of the hoist.
Insert the suspension screws through the holes in the suspension
adapter and hand thread these into the self-locking nut enclosed
in the hoist. The screws will turn freely into the nuts until the last
1/4" (6.35 mm) of travel, during which the resistance of the nut
locking collar will be encountered. Securely tighten the screws to the
recommended seating torque (see Table 2) using a 12 point socket
which fits the head of the screw.
After the suspension assembly is installed, secure the sheave stud
to the suspension adapter using the round slotted nut and seat that
were formerly used to attach the shipping plate to top of the hoist
frame. Place the seat over the stud with the flat side down and then
rotate the seat so that there is clearance between the seat and the
suspension lug or hook. Assemble the nut to the stud and turn the nut
by hand until the nut seats in the seat and the sheave hanger is snug
in the frame. Then back off the nut until the hole in the stud is in line
with one of the slots in the nut. Using a hammer, drive the retaining
pin (packed with the suspension assembly) into the hole in the sheave
stud until the end of the pin is flush with the edge of the nut.
TABLE 2. RECOMMENDED SEATING TORQUES
FOR SUSPENSION ADAPTER SCREWS
Model No's Screw Size
A thru H-2 3/8"-16 UNC-2A
J thru RRT-2 1/2"-20 UNF-2A
Using other than CM supplied high strength suspension screws to
attach the suspension adapter to the hoist may cause the screws
to break and allow the hoist and load to fall.
Use only the CM supplied suspension screws to attach
the suspension to the hoist and torque these screws to the
recommended seating torque as specified above.
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, damage 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)
