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.

Securley 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 suspenison

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 con-

nected to the top of the frame by a thin metal plate for ship-

ping 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 disgard

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 sus-

pension 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 slot-

ted nut and seat that were formerly used to attach the ship-

ping 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 ham-

mer, 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

RECOMMENDED

SEATING TORQUE

A thru H-2 3/8”-16 UNC-2A 30 to 45 lb. ft.

J thru RRT-2 1/2”-20 UNF-2A 40 to 80 lb. ft.

WARNING

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.

TO AVOID INJURY:

Use only the CM supplied suspension screws to attach the

suspension to the hoist and torque these screws to the recom-

mended seating torque as specified above.
