2. The latch is secured to the hook (upper and lower) by a rivet. To

remove the latch, it is necessary to remove the head of the rivet by

grinding or drilling. For replacement of the latch, refer to paragraph 4

of the Assembly Instructions.

ASSEMBLY

Consideration must be given to the following when assembling the hoist:

1. Assemble the brake components as shown below. The ratchet teeth

must face as shown and engage the pawl. Do not lubricate the brake

surfaces. The brake operates dry. Assemble handwheel to pinion

shaft and turn handwheel to seat brake components. Assemble the

pinion shaft nut to the shaft until the nut bottoms. Then back nut off at

least one but not more than two flats. Insert cotter pin and bend ends

to secure same.

TIMING

MARKS

2. The intermediate gears (622-8) have timing marks (letter “O” stamped

on one tooth). The gears must be assembled with these marks orien-

tated as shown below.

3. For proper operation, the correct number of rollers must be installed at the

rotating points of the liftwheel, intermediate gears, hook block sheave (3, 5 and

10 ton) and hoist hanger sheave (10 ton). Also, on the 3 and 5 ton units, the

correct number of bearing balls must be installed in the hook collar to retain the

hook and insure proper loading. Refer to Disassembly Instructions above for

the number of rollers at these locations. Applying grease, Molykote BR - 2 - S

(Dow Corning Corp.) or equal EP grease, to the rollers or bearing balls will

help hold them in position during assembly.

4. When assembling the latch to the hook, the end of the rivet must be peened

over. When peening over the rivet, only apply enough force to form the head

and retain the rivet. Excessive force will deform the latch and make the latch

inoperable.

REEVING LOAD CHAIN
A. 1/2, 1, 2, 3, 5 and 10 Ton Hoists

Attach approximately 20”(508mm) of soft wire to the loose end of the chain. Pass

the wire over the top of the liftwheel (622-13) and down between the liftwheel and the

chain guide (622-16). Position the chain so that the first, as well as the third, link

stands on edge with the weld away from the liftwheel and the second link lays flat on

the liftwheel. After the chain has been started, pull hand chain in the hoisting direc-

tion until about 2 feet (0.6M) of chain has passed over the liftwheel. The wire should

now be removed from the chain. Remove the cotter pin from the loose end pin (622-

15) and slide the loose end pin to the side into the gear housing, leaving approxi-

mately 1/2”(12.7mm) of the pin protruding from the geared side plate (622-5). Loop

the chain, making sure there are no twists, up to the loose end pin and slide the pin

B. 3 and 5 Ton Hoists

The load chain must have an odd number of links. After attaching the chain to the

loose end pin per above, operate in the hoisting direction until the load end of the

chain is approximately 5 feet (1.5M ) long. Run chain thru the hook block (first link

around the sheave must stand on edge) and up to the dead end block (622-26).

Secure chain to dead end block using the stud, nut and cotter pin. Refer to illustra-

tion below.

through the last link of the chain. Slide the loose end pin into hole in the handwheel side

plate (622-4). until the cotter pin hole is visible. Secure the loose end pin by reinstalling

the cotter pin and spreading the legs of the cotter pin.

WARNING

!

Failure to properly install the load chain between chain guide and liftwheel may

cause the chain to lift out of the liftwheel pockets and allow the load to drop.

TO AVOID INJURY:

Feed load chain between liftwheel and chain guide, as shown above, before

attaching it to the loose end pin.

10 Ton Hoist

The load chain must have an odd number of links. After attaching the chain to the

loose end pin per above, operate in the hoisting direction until the load end of the

chain is approximately 20 feet (6M) long. Run the chain thru the hook block (first

link around the sheave must stand on edge) around the first hook block sheave, up

around the hanger sheave, down around the second hook block sheave and up to

the hoist hanger. Secure the chain to the hoist hanger using the dead end stud, nut

and cotter pin (622-38). Refer to Illustration below.

WARNING

!

TO AVOID INJURY:

Check each stage of reeving the chain to be sure it has no twists.

On the 3, 5 and 10 ton units, twisted load chain will cause the chain to jam in

the liftwheel or sheave wheels and this may break the chain and allow the load

to drop.
