CARRIAGE

UPRIGHTS

hoist carriage is that the center of the

carriage load roller be at least 1/4

inch above the bottom of the inner

upright.

The uprights must be

collapsed and a rated load imposed

upon the load arms, when checking

roller position.

1. Place the truck on level ground with the uprights

vertical.

2. Fully extend the uprights making certain the

carriage stop does not contact the stop at the top of the

inner upright. A minimum clearance of 1/4 inch must be

maintained at this point with equal tension on the

chains. On free-lift models, this adjustment must be

made at the end of the free-lift or primary stroke.

CAUTION

After the above adjustment has been

made, never shorten the chains by

further adjustment.

3. Lower the carriage all the way down. If the load

arms are resting on the ground, make no further

adjustments. However, if the heels of the load arms do

not touch the ground, the chains may be lengthened

until the heels touch.

4. Periodic rechecks should be made to

compensate for wear and chain stretch by repeating

steps 1 through 3.

5. The carriage stops are not designed to

withstand the pressure exerted by the hoist cylinder.

These stops are merely to prevent the upright from

lowering if the load arms are still beneath a stacked

load.
