FLOAT SPRING and CABLE ROLLER REPLACEMENT
1) Raise dock leveler and position
maintenance strut and traffic barriers as
required for safety.

The hold down cable will now be
handled. Wire wound cables become
frayed with use and must be handled
with care. Use leather gloves or similar
protection. Enter pit area and remove
hold down box cover, counterweight and
lock roller.
3) See Figure 28 for illustration of hold
down box system, float spring and cable
rollers.
4)
The rewind spring is applying tension to
wind the hold down cable into the hold
down box, grip the cable firmly and
proceed carefully. Pull the cable out of
the box slowly, hand over hand, until all
cable is unwound from the rewind wheel
or the rewind spring is fully tensioned
and will allow no further rotation of the
rewind wheel. Lock the rewind wheel in
this position with vice-grips or other
suitable clamping device. The rewind
spring is now under full tension, work
with appropriate caution. Remove and
replace float spring and / or cable rollers
as required. See Figure 29.
5) Feed the loose cable end through lower
and upper cable rollers and through the
front eye of the float spring, Loop cable
back over thimble and install the cable
clamp in its original position. Tighten
clamp securely. See Figure 30.
