Adjustment
• Inspect all welds for cracks and signs of metal fatigue, especially at the hinge.
The springs are under high tension. If quickly released or pried loose, the springs can
cause equipment damage and/or serious injury.
o Springs should not be corroded or rusty. Replace as necessary.
o Springs ends should be secured at either end.
• Inspect the Dock Leveler operation. If adjustments are needed, see below.
• If paint has chipped, prepare the surface and paint.
RR Models with the ES Option:
If the pull chains, safety legs and safety leg’s springs are hindered with debris or have
excessive wear, the Dock Leveler will lower and bottom out during usage. Any persons
or equipment on the Dock Leveler may slide off and fall causing injury and/or equipment
damage.
• Inspect the linkage operation.
o The return spring on the safety legs should be functioning and securely connected.
o The D-rings guiding the Release Pull Chain should be greased. The chain’s travel should be
unobstructed.
Adjusting Spring Tension
Deck Lifting Mechanism
When adjusting the spring tension, stretch the springs to the same length. This will unify the spring force
acting on the lifting mechanism. The lifting motion will be more uniform.
The deck’s lifting speed impacts the lip extension. The deck’s momentum provides the extra energy to
extend the Lip outward. Hence, if the lifting speed is too slow, the lip will not extend.
Uniformly increase the spring force by uniformly lengthening each springs length until the lip extends.
Lip Extending Mechanism
Pulling the lip chain engages the lip’s Counterbalance Spring and rotates the lip outward. The
appropriate compression in the spring is important for this actuation. The spring’s force should be
maximized while still having the lip fall back to the vertical position. Too much spring force and the lip will
not return to its stowed, vertical position.
Perform the following sequence of steps until the spring force is maximized and the lip still returns to its
stowed, vertical position.
Adjustment Sequence
1. Grab the lip end and manually extend lip.
2. Release the lip.
3. If it falls to the vertical position, tighten spring nut clockwise.
