6.
Locate and weld Hydraulic Cylinder upper
mounting bracket to the dockleveler ramp plate
as shown.
(See Figure 14).
7.
With the dockleveler in the rest position, adjust
the hydraulic cylinder rod eye so that the rod eye
hole center is about 3
-
1/2” from the unthreaded
portion of the extension rod. Then extend the
hydraulic cylinder until the rod eye lines up with
the hole in the upper mounting bracket. Verify
that the EOD ramp plate is resting on the
mounting plate gussets.
(See Figure 15).
Do not use fingers to check alignment, use bolt
supplied. A pinch point could result in serious
injury.
If electrical connections are completed prior to
hydraulic cylinder adjustment, disconnect and
lockout until all work is done. Failure to follow
these safety practices could result in death or
serious injury.
The “L” dimension (or minimum amount of
exposed extension rod with the dockleveler in
it’s rest position.) must be greater than 1
-
3/4”.
Failure to do so will cause the hydraulic cylinder
to bottom out under load resulting in permanent
damage to the hydraulic cylinder.
8.
Assemble and tighten 5/8” hex bolt and lock nut
supplied. Then tighten the rod eye nut to secure
rod eye.
(See Figure 15).
9.
Mount control box per local codes. Control box
should be mounted inside the building, and give
the operator a clear view of the dock during use.
The control box must be mounted where the
operator has a complete and clear view of the dock
and EOD during operation. Failure to mount the
Control Box in the correct area could result in
personal injury or death.
