18. All model levelers: Install shims at locations (B)
using the pyramid or stepped shimming method.
Both platform cylinder trunnions must be solidly
shimmed the entire length of the trunnion. Make
sure the trunnions are level from side-to-side as
well as from front-to-back.
19. Finish weld all shims using a fillet weld.
• Weld all shims within each shim stack to each
other, then weld the shim stack to the leveler
frame.
• Weld the front leveler frame shim stacks to the
front pit curb steel.
Make sure the platform is properly supported in the
raised position before entering the pit to finish weld
the shims. Failure to do this may result in serious
personal injury or death.
INSTALLATION
* For left/right orientation of dock leveler, see inside back cover of
this manual.
20. When all welding has been completed, paint all
the welds and shims.
NOTE: VH models are shipped with a front frame
section (C) installed. This temporary frame
holds the leveler frame at the correct
dimensions until the leveler is permanently
anchored into place. Only then should it be
removed.
There are four cap screws and nuts that
fasten the T- frame to the rest of the leveler
frame. Tack welds may also be used.
21. For all VH models, remove the Shipping Bar (C)
by grinding the tack welds that hold it in place
during transport. Paint after.
