Make sure the platform is properly supported in the
raised position before entering the pit to finish weld
the shims.
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.
20. If present, weld the lip keeper shims ( P, page
14 ) to the front pit curb steel.
CA 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. Remove the Shipping Bar ( Q, page 14 ) by
grinding the tack welds that hold it in place during
transport.
22. Install the dock bumpers as required.
23. When all welding has been completed, paint all
the welds and shims.
24. Reinstall the air bellows if removed in step 16.
25. Proceed to “Install Control Panel” on Page 20.
