10. This set up is only required if the dock leveler is a
CLEAN PIT® model.
A. Burn or grind off welds where the maintenance
prop and hoist cylinder trunnion box are welded
to any steel imbedded in the pit.
B. Refer to the CLEAN PIT Installation Instruction
in the dock leveler owner’s/user’s manual. The
center angle and the front angle, which were
removed during the original installation, are to
be reinstalled.
NOTE: If the angles are supplied by Systems, Inc.,
the angles are shipped with the truck restraint pan
unit.
11. Set the leveler platform in the cross traffic position
(the lip fully folded, inside the lip keepers, and the
platform level with the dock floor).
12. Place a shipping band through the lip hinge and
around the front frame angle of the leveler. Secure
the banding. The banding is to secure the frame
angle to the platform when the leveler is removed
from the pit.
13. Burn or grind all welds where the top rear frame
angle of the dock leveler is welded to the rear pit
curb angle.
14. Remove Dock leveler from the pit using the lifting

the Pit Drawing.

hoist cylinder trunnion plates (S) which must be
imbedded into the pit floor as shown on the pit
drawing. If the existing dock leveler is a CLEAN
PIT model, it may be possible to reuse the existing
plate. On eight foot long dock levelers the plate is
an integral part of the truck restraint and a separate
plate is not required. See table on page 15
17. Install restraint pan into the pit. Insert spreader bar
into pan to reinforce during concrete pour. Make
sure the pan’s square and flush with the pit floor
and front dock wall.

and Hoist cylinder trunnion plates(s) that to be
imbedded in the pit floor in the plate is separate
from the pan.
19. Allow sufficient time for the concrete to set.

shipped separately).
