INSTALLATION
A flush mount weld on application is used when an 8”
wide (minimum) embed channel is securely anchored
into the concrete at the dock edge, and the dock
height is adequate.
Installation Steps:
1. Remove all existing bumper material and
protruding objects from dock edge. Clean and
sweep dock edge free of debris and flammable
chemicals before installing unit.
2. At chosen location for Edge-of-Dock leveler,
locate the center of space and mark a point half of
the base plate width to the left and right.
3. Using a proper lifting device, raise and position
leveler on dock face with the top of the base plate
being flush with the top of the embedded channel.
Position ends of base plate to match up with
marks made previously.
4. Tack weld base plate to dock steel on left hand
end of the leveler. Check right hand end of base
plate, ensure that end is against dock steel and
that the top of the base plate is still flush with the
top of the embedded channel. Tack right hand end
to dock steel.
5. Position bump blocks out approximately 5/8” from
the edge of the inside flange of the bump block
to the end of the base plate. This will allow for
vertical welding of both the base plate and the
bump block flange back to the dock steel. Top of
the bump block cover plate should be flush with
the top of the embed channel. Tack weld bump
blocks to dock steel.
6. Check the positioning of the base plate and the
bump blocks.
7. Complete welding of tacked parts as follows:
A. Apply a continuous weld across top
of each bumper and base plate to dock
steel. Skip welding is acceptable to prevent
warping,completed.
B. Weld vertically along each end of base plate
and on both inboard and outboard flanges of
bump blocks.
C. Fully plug weld all holes in base plate.
8. Installer must remove all welding slag, and repaint
welded areas.
9. Drill 5/8” dia. by 5” deep holes in concrete through
holes in lower cylinder mount, and install anchor
bolts with washers and tighten securely.
10. Field mount control box to inside wall. Field wire
control box and hydraulic power unit per electrical
schematic(s) provided. Read and comply with all
local electrical codes.
11. Before install is complete, installer must make a
final operational check of dock leveler to verify
all phases of install are correct. Installer must
complete, sign and return the Installation Checklist
upon completion. Reference page 24.
