INSTALLATION
A ramp mount requiring a face plate application is used
when there is no existing dock steel and the concrete at
the dock edge has been damaged. The dock height can
be low, high, or adequate for this application, however,
the face plate and ramp plate are required to rebuild the
damaged concrete edge.
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 the face plate, locate the center
of space and mark a point half of the face plate width
to the left and right.
3. Using a proper lifting device, raise and position the
face plate to marked position, and push face plate
against dock face.
4. Top of face plate should be flush with the top of dock
floor. Mark center of holes in face plate into dock face.
Drill 5/8” dia. by 5” holes into dock face. Install anchor
bolts with washers per manufacturers specifications
and tighten securely.
5. Place ramp plate to match each end of the face plate.
Leading (forward) edge of ramp plate should be flush
with dock face.
6. Mark along full length of back edge of ramp plate. Slide
ramp forward the width of bushing tool, approximately
2”.
7. Place bushing tool on marked line at each end of
ramp to ensure proper alignment at both ends. A Skil
Roto Hammer #736 or similar tool is recommended.
8. Tack weld ramp to face plate on each end to secure
in place.
9. Using the back edge of the ramp plate as a guide,
groove concrete approximately 5/8” deep by 2” wide,
and should be the entire length of the lamp plate.
10. Break tack welds and slide ramp back until forward
edge is flush with dock face. Tack weld ramp on each
end and center to face plate. Drill 5/8” dia. by 5” deep
holes through ramp plate at back edge. Install anchor
bolts per manufacturers specifications, and tighten
securely. Weld anchor bolt nuts to ramp plate using a
1/4” fillet weld all the way around the nut. Cut off any
portion of the anchor bolt exposed through he nut,
and plug weld around the top of the nut to the anchor
bolt. Ensure the top of the nuts are well rounded for
smooth rollover.
11. Apply a continuous fillet weld at the created joint
between the face plate and ramp. Skip welding should
be the proper method used to avoid warping, and a
complete weld must be achieved.
