INSTALLATION
A ramp mount-weld on used with a formed angle application
is used when dock edge is damaged, there is no dock steel
securely anchored into the concrete, and the dock height is
too low and the leveler must be installed above this height
to correct this situation.
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. Review and follow formed angle installation instructions
prior to leveler installation.
3. 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.
4. At the points marked to each side of center, measure
and mark points 7-3/4” below dock level less height the
unit is to be raised to locate bottom of base plate. This
will locate the top of the base plate X” above dock level.
5. Using a proper lifting device, raise and position the
leveler base plate to marked position. While holding
base plate tight against dock face, tack weld securely
to dock steel on left hand end of leveler. Check right
hand end of base plate, ensure that end is against
dock steel and that the bottom of the base plate is even
with the marks made previously. Tack right hand end
to dock steel. Support unit until final welding is ready
to complete.
6. Position bump blocks out approximately 5/8” out from
the edge of the inside flange of the bump block to the
end of the base plate. Position the top of the tread cover
plate on the bump blocks to be flush with the top of the
base plate. Tack weld bump blocks to dock steel.
7. Place steel ramp plate in position, flush with top
backside of base plate. Mark along full length of back
edge of ramp plate. Slide ramp plate forward over dock
leveler the width of bushing tool, approximately 2”.
8. Place bushing tool on marked line at each end of ramp
to ensure proper alignment at both ends, and tack weld
ramp plate to dock leveler to hold ramp plate in place
while bushing. A Skil Roto Hammer #736 or similar tool
is recommended.
9. Using the back edge of the ramp plate as a guide,
groove concrete approximately 3/4” deep by 2” wide,
and should be the entire length of ramp plate.
10. Break tack welds holding ramp in place, slide ramp
plate back into position with the top of the ramp plate
flush with the top of the base plate. Tack weld each end
and center of ramp plate to base plate.
11. 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 ¼” fillet weld all the way
around the nut. Cut off any portion of the anchor bolt
exposed through the 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.
12. Complete welding of tacked parts as follows:
A. Apply continuous weld across top of each bumper
and base plate to ramp plate. Skip welding is
acceptable to prevent warping, but complete weld
must be 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.
13. Installer must remove all welding slag, and repaint
welded areas.
14. 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.
15. 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.
16. 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.
