INSTALLATION
A flush mount bolt on application is used when there
is no steel on dock edge, and the dock height is
adequate. Additional steel ramp plate and bolting is
required with this type of installation.
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. At the points marked to each side of center,
measure and mark points 7-1/2” below dock level
(for 1/4” ramp plate) to locate position for bottom
of base plate. This position will place the top of the
base plate 1/4” above the dock floor. This position
will vary with ramp plate thickness.
4. Mark line connecting these points and position
support angles. Position angles as shown in
installation drawing provided. Mark center of
holes in each of the support angels.
5. At center marks, drill holes 5/8” dial. by 5” deep in
concrete. Install anchor bolts with washers through
support angles into holes in concrete. Tighten
bolts until support angles are secure. Follow
anchor manufacturers installation instructions for
proper installation.
6. Using a proper lifting device, raise and position
the leveler base plate to marked position, while
resting on the support angles. While holding base
plate tight against dock face, tack weld securely
to support angles.
7. Drill 5/8” dia. by 5” deep holes in concrete through
holes in base plate, and install anchor bolts with
washers and tighten securely.
8. 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 1/4” above dock level. Note that this placement
will vary with ramp plate thickness. Mark centers
of holes in bump block flanges.
9. Drill 5/8” dia. by 5” deep holes at center marks.
Reposition bump blocks, insert anchor bolts with
washers and tighten securely to dock face.
10. Place steel ramp plate in position, flush with top
backside of base plate. Mark along full length
of base edge of ramp plate. Slide ramp plate
forward over dock leveler the width of bushing
tool, approximately 2”.
11. 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.
12. 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 ramp
plate.
13. 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.
14. 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 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.
15. 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 bottom of base plate support angles
using a 1/4” fillet weld.
16. Installer must remove all welding slag, and
repaint welded ares.
17. Installer must adjust main springs on all
mechanical edge of dock levelers to provide
desired tension for smooth operation. Stand on
