INSTALLATION
E.O.D. Installation Instructions
Flush Mount - Weld On
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,
but complete weld across the top 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.
8. Installer must remove all welding slag, and repaint
welded areas.
9. Installer must adjust springs on all mechanical
Edge of Dock levelers to provide desired tension
for smooth operation. Stand in front of leveler, with
the unit raised and secured in the maintenance
position, loosen jam nut on the underside of the
linkage pin. To start allow about 3/4” to 1” of
threads between top of jam nut and linkage pin.
Using an open faced wrench, hold locknut on
inside of spring while tightening threaded bolt until
washer on top side of spring closes up tight to jam
nut. Test operation of unit. Further adjust spring
tension if needed by advancing jam nut toward
linkage pin and tightening threaded rod. After
desired unit operation is achieved, tighten jam
nut to outer washer on spring. Springs must be
adjusted alternately to have equal spring tension.
10. 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
NOTE
Pump should NOT be wired
while welding.
