Installing the Edge of Dock Leveler

An EOD has three major plate sections:

• Base Plate that anchors to the dock.
• Center Plate that rest horizontally on the gussets.
• Lip Plate that hangs pendent at the front of the EOD between the bumpers.

1. When lifting the EOD into position for welding, use a properly sized chain or lifting strap.
2. Lift and swing the EOD into position at the dock face.
   • The normal weight of an EOD without the bumpers will be approximately 400-500 lbs. with larger and heavier capacity units weighing 600-700 lbs.
3. Hang the unit so that the base plate is facing the dock.
4. Position the top edge of the Base Plate ¼” below the top edge of the dock steel whether it is embedded steel or a surface mounted Approach Plate.
   • The ¼” dimension is an average since the Base Plate may be slightly bowed up at each end due to the heat from the factory welding of the hinge tubes to the plate.
5. Press the Base Plate tight against the dock steel and tack’ weld at each end and once in the middle.
   • This ¼” below dock positioning will allow for a solid “fillit weld” along the top edge of the Base Plate.
   • It also lowers the rear hinge tubes in relation to floor level, reducing the slight bump created by the rear hinge.
6. Now tack weld the bumper housings in place at floor level.
   • Allow approximately ½” gap between the ends of the base plate and the bumper flanges.
7. Fully weld the EOD and the bump blocks to available steel.
   • If welding to an 8” channel, use the pre-punched holes in the Base Plate for securing the bottom edge of the Base Plate to the steel. No bolts are required in the lower two holes in the bumper housings even though they are below the 8” channel.
   • If the steel edge is less than an 8” channel and the holes in the base plate as well as the holes in the bumper housings fall below available steel, these holes must be bolted for proper installation. Minimum bolt size should be 5/8” x 4”.

Proper Adjustment:

Most EODs are furnished with either torsion spring or extension spring lift assist. Manufacturers normally ship EODs without the springs adjusted to reduce the risk of injury to installation personnel. To maximize the ease of lifting, tighten the springs until the EOD center plate will float about 1” off the gussets when the Lip Plate is dropped from a horizontal position. As the Lip Plate swings in against the gussets, the center plate should raise slightly.

Caution: Do not over tighten as this may cause the EOD to kick up under a forklift while exiting the trailer especially when deployed on a trailer that is several inches above the dock.
