Extra Thick Dock Bumpers
Intended for use on loading docks with decline approaches. The extra thick bumper series is the only solution to protect your facility walls from trailers docked at slopes greater than 2%.
Need help finding a Dock Bumper?
The typical projection for a dock bumper is 4.5”. While this is ideal for a dock with a level approach & no obstructions, loading docks with declines require thicker bumpers to maintain a minimum gap of 4" between the wall and trailer.
Increasing Thickness for Decline Approaches
For decline approaches, add 1" of thickness for every percent of slope over 2%. This increase is additional to the standard 4.5" depth required for level dock approaches.
Pit Leveler Bumpers
Pit Levelers require, at minimum, 8" of lip inside the trailer. Increasing dock bumper projection beyond 6" may require cantilevering of the pit leveler to ensure the lip operates in a safe manner.
Depths Greater than 10.5"
The majority of dock boards with legs or 2 pin models are designed to bridge gaps up to 11". When considering your dock bumper depth keep in mind gaps greater than 11" are unsafe for boards without 4 pins.
Note: When measuring slope keep in mind the goal is to measure the slope of the trailer. For the majority of applications this would require a slope measurement from 50'.
Uses / Applications
Material / Thickness
Dock bumper depth is generally determined by the degree of slope your trailer sits at. For every percent of slope over 1% we would add an inch of depth to the standard 4.5" depth. For example a trailer with a 5% slope would require a 9" or 10.5" deep bumper.
