Blue Giant dock bumpers are available in several heights, 10", 13", 18", 20" and 30", depending on the specific style and model. Docks servicing air-ride-trailers should consider the vertical height of the loading dock bumper closely, for the maximum raised and lower height for air-ride-trailers arriving at the dock. When air is released from suspension system, of an air-ride-trailer, the bed can plunge downward causing the trailer to loose contact with the loading dock bumpers. The result can cause the trailer to become a "giant pry-bar" which can damage the dock and short vertical height dock bumpers.

Raised bumper brackets should be consider when a truck/trailer bed height is higher than dock height. Applying raised bumper brackets can prevent damage to the dock equipment and structural damage to the building wall.

Steel face plate bumpers are used for high frequency/heavy impact applications, where yard jockey trucks are used for trailer positioning and/or when air-ride-trailers are encountered. A steel face plate on your loading dock bumper, offers protection against unusual wear, provides smooth transition for trailer travel during loading/unloading and greater life for your dock bumpers - which can reduce the frequency and cost of replacing dock bumpers in the future.
