Loading Dock Bumper Selection | Chalfant Dock Equipment


The Selection Of Loading Dock Bumpers

Dock bumpers are essential for protecting the loading dock from the backing impact force of a vehicle and absorb over 80% of the impact force. The impact force of a backing vehicle can be as much as 100,000 lb. of impact force and an improperly selected dock bumper could allow damage to the building, backing vehicle and even injure employees.

There are three types of bumpers to choose from; molded dock bumpers, laminated dock bumpers and steel face dock bumpers.

Molded dock bumpers provide an attractive look, but can be chipped or gouged.
Laminated dock bumpers provide greater wear capability than molded dock bumpers and can provide greater thickness, length and height.
Steel faced dock bumpers provide the greatest wear capabilities, normally four times greater than laminated dock bumper and are the best choice for a busy loading dock.

Dock Bumper Projection
For a typical level approach (0% grade) application, bumper projection should be specified at not less than 4". For decline/incline approach application total bumper projection should be as follows;

percentage of grade for dock bumpers

Note: You can either provide the above dock bumper projection with cantilever pit projection or use a fabricate steel build-out with dock bumper for the total projection required. If yard jockeys or spotted trailers are used, it is necessary to have the bumper projection required for the temporary raised nose of the trailer due to the greater grade it creates.

Dock Bumper Height
Special consideration should be given to the dock bumper height if air-ride equipped vehicles are to be serviced, due to the ability of the air-ride trailers 12" of vertical travel. For this type of application a vertical dock bumper should be considered with a minimum of 18" vertical height (Note: A greater vertical height may be required).
