Dock Plate and Dock Board Measurement Guide

Dock Plate and Dock Board Measurement Guide

Select the right dockplate or dockboard with the assistance of our dock plate and dock board measurement guide. Choosing the correct SIZE and CAPACITY of equipment helps improve your dock operation. These factors are determined by length, width, height differential and capacity. Visit our Dock Plate and Dock Board Selection Guide for online assistance and to purchase dock boards and dock plates online.

Length

To determine the proper length of a dock board or dock plate three things are required:
• Dock Height (D)
• Height of the Highest Truck Bed (T)
• Type of Loading Equipment Used

Width

We recommend a minimum dockboard and dockplate width of 12″ to 18″ wider than the overall width of the vehicle or pallet used. For improved end loading efficiency, you may consider increasing the dock plate or dock board width.

 

 

 

Height Differential (H)

The height differential is determined by the highest truck height (T) minus the dock height (D). We recommend using 55″ for the highest truck height on freight trailers and 59″ on refrigerated or container trailers. T – D = H
