Highest Truck Height T
We typically recommend using 55" for the T, since 55" is the maximum height for most trailers. On refrigerated or container trailers use 59".
Dock Height D
(You must measure this).
Height Differential (Maximum) H
H is equal to T minus D
Capacity Notes:
Stackers and other narrow aisle loaders should not be used on a dock board.
Paper roll clamp and multi-shift load add 5,000 pounds to the board capacity.
Capacity rated for single-shift operation at a 3 mile per hour maximum rate of travel.
For all railroad applications, we require a fully completed railboard worksheet.
Length
To determine the proper length of a dock board⁄plate, three items are required:
- Dock height (D)
- Height of highest truck (T)
- Type of loading equipment used
