Dock Planning & Design
Dock Access
Apron Space
The configuration of the area required to maneuver and position trailers into place is called the apron space. Planning apron space requires recognizing trailer movement and the amount of room it takes to achieve that movement. Traffic flow and vehicle length are key factors for consideration (ie. a truck with an overall length of 65' requires a minimum apron space of 135’).
Landing Strip
If the area is to be surfaced with asphalt, a concrete landing strip must be poured. In warm temperatures, the landing strip will prevent the trailer's landing gear from sinking into the asphalt when spotted. Typical position of semi-truck landing gear is 120" behind the nose of the trailer. Gravel-covered apron space should be avoided because it creates uneven, unsafe conditions.
Waiting Area
Unless docks are designed to handle peak loads, provision must be made for a truck waiting area. This should be placed
so that the trucks in this area do not interfere with trucks maneuvering into or pulling away from the dock.
Pavement Surfaces
These surfaces should be specified to be evenly laid and structurally sound to support heavy wheel loads. All roadway surfaces
should be slightly crowned and properly equipped with drainage outlets.
