Mechanical Transport (B Vehicles) - Trailers


Throughout its life the RAF has used more motor vehicles then it has aircraft.  The term MT mean Mechanical Transport rather then Motor Transport as some of the earliest vehicles used were steam powered.  Much of the RAF's early MT equipment was taken over form the RFC and RNAS and much of this equipment continued to be used into the 1920s and even 1930s but in the 1920s it began to acquire its own equipment directly.

This list has been broken down into groups as shown above but does not claim to be exhaustive and further research is being undertaken.

W1 = Weight with vehicle equipment, but without load. W2 = Weight with vehicle equipment and load. L = Length. W = Width. H = Height. H(max) = Maximum Height. H(min) = Minimum Height. ST(max) - Maximum Shipping Tonnage. ST(min) = Minimum Shipping Tonnage, WB = Wheelbase.  GC = Ground Clearance

Units of measurements are those used at the time the vehicles were in service.

1 kilogram (kg) = 2.2 pounds (lbs)

112 lbs = 1 Hundredweight (cwt)

1 Ton = 20 cwt

25.4 millimetres (mm) = 1 inch (in)

12 inches = 1 foot (ft)
