Calculate Axle Weights with Full Turntable Drawbar Trailer

Calculate Axle Weights with Full Turntable Drawbar Trailer 1024 451 TruckScience

Now you can use our Axle Weight Calculator to calculate axle weights and maximum payload for a straight truck with Full Trailer.  You might also know this as a rigid truck with Drawbar trailer, or even Dog trailer, if you’re in Australia.

With the update to the app today, you can add a hitch to a straight truck chassis, and couple a full trailer to the combination, then compare axle weights with manufacturer or regulation limits, or calculate maximum payload achievable with the combination.

Which Hitch?

Your choice of hitch may depend on the terrain on which the vehicle will travel, or on whether your payload is limited by weight or space.

Rear-Mount Hitch


A rear-mount hitch will achieve greater ground clearance, so is a popular choice for a vehicle that will travel on uneven terrain.

Underslung Hitch

An underslung hitch allows for a more closely-coupled trailer, that is, the gap between the truck and trailer is smaller, giving a swing clearance advantage. The overall length saving may also provide a payload gain, for instance allowing an extra row of pallets to be loaded.
