A flip axle is a complete axle assembly that can be entirely removed from the trailer when it isn’t required. It is attached to the rear of a trailer by hinge plates and pins, allowing for it to be deployed and bear weight or be retracted and rest on top of the trailer bed when rotated up to 180 degrees.  Depending on the State that the trailer is in, the additional axle can be used to spread out the load and ensure that all regulations on per axle weight limits are met. In addition, the flip axle adds flexibility and capability to a fleet’s existing trailers, giving them the option of being used for heavier loads. A flip axle can also simply better distribute the weight of a load, helping to extend the trailer’s life.
