ABSTRACT:
A trailer for use as an ice fishing house or for transporting a load from one area to another has a frame and a load bearing platform attached to the frame which is capable of being moved from a travel position to a ground level position. A lifting mechanism is located on each side of the trailer and made a part of the rubber torsion stub axle assembly connected to the trailer frame with the lifting mechanisms being operated by arm and handle assemblies attached to rubber torsion stub axles. When the arm and handle assemblies are rotated to a vertical position, the trailer frame is lowered to the ground level and when the arm and handle assemblies are rotated to a horizontal position, the trailer frame is raised to the travel position. Two securing means are used on each lifting mechanism to secure the frame in the travel position.
