A trailer for lifting and transporting a container comprises a frame having a hitch and supported on an axle on which a pair of wheels is mounted for rotation. A support arrangement is mounted on the axle for a tilting movement between an engaging position and a lifted position, and comprises two supports, each of the supports being provided with a bifurcated end portion adapted to engage projecting portions of the container. A winch is mounted on the frame and a line provided with a hook at its free end is attached to the winch; the hook is selectively attached to the support for moving the latter between the engaging and the lifted positions thereof whereby to lift the container, to the side of the container which faces the winch for holding the support arrangement and the container in their lifted positions, and to the side of the container facing away from the winch for tilting the container about the support arrangement in its lifted position for discharging the contents of the container.
