Abstract: U-frame truck comprising a prime mover and a trailer having a U-frame opened backwards and including two parallel side frames and a connecting middle-frame portion. Three hydraulic cylinders are adapted to directly co-operate with special brackets adapted on the container to be transported. In this way an inner frame is eliminated, which up to now always has been used for supporting the container. This means a saving of weight and costs.

Abstract: A transport vehicle for a slag pot comprising a vertically movable load surface and two lifting arms for the pot activated by hydraulic cylinders. The lifting arms are connected to a subframe positioned outside the load surface. The lifting arms are connected to the subframe immediately above ground support members. The subframe is pivotally connected to the forward portion of the load surface and rests on the rear portion of the load surface so that when the load surface is lowered, the ground support members are firmly placed against the ground.
