Abstract
Abstract A carrier for the loading and unloading of elongated freight containers includes a U-shaped body consisting of beams forming an inner space corresponding to the size of the container, and hydraulic means gripping and lifting the container. The U-shaped body has four wheels at its corners with hydraulic motors and steering means, an engine and a hydraulic pump driven by the engine and operatively connected with the hydraulic wheel motors, the steering means and the hydraulic gripping and lifting means. The operative connections of the pump include control means.

A carrier for loading and unloading elongated freight containers, comprising a U-shaped body consisting of an elongated beam and two beams extending at right angles to the firstmentioned beam and connected to the ends thereof, said beams enclosing a space the length of which is substantially equal to the length of the container to be transported and the breadth of which is substantially equal to the width of said container, hydraulic gripping and lifting means carried by said body for gripping said container at its top corners and lifting it into a transporting position and to a height which is at least equal to the height of one container from its base when containers are to be stacked one upon the other, four wheels carried by the corners of said body, separate hydraulic motors connected with said wheels, means connected with said motors and said wheels for steering said wheels and changing their direction to the extent of 90*, an engine carried by said body, at least one hydraulic pump driven by said engine means supplying pressure fluid from said pump to said hydraulic motors for the wheels, to said hydraulic gripping and lifting means and to said means steering the wheels and changing their direction, and electrohydraulic control means connected with pressure fluid supplying means for controlling the gripping and releasing of the container, for controlling the lifting and lowering of the container, for accelerating and decelerating the speed of travel of the carrier and changing its direction of travel and for steering the wheels and changing their direction, wherein said gripping means are displaceable relatively to the lifting means longitudinally and laterally to the container.
