  • Patent number: 7014270
    Abstract: A tail extension (1) adapted to be pivotally attached (2) to a load carrying container (3). Tail (1) pivots between a first position substantially outwards from a floor of the container, and a second position upwardly inclined relative to said floor. Tail (1) may be formed as one or a plurality of sections which move individually or cooperatively. Tail (1) may be pivotally connected (2) adjacent the floor of container (3) by a hinge allowing free movement and/or may be displaced by a drive means (e.g. hydraulic, mechanical, pneumatic). By tail (1) being able to pivot when contracting the ground, tail (1) and container (3) are not going to be subjected to undue forces which may damage tail (1) or container (3). When being transported, tail (1) acts as an extension to improve the load carrying capacity of the container by extending outwardly, or, can be displaced upwardly by a drive means to form a rear wall on the container.
