ABSTRACT:
The lifting device comprises a frame to which coupling members are provided to co-operate with attachment members located in the corners of the container. Each coupling member is capable of cooperating with an attachment member so that at a first reciprocal movement of the coupling member, coupling between the coupling member and the attachment member takes place, and so that at a further reciprocal movement of the coupling member the coupling member and the attachment member are uncoupled. The reciprocal movement is caused by the bottom end of the coupling member striking the bottom interior surface of the attachment member.
