ABSTRACT:
The invention relates to a lift assembly for handling a heavy goods container such as used in marine cargo and highway transportation. The lift assembly includes two right hand sub-assemblies and two left hand sub-assemblies, which, when connected together, form an open space frame adapted to receive the container. Quick release connectors are provided for hingedly connecting the sub-assemblies together. There are links, connected to the sub-assemblies and adapted to cooperate with the container, for supporting the container above the ground. The lift assembly includes lifters for raising and lowering each right hand and left hand sub-assembly, thereby raising and lowering the container as required. By differentially adjusting the lifters, the container may be moved (swayed) sideways and fore and aft to position or romove accurately the container on or off a transportation vehicle. The lift assembly also includes locators for locating the container relative to the lift assembly, which concurrently stablizes the lift assembly against swaying. Preferably, the lift assembly includes weight monitors, connected to the lifters, for monitoring the weight of the container.
