ABSTRACT:
The multipurpose spreader attachment includes in a first preferred embodiment projections on an underside that define sockets to be engaged with complimentary bosses located on the upper surface of a cargo cage. A latching mechanism is provided to effect a locked arrangement between the spreader and the cargo cage to couple to the cargo cage reliably and securely. The cargo cage is adapted to accommodate both the heavy lifting equipment as well as the pallets of goods to be unloaded, such that the need to change riggings for moving the fork lift and moving the cargo is eliminated. Moreover, the multipurpose spreader is equipped with cables that preferably include actuable hooks that suspend from the spreader and can be opened and closed via an actuator on the spreader. The hooks are adapted to cooperate with connectors such as rings on the preslung pallets, allowing the crane and multipurpose spreader to lift the preslung pallets in addition to the cargo cages. When the preslung pallets are moved to their destination, the actuated hooks are released from the connectors via the actuator and the actuated hooks are stowed within the spreader framework so as to avoid interference with the other loading/unloading operations.
