A system for mounting a head frame to a spreader includes a sheave assembly connecting the head frame to a crane so as to permit the lowering of the head frame, mutually cooperating engagement devices for coupling the head frame and the spreader, an actuator arranged to connect mutually engageable transmission connectors on the head frame and spreader, and a registration device for registering the coupling of the head frame and the spreader. The registration device is arranged to prevent engagement of the transmission connector until the head frame and spreader are coupled.

System and method for the coupling of a head frame

A flipper assembly for guiding a spreader to engage a container is provided, the flipper assembly comprising a flipper hingedly mounted to the spreader, said flipper moveable between an open and closed position about said mounting; a motor mounted to the spreader distal from said flipper; a spacing assembly located between the motor and the hinged mounting of the flipper, wherein said spacing assembly is capable of transmitting a torque from the motor to the hinged mounting so as to move the flipper between the closed and open positions.

Spreader with flipper arm drive

A head block assembly () comprising a first head block () having a first pair of cable engaging sheaves (); a second head block () having a second pair of cable engaging sheaves (); a separation device () mounted intermediate the first and second head blocks (), for effecting relative transverse movement of said head blocks; wherein the first pair of sheaves () are selectively disengagable from the first head block (), and selectively engagable with the second head block ().

Method and apparatus for effecting relative movement of containers

A latch mechanism () includes a latch member () movable between a release position and a latched position, an operating member () movably coupled to the latch member (), the operating member () being movable between a first position and a second position and the latch member () being in the release position when the operating member () is in the first position and the latch member () being in the latched position when the operating member () is in the second position. An actuating member () movable from a first position to a second position. Movement of the actuating member () from the first position to the second position causing the operating member () to move from the first position to the second position. A lock member () locks the operating member () in the second position and the lock member () moves from the disengaged position to the engaged position when the operating member () is moved from the first position to the second position. A release member () is movable between a first and a second position, movement of the release member from the first position to the second position, when the lock member is in the engaged position, causing the lock member to move from the engaged to the disengaged position to permit the operating member to move from the second position to the first position. The actuating member () and the operating member () are movably mounted on each other.
