  • Patent number: 6431379
    Abstract: An automated load handling apparatus is provided for handling loads fastened to a spreader having corners and a load suspension mechanism. The load handling apparatus includes a lifting yoke having a horizontal supporting framework that may be suspended at its comers to the spreader, four axially displaceable pendulum supports arranged between the lifting yoke and the spreader for supporting the lifting yoke, a rigid load guide including a lifting mechanism having ropes corresponding to comers of the lifting yoke that may be fastened to the load suspension mechanism of the spreader, and a cylinder pair 7.1, 7.2 arranged toward an end of the lifting yoke. The cylinder pair 7.1, 7.2 provides torque support to the lifting yoke relative to the load guide and is capable of displacing and/or pivoting the lifting yoke relative to the load guide. A sensor mechanism is arranged in the cylinder pair for detecting relative orientation of the lifting yoke relative to the spreader and/or the load guide.
