  • Patent number: 7261351
    Abstract: A spreader (1) for lifting a freight container (7, 17) comprises a frame (3, 4, 11) and two pairs of pickup elements (5). Each pair of pickup elements (5) are mounted at opposite ends of the frame (3, 4, 11) and the frame (3, 4, 11) is adjustable to adjust the separation of the two pairs of pickup elements (5). A detector (8) is movably mounted on the frame (3, 4, 11) for movement between a first position in which the detector (8) is closer to one pair of pickup elements (5) and a second position in which the detector (8) is closer to the other pair of pickup elements (5). The detector is adapted to detect a discontinuity in an object (7, 17) located below the spreader (1).
