摘要： A lifting hook comprising a suspension part (1) fitted with a suspension shaft (7) which supports a hook part (5) provided with a slot (6). A safety latch (11) is pivotally journalled in the hook part. In a raised position, the safety latch keeps the suspension shaft distanced from an upper end portion (32) of the slot by engaging contact surfaces (16, 17) of the suspension part. When the safety latch is swung down, the suspension shaft moves into said end portion, whereby the safety latch is locked. The hook part (5) can be arranged, when being lowered into contact with the load or another surface and thereupon lifted again, to perform a turning movement into an upside down position during which the safety latch is opened and the load is released. The turning movement is caused by a displacement of the suspension shaft (7) and the hook part (5) in relation to each other along the slot (6), which results in a displacement of the centre of gravity of the hook part.
