ABSTRACT:
Load support apparatus comprising a housing on which a suspension device is mounted for movement between an operative load suspension position and an inoperative relaxed position. Also mounted on the housing is a holding bolt which is movable between a first position in which a load is supported by the holding bolt and a second position in which the load is released from the bolt. A displaceable locking bar is mounted in the housing for movement transversely of the displacement path of the holding bolt for engaging the bolt to lock the same in the position in which the load is supported by the holding bolt. A catch mechanism is displaceably mounted on the housing for locking the locking bar and a control mechanism responsive to the position of the suspension device operates to displace the catch mechanism to lock the locking bar in the position in which the holding bolt is locked when the suspension device is in its operative load suspension position.
