ABSTRACT:
A support is forced to be extended between a longitudinal member of a hull block clamped between a movable jaw and a fixed jaw on the one hand and another longitudinal member located adjacent to the first mentioned longitudinal member so that the load exerted to the clamping device when the hull block is lifted as well as the reaction force exerted to the support may force the movable jaw against the longitudinal member to firmly clamp it between the movable and fixed jaws. The longitudinal member is so firmly clamped between the movable and fixed jaws that it is not released even when the hull block is lifted in the vertical position.
