    摘要： The present invention is a safety hook (12, 12′) having a wire spring latch (26, 26′). The wire spring latch (26, 26′) is a wire loop pawl. The safety hook (12, 12′) is made of a heavy gauge wire form material, which is preferably bent only to form first and second ends (14, 14′, 16, 16′), a chain link securing end (14, 14′) and a hook opening end (16, 16′), respectively. The wire loop pawl (26, 26′) is preferably a rod of elastically deformable material, bent to form an open loop (28, 28′) and bent-over ends (32, 32′, 34, 34′) about which the pawl (26, 26′) pivots with respect to the body (12, 12″) of the safety hook (10, 10′) when the latch (26, 26′) is deformed and forced away from a distal end (38, 38′) of the hook opening end (16, 16′) of the safety hook (10, 10′). The bent over ends (32, 32′, 34, 34′) of the wire loop pawl (26, 26′) are not coaxial. The wire loop pawl (26, 26′) may be deformed in such a way as to open the safety hook (10, 10′), but the latch (26, 26′) is heavily spring biased up against an inside (37, 37′) of the distal end (38, 38′) of the safety hook (10, 10′).

    摘要： The invention proposes an apparatus characterised by its versatility for continuously adjusting the length of a lifting sling (H) designed to carry a load (F), which is provided with a U-shaped clamp (2) having a bearing (6, 7) for a swivel axis (8) constructed at each of its legs (4, 5) projecting from the ends of a central part (3) of the clamp (2), a load-lifting element (13) secured to the clamp (2) to which the load.(F) can be attached, and a clamping element (16) supported on the swivel axis (8), which has two side legs (14, 15) running parallel to one another at a distance, which each have their one free end coupled to the swivel axis (8), an end cross-piece (17) formed at the other end of at least one side leg (14) which covers the distance between the side legs (14, 15), and a centre cross-piece (21) arranged between the end cross-piece (17) and the swivel axis (8).
