摘要： The Invention relates to a coupling piece element for a Kenter shackle for anchor chains, which shackle comprises two half elements which can be coupled to one another and between which the coupling piece element can be inserted. The coupling piece element has a base body with at least one transverse borehole. Furthermore two securing bolts are provided, which are mounted in at least one transverse borehole in the base body and can be slidably moved outwards by means of at least one spreader element. The laterally protruding ends of the securing bolts are spherical or conical in shape. The base body has protrusions and/or recesses on its side surfaces facing the half elements for positive guidance on the half elements.

摘要： The invention relates to a rope sling shackle body for a heavy load rope sling shackle for suspending on a rope sling, at least comprising: —two mutually opposite end portions each with a through-opening for receiving a pin; a central arc which extends between the end portions and which has, at least in a rope receiving region, an arc bottom and arc flanks that are arranged on either side thereof and are spaced apart from one another, wherein the arc has a convexly rounded rope supporting face on its inner side at least in the rope receiving region, said rope supporting face extending from a top edge of one arc flank to the top edge of the respectively other arc flank; and at least one reinforcement rib, which is arranged between the arc flanks. The reinforcement rib is divided into two part-ribs via which in each case one arc flank is supported on the arc bottom, wherein there is a spacing between the part-ribs right down to the arc bottom.

摘要： The Invention relates to a Renter shackle for anchor chains, at least comprising two half elements which can be coupled to one another and a coupling piece element that can be introduced between the half-elements wherein the half elements each have an L-shaped or J-shaped configuration, wherein the external toothing having a plurality of parallel toothing planes is formed at the end of a short connection leg and wherein a receiving chamber is formed at the end of a long connection leg, having an internal toothing with a plurality of parallel toothing planes, into which the external toothing of the short connection leg engages, and wherein the connection legs are connected to one another via a curved clasp. In addition, the receiving chamber in the long leg is extended by means of a cavity above the end side of the external toothing of the short leg and/or above the uppermost toothing plane of the internal toothing pointing towards the clasp.

摘要： A heavy-duty shackle has a shackle body with two opposing end sections, each of which having a through-opening for receiving a bolt, which has a threaded section for a locknut at one end and a head at the other end, the head outer edge being non-circular. The through-openings are each surrounded by at least one nut bearing face, which is raised relative to a bearing face, directly surrounding the through-openings, for the head. An anti-rotation means for the bolt is formed in each case by a recessed head receptacle in the nut bearing face, the head outer edge being accommodated fully in the recess and being interlockingly held in place therein.

摘要： A block lock for round steel chains, having two half-elements which are displaceable relative to one another for opening and closing the block lock and which each have ends connected to one another via a longitudinal web, of which in each case one end has an insertion plug with a width reduced in relation to the longitudinal web and with retaining webs integrally formed on both sides, wherein at least two parallel retaining webs are arranged above one another on each side, and of which in each case the other end has a receiving pocket which serves to receive the insertion plug and on the two lateral inner flanks of which there are in each case formed at least two retaining grooves above one anotherto form a toothing by receiving the retaining webs. A central web extends inwardly from at least one longitudinal web.

The shackle body includes two opposite end portions each with a through-opening for receiving a bolt, a central arc which extends between the end portions and which has, at least in a rope receiving region, an arc bottom and arc flanks that are arranged on either side thereof and are spaced apart from one another. The central arc has a convexly rounded rope supporting face on its inner side at least in the rope receiving region that extends from a top edge of one arc flank to a top edge of the other arc flank. At least one reinforcement rib is arranged between the arc flanks and is divided into two partial ribs that support the arc flanks on the arc bottom. A spacing between the partial ribs extends down to the arc bottom.
