Abstract: A rope sling shackle body for a heavy load rope sling shackle for suspending on a rope sling. 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.

Abstract: 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.

Abstract: Block lock (100) for round steel chains, having two half elements (10) which are displaceable relative to one another for opening and closing the block lock (100) and which each have ends connected to one another via a longitudinal web (10.1), of which in each case one end has an insertion plug (11) with a width reduced in relation to the longitudinal web and with retaining webs (13.1, 13.2) integrally formed on both sides, wherein at least two parallel retaining webs (13.1, 13.2) are arranged above one another on each side, and of which in each case the other end has a receiving pocket (12) which serves to receive the insertion plug (11) and on the two lateral inner flanks of which there are in each case formed at least two retaining grooves (14.1, 14.2) above one another to form a toothing by receiving the retaining webs (13.1, 13.2). A central web (10.2) extends inwardly from at least one longitudinal web (10.1). The insertion plug (11) widens, as seen in side view, from the longitudinal web (10.

Abstract: 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.
