摘要： An attachment point with a lower part having connection means for connecting the attachment point to an object to be handled, and with an upper part which is rotatable relative to the lower part and connected thereto. The upper part has a connection element for connecting a lifting, attachment or lashing means. The upper part has a bearing surface that tapers conically in the axial direction, and the lower part has a bearing surface that tapers conically in the same direction. Roller bearing bodies are arranged between the two bearing surfaces. Each roller bearing body has a form defined by an axis of rotation thereof and a rotationally symmetrical lateral surface. The axes of rotation of the roller bearing bodies are aligned in the direction of the conical taper of the bearing surfaces and angled relative to the axis of rotation of the upper part relative to the lower part.

摘要： A chain having a chain link with two legs and two bows connecting the legs together, the bows extending in the bow extension direction between the two legs, wherein an end face of at least one bow, which faces outwards in the pitch direction of the chain link, has two pressure portions spaced apart from one another in the bow extension direction and an intermediate portion connecting the pressure portions, wherein the pressure portions each provide a contact surface between the chain link and a corresponding chain pocket of a chain wheel for introducing a force into the chain, and wherein the end face of the bow is convexly curved in the bow extension direction in the pressure portions and the end face of the bow has, at least in portions in the intermediate portion, a smaller radius of curvature than in the pressure portions.
