A connection device for coupling a load to a lifting lug with a support bolt which is rotatable in a through-opening of a ring holder. The support bolt has a threaded shaft and a bolt head which protrudes radially, and which can also be rotated therewith relative to the lifting lug. The ring holder is covered at the lower side thereof by an end flange at the lower end of a sleeve which is releasably secured to the support bolt by tension in an axial direction. The ring holder has at least one locking member for the bolt head which blocks the bolt head from rotation in a locking position and which is not in engagement with the bolt head in an initial position. The support bolt is supported in the through-opening of the ring holder with a ball bearing, and the lifting lug is an open ring.

Connection device for coupling a load to a lifting lug by means of a support bolt

A ring nut. A suspension ring includes a base having a sleeve with a threaded bore that is rotatably mounted in a penetration opening. The sleeve is supported by a circumferential annular collar at a bearing surface, surrounding the penetration opening, that is on an exterior at the end of the sleeve facing away from the underside of the base with a non-rotationally symmetrical head profile. The sleeve protrudes at the lower end into a central opening of a disc resting against the underside of the base and is connected thereto in a rotationally fixed manner but does not project at the underside from the disc. A locking member on the base can be brought into a locking position, cooperating with the head profile for locking in the rotational direction, and into a neutral position where the head profile is released in the direction of rotation.

Ring nut

An eye bolt, comprising a lifting eye and a supporting bolt, wherein the supporting bolt sits, rotatable, in an insertion opening of the lifting eye and comprises, a threaded shaft and a bolt head. The supporting bolt protrudes radially from the lifting eye and is supported by an underside of the lifting eye, on a bearing surface formed on the lifting eye and running around the insertion opening. The eye bolt further comprises at least one locking member which can be brought into engagement with the bolt head and by means of which, in a locking position of same, the bolt head can be rotationally blocked vis-&#xe0;-vis the lifting eye. The at least one locking member is further attached to the lifting eye radially next to the bolt head and is secured there, wherein the at least one locking member can be brought into a starting position, in which it is not engaged with the bolt head, and also into the locking position rotationally blocking the supporting bolt relative to the lifting eye.
