Abstract
A invention relates to a chain shackle for fastening a hoist chain of a chain hoist to a hoisting member or the chain hoist. The chain shackle includes two identical shackle halves installable against each other to work together in such a manner that they form between them a first space for one chain loop or chain loop half of the hoist chain to lock it against the hoisting direction or force. The first space is open in a first direction in the longitudinal direction of the chain shackle. A second space is connected to the first space and intended for a second hoist chain loop that is coupled with the first chain loop or is to be coupled with a chain loop half. The second space is open in both longitudinal directions of the hoist chain.

A chain shackle for fastening a hoist chain of a chain hoist to a hoisting member or the chain hoist, the hoist chain comprising chain loops fastened to each other with the planes formed by the adjacent chain loops mainly at a 90° angle to each other, wherein the chain shackle comprises two identical shackle halves installable against each other to work together in the longitudinal direction of the halves and the hoist chain in such a manner that they form between them a first space for one chain loop or chain loop half of the hoist chain to lock it against the hoisting direction or force, the first space being open in a first direction in the longitudinal direction of the chain shackle, and a second space communicating with the first space and intended for a second hoist chain loop of the hoist chain that is coupled with the first chain loop or is to be coupled with a chain loop half, the second space being open in both longitudinal directions of the hoist chain and turned 90° in relation to the first space about the longitudinal direction of the hoist chain, wherein it also comprises a sleeve-like locking nut, the inside of which forms a space corresponding to the outline of the chain shackle for bringing the chain shackle and its shackle halves into cooperation, and the outer surface of which has threads for fastening the chain shackle that is supported against the locking nut to the fastening site.
