ABSTRACT:
A hoisting link device, comprising an upper link part (2) forming a closed loop dimensioned to be hung onto a lifting hook, and a lower chain connection part (3) to be connected to an end portion of a chain hanging down therefrom. The chain connection part comprises a fork-like lower end portion with two substantially parallel shanks (3a, 3b) defining a slot (4) therebetween, a bridge portion (5) connecting the two shanks to each other, an anchoring member (6) located below said bridge portion for securely anchoring an end link of said chain. An upper or central portion (4b) of the slot communicates with an insertion opening (4d) located at one lateral side of the device. The upper portion (4b) of the slot is adapted to accommodate a centrally located support link (102) of the chain end portion (3) so as to form a shortening loop between the centrally located link and the end link of the hoisting chain.
