Abstract: A method of providing a safety measure when lifting a load (13) by means of a lifting sling (10) with at least two legs (10a, 10b) connected to the load (13) at two connection points (14a, 14b). Instead of checking the inclinational angle of each sling leg, in addition to observing the working load limit (WLL), the user can check that the horizontal distance between the connection points does not exceed a Horizontal Length Limit (HLL).

Abstract: A coupling link (100) to be interconnected between a hoisting device and a shortenable hoisting chain (54,55,56) is provided. The coupling link is elongated and comprises a connecting portion (110) in the form of a loop for connection to the hoisting device and an anchoring portion (150) for anchoring of an end link (51) of the hoisting chain. A selected link, namely a support link (55), of the hoisting chain is inserted in a support slot (132) between two support shanks (131a, 131b) of the coupling link, and a hoisting chain link adjoining the support link, namely an engagement link (54), will make contact, at an end portion thereof, with corresponding seating surfaces (133a, 133b). The loop portion (110) defines a free internal space (111), which is dimensioned to enable pulling through the hoisting chain (50) for adjustment of its effective length and which directly adjoins the support slot (132).

Abstract: A coupling device for coupling a hoisting member, such as a hook (1), to a flexible hoisting strap (7). The device includes a coupling part (4) having a straight bar portion (6) with which the strap (7) engages. The device also includes a hoisting body part, such as a hook body (2) to be coupled to a hoisting device or a load. An entrance opening (10) is located opposite to the straight bar portion (6) and is dimensioned to snugly receive the narrowest dimension of the hoisting strap (7).

Abstract: A chain coupling assembly comprising a closed ring member (1) to be coupled to a hoist, e.g. a lifting hook, and at least one chain coupling or shortening member (5) to be coupled to a hoisting chain. A portion (1e) of the ring member is flattened so as to fit snugly into an insertion opening (6) leading to a hook portion (3) of the chain coupling or shortening member (5). Hereby, the closed ring member (1) and the chain coupling or shortening member (5) can be securely connected directly to each other.

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.

Abstract: A lifting hook with a hook body (110) and a shank (112), which has a slot (116) with an anchoring member (101) and a bridge portion (115). The lower part of a hoisting chain can be secured to the hook by coupling the end link (51) of the hoisting chain to the anchoring member (101) and inserting a supporting link (52) into the slot adjacent to the bridge portion (115) and to form a loose, non-loaded loop of the hoisting chain between an adjoining engagement link (53) and the anchored end link (51).

Abstract: A swivel coupling device for coupling a load to a base member. The device includes an anchor unit securely connected to the base member, a rotary member, which is rotatably journaled in the anchor unit and is provided with oppositely located recesses having pivot bearing surface portions, and a pivotable coupling member, which is provided with inwardly bent leg end portions. The leg end portions have retaining projections and are pivotably journaled in the pivot bearing surface portions. In addition, the anchor unit is shaped so as to securely hold the end portions of the coupling member within the oppositely located recesses. The coupling member is detachable from the rotary member when the anchor unit is disconnected from the base member.
