  • Patent number: 8157304
    Abstract: There is disclosed a lifting sling system for connecting various loads to a lifting hook (1), comprising a small number of combinable lifting sling units (10, 20), each consisting of a number of pre-assembled parts (11, 12, 13; 21, 22, 23). These units include at least one dual lifting sling unit (20) and possibly no more than two single lifting sling units (10). The units can be combined in a small number of predetermined combinations in accordance with information provided on an information carrier (32) which is permanently attached to the lifting sling system.

  • Patent number: 7269937
    Abstract: A chain shortening device is described. The device has the general shape of the letter “C”. A single slot (20) extends longitudinally along the elongated body (10) of the device. The single slot has a central widened portion defining a lead-through opening (20E) through which a loop of an associated chain can be inserted, whereby the device can be handled as a separate unit and be attached sideways to an associated chain.

  • Patent number: 6648388
    Abstract: A method of providing a safety measure when lifting a load (13) by 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).

  • Patent number: 5906032
    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).

  • Patent number: 5884950
    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).

  • Patent number: 5851040
    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.

  • Patent number: 5829810
    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.
