Definitions

  • This accessory consists of a plate-shaped object, ribbed in accordance with the requirements of strength and elasticity, and having at its centre of gravity a suspending fitting and, distributed round the whole circumference near to the periphery, at least three members for the attaching of chains or ropes for suspending the transported goods.
  • the star-shaped plate with the supporting lengths of chain or rope can be suited to any position of the goods, and it is at once possible to lift any desired object without great previous knowledge.
  • Store rooms and warehouses are often very limited in height, and this renders transport appreciably more dicult.
  • the accessory according to the invention in which the lengths of chain or rope no longer run together in the shape of a pyramid, the fixing point can be kept lower; it is therefore possible to stack goods to a greater height.
  • Fig. 1 is a view looking down on a carrying arrangement with provision for the possible attachment of 6 chains
  • Fig. 2 is a cross-section through the same arrangement in condition ready for service
  • Figs. 3-6 show each an example of the manner of fixing the object in side view or seen from above.
  • the reference numeral 1 designates the plate-like carrying plate, which has strengthening ribs 2.
  • a bolt 3 is provided, which terminates below in a hook 4 and is connected above to a carrying ring 5.
  • a throughgoing slot 6 is provided, and at right angles to it a groove 7.
  • lamellae 8 are provided; they serve for exible equalising of the forces.
  • the grooves 7 serve for taking chain links 9a and are designed to suit them.
  • the slot is provided for the next chain link 9b.
  • the carrying plate may be made thicker, with more ribs, or larger in diameter.
  • the shape of the carrying plate may be circular, oblong or polygonal.
  • a second fixing member for smaller chains can be inserted to help if necessary.
  • the carrying ring S and also the hook 4 may be replaced by a member suitable for the particular service requirements, for instance by a lifting magnet.
  • the carrying plate may, depending on the maximum service requirements, be provided with a number of xing facilities for lengths of chain or rope, this number being greater than two. The greater the number of fixing facilities, the more universal will be the adoption, but for reasons of strength the maximum number should not exceed 16. Preferably, however, one of the numbers 3, 4, 6, 8, 12 or 16 will be chosen. In this way any desired object can be fixed in such a manner that it maintains a definite position when being lifted.
  • Fig. 5 shows an example of an object which has its centre of gravity more towards one side, but nevertheless remains in its horizontal position.
  • the carrying plate has eight fixing facilities for the lengths of chain or rope.
  • the number of fixing facilities is of no importance to the accessory.
  • the described accessory may be adopted in any industry where hoists and the like are required.
  • An accessory for hoists comprising a horizontal plate provided along its edge with a plurality of vertical, throughgoing slots extending from said edge inwardly, the upper surface of said plate being provided with a plurality of pairs of aligned recesses positioned on opposite sides of and opening into respective ones of said slots in spaced relation to said edge and to the ends of said slots, each pair of recesses being thus adapted to receive a link of a chain having its next lower link held in the corresponding slot, and suspension means ou said plate for supporting the latter from above.
  • An accessory for hoists comprising a centrally symmetrical .horizontal plate and suspension means at the center of said plate, said plate being provided at uniformly spaced portions of its periphery with radially inwardly extending vertical, throughgoing slots, the upper surface of said plate being provided with a plurality of pairs of aligned recesses positioned on opposite sides of an opening into respective ones of said slots in spaced relation to said periphery and to the ends of said slots, each pair of recesses being thus adapted to receive a link of a chain having its next lower link held in the corresponding slot.
