Definitions

  • the present invention relates to an implement for lifting oil barrels or like, substantially cy ⁇ lindrical objects, comprising at least three clamping jaws or clamping jaw-like members which are applicable to the outer side of the barrel and one of which is pivotal relative to the other two jaws in order, upon application of a tractive force in a coupling means, to bring about concurrent clamping of the jaws against the barrel, the shortest distance between the first clamping jaw and an imaginary line between the other two clamping jaws on the one hand exceeding the radius and, on the other hand, being less than the diameter of the barrel.
  • a lifting implement of the type generally described above is previously known from U.S. patent specification 3,915,488.
  • This known implement is however intended only for lifting oil barrels which are standing and is not suited for lifting barrels which are lying.
  • the three clamping jaws in the known implement are ar ⁇ ranged on three associated arms which are rigidly inter ⁇ connected at a central junction so as to form a Y-shaped yoke.
  • Two clamping jaws or more exactly legs thereof are rigidly connected to two arms of the yoke while a third, pivotal clamping jaw or more exactly one leg thereof is articulated to the free end of the third arm.
  • an operating rod which extends through the lower part of a lifting link to the upper end of which a lifting hook can be applied.
  • the lifting link is main ⁇ tained in place by means of angular guide rods which are fixed at the junction between the three arms of the yoke. From the lower part of the lifting link, the ope- rating rod projects a substantial distance and is termi ⁇ nated by a stop restricting the outward pivotal movement of the movable clamping jaw away from the centre of the lifting yoke.
  • the weight of the operating rod en- sures that the movable clamping jaw is swung out so that the three clamping jaws can concurrently engage about the edge hoops of one end wall of the oil barrel.
  • a lifting hook is thereafter applied to the lifting link with the application of a tractive force therein, the operating rod is caused to pivot from a lower to an upper position.
  • the movable clamping jaw will also be pivoted inwardly towards the barrel such that an arcuate part of the jaw is applied underneath the edge hoops at the barrel end wall.
  • the present invention has for its object to over ⁇ come the drawbacks indicated above and to provide a lifting implement which can lift oil barrels in an ex- tremely reliable manner, whether the barrels are stand ⁇ ing or lying.
  • this is achiev ⁇ ed in that the first clamping jaw is provided on an elbow or angularly projecting member rigidly connected to a first arm, while the other clamping jaws are con- nected to each other and to a common second arm pivo- tally connected to the first arm by a joint which is located both at a distance from and between the coupling means and said elbow, preferably considerably closer to the elbow than to the coupling means, the application of said tractive force in the coupling means causing it to move away from said second arm and causing the first arm to pivot outwardly away from the second arm as at the same time the clamping jaws are moved closer to each other and to a barrel located between them.
  • Fig. 1 is a perspective view of the implement according to the invention
  • Fig. 2 is a perspective view showing the same implement applied to a lying oil barrel
  • Fig. 3 is a perspective view illustrating the implement and the barrel when in an upright position.
  • 1 designates an oil barrel which in a known manner comprises a cylindrical wall 2 and two opposite end walls 3 one of which has a draining hole 4 and a venting hole (not shown). Along the peripheries of the two barrel end walls there extend reinforcing hoops 5 which project a short distance from the circum ⁇ ferential surface of the cylindrical wall 2.
  • the implement 6 according to the invention as il ⁇ lustrated in Fig. 1 comprises two mutually movable arms 7, 8 the first of which is provided with a first clamping jaw 9 while the other is associated with two other clamping jaws or clamping jaw-like members 10, 10'.
  • the two hooks 10, 10' are in the form of hooks which can be clamped under the reinforcing hoops 5. As appears from Fig. 1, the two hooks 10, 10' are provided at the opposite ends of a cross-piece 11 to the central portion of which the arm 8 is rigidly connected.
  • a coupling means in the form of a shackle 12 in which a hook or other connecting means can be fastened.
  • the arm 7 has an elbow or angu ⁇ larly projecting member 13 on which the first clamping jaw 9 is arranged.
  • the two ' arms 7, 8 are interconnect ⁇ ed by means of a joint 14 which allows pivotal move- ment of the arms with respect to each other. This joint is located in the immediate vicinity of the free end of the arm 8 remote from the cross-piece
  • Fig. 2 illustrates most clearly how the shortest distance between the clamping jaw 9 and the cross-piece 11 carrying the two hooks 10, 10', on the one hand exceeds the radius of the barrel 1 and, on the other hand, is less than the diameter of the barrel. This means that the hooks 10, 10', in the manner illustrated in Fig. 2, can be easily and conveniently applied against the barrel although it is lying.
  • the implement accord ⁇ ing to the invention can also be used for lifting a standing barrel up to a level above the surface on which it was resting, optionally while simultaneous ⁇ ly transporting the barrel from one place to another, as intimated in Fig. 3.
  • the arm 7 is pressed inwards against the action of the spring 15 until the clamping jaw 9 is in place behind the hoop 5.
  • the spring will hold the clamping jaw pressed against the barrel with a slight pressure so that the implement is maintained in the position illustrated until a lifting hook is connected in the shackle 12.
  • the provision of the spring 15 dispenses with the need to manually hold the implement in position until the hook has been applied.
  • the invention is not restricted only to the embodiment described above and illustrated in the drawing.

Abstract

Un ustensile (6) pour faciliter le levage de barils de pétrole ou autres comporte deux bras mobiles réciproquement (7, 8) dont l'un comporte une première mâchoire de serrage (9) lorsque l'autre possède deux secondes mâchoires de serrage espacées ou éléments similaires à des mâchoires de serrage (10, 10'), la plus courte distance entre la première mâchoire de serrage (9) et une ligne imaginaire entre les deux autres mâchoires de serrage (10, 10') d'une part dépassant le rayon et d'autre part étant inférieure au diamètre du baril. La première mâchoire de serrage (9) est disposée sur un élément saillant angulairement (13) connecté de manière fixe à un premier bras (7) alors que les autres mâchoires de serrage (10, 10') sont reliées l'une à l'autre et connectées à un second bras commun (8) qui est relié de manière pivotante au premier bras par une articulation (14) située à une distanc substantielle du dispositif de couplage (12) et a une faible distance de l'élément saillant (13).
