Definitions

  • a dumping device which can be used with a fork-lift truck.
  • This device comprises a frame comprising two parallel arms connected by cross bars and into which the two arms of the fork of the truck may be inserted, and a tipping bucket supported by the frame and pivotable about a horizontal and transverse axis at the front of the frame.
  • Fork-lift trucks which are provided with a bucket pivotal about a central horizontal axis to discharge its contents.
  • Such buckets require a special device mounted on the vertical masts ofthc truck.
  • the bucket is permanently connected to the truck. the latter is always used for the same type of operation.
  • the discharge operation cannot be effected much in advance of the truck.
  • a device for use with a fork-lift truck comprising a frame. comprising two parallel arms connected by cross-bars and into which the arms of the fork lift truck can be inserted. and a tipping bucket pivotally sup ported by the frame for movement about a horizontal and transverse axis at the front of the frame.
  • the device when resting on the ground may be easily picked up since it is a question ofinserting the two arms of the fork into the two hollow side members of the frame; after which the whole frame and tipping bucket are lifted. then the lifting masts are pivoted rearwardly so as to allow the bucket to be tipped rcarwardly.
  • Discharging of the bucket is effected very simply by pivotting the lifting masts forwardly and at a predeten mined point. due to the shape ofthe tipping bucket. the latter then pivots about its axis to effect discharge by tipping over.
  • the bucket according to the invention can be rapidly discharged. Moreover the fork lift truck does not require to be specially adapted to be used with the bucket.
  • FIG. 1 is an elevation of a device in the operating position on a fork lift truck.
  • FIG. 2 is a plan view of the frame of the device of FIG. I.
  • FlGS. 3 to S are diagrammatic elevation views illus trating the various stages of the discharge of the con tents of the tipping bucket.
  • FIGS. 6 to 8 are diagrammatic elevation views illus trating the operation for returning the tipping bucket to its operating position.
  • the receptacle according to the invention which is shown in FIG. 1 comprises two main parts. namely a tipping bucket or container 1 and a frame 2 supporting this bucket
  • the device is adapted to be handled by a fork lift truck having a tiltable fork lift assembly. whereof only the masts 3 and the fork or projecting member 4 are shown in FIG. I.
  • the frame 2 of the container comprises two parallel hollow side members 5 and 6 of rectangular cross section are connected by two cross bars 7 and 8.
  • the rear ends of the side-members 5 and 6 are open so as to allow the two arms of the fork 4 of the truck to be inserted into same.
  • the side members 5 and 6 respectively support tubular bearings 9 and II in which is engaged a transverse and horizontal pivot pin 12 of the tipping bucket i. This pin. also passes through an intermediate tubular bearing [3 secured to the front cross bar 8 of the truck.
  • the tipping bucket 1 has a general parallelepipedal shape. but. however. it has at the from an inclined face 1- connecting its front vertical face 15 to its lower horizontal face or base portion [6 which usually rests on the frame [2.
  • the rigidity of the bucket is ensured by angle-irons extending along the edges of the latter.
  • An angle-iron 17, is welded. by way of reinforcement. to the junction of the front vertical wall 15 and the inclined wall 14.
  • a chain 18 is hooked permanently to an eyelet l9 integral with the side member 6 of the frame 2. and to a book 21 secured to the upper part of the rear wall 22 of the tipping bucket I. or to a hook 24 integral with the fork 4.
  • the tipping bucket l is usually loaded when the latter is on the ground so that the truck may be used for other operations. Once the bucket is charged the truck with its fork 4 in bottom position approaches and the two arms are inserted into the two sections 5 and 6 of the frame 2. Then the lifting masts 3 are caused to pivot backwards and the fork 4 and the tipping bucket l which it supports are raised to a height suitable for transportation as shown in FIG. 3.
  • the chain 18 is en gaged with the book 24. and the lifting masts 3 are caused to pivot forwards so that the fork 4 and the tipping buckct I are inclined forwards.
  • the load contained in the tipping bucket l. which exerts its weight on the front and lower inclined wall 14 of the bucket. causes the latter to tilt around the pin 12 and the frame 2 to slide towards the front of the arms of the fork 4.
  • the center of gravity G of the tipping bucket is located very slightly behind the pivot pin 12. which assists tilting of the bucket and sliding of the frame 2. the sliding of the latter determining the distance of said tilting movement. Therefore. the bucket pivots in clockwise direction about the pin 12. as is diagrammatically shown in FIG. 4.
  • the chain 18 is a safety chain which has been provided to ensure that the bucket l is kept on the frame 2 during transportation. Naturally. this chain must be unhooked prior to the discharge operation and reconnected to the hook 24, in the operating position, in order to prevent the frame 2 from sliding off the fork 4 during the tilting operation.
  • a fork lift truck having a tiltable lift assembly including projecting lift members disposed for forward and backward and for upward and downward movements and for tilting movements in vertical planes; a dumping device comprising a container receptive of material for discharge therefrom and having a planar base. an opening opposite said base and a wall between said base and said opening said base having an edge portion; linkage means which comprise supporting means having a first end receptive of the projecting members of the fork lift assembly on insertion of said members at said first end of said supporting means. said LII supporting means having another end.
  • said means defining additional pivot axes includes an angle iron secured to each cornered portion to reinforce same.
  • a combination according to claim I further comprising connecting means for releasably connecting said linkage means to the fork lift assembly to prevent said linkage means from disconnecting from the fork lift assembly during the pivoting of said container.
  • connecting means comprises chain means having one end attached to said container and another end releasably attachable to the fork lift assembly.
