  • This invention relates to a public works machine con- 'ance stituted by a chassis, a jib articulated on said chassis, and a beam articulated on said jib about an axis, [52] U.S. Cl. 173/46, l73/2g,5l7??/ ;31, which is disposed n the median Zone of Said beam, whilst a first working tool is coupled with a first end of [51] Int. Cl. E21c 11/02 said beam, wherein a second working tool is coupled [58] Field of Search 173/28, 29, 43, 46;

  • SHEET 30F 3 J1 QQWIWIIIIJ% 1 PUBLIC WORKS MACHINES The present invention relates to public works machines, and more particularly one provided with a beam supporting two working tools.
  • the present machines are very special machines designed for a very precise purpose.
  • the invention intends to remedy these disadvantages and to this end proposes a new beam for a machine, known per se, which does not present, a priori, any notable particularity, thus for wide distribution.
  • this new beam By adopting this new beam to replace the beam which normally equips the public works machines, without any special adaptation being necessary, the invention enables a machine to be made very simply, which isperfectly adapted to the execution of the two distinct phases of operations. 1
  • the invention therefore has for its object a public works machine constituted by a chassis, a jib pivoted on said chassis and a beam pivoted on said jib about an axis, disposed in the median zone of said beam, whilst a first working tool is coupled to a first end of said beam.
  • a second working tool is coupled to the second end of the beam, whilst each of the first and second working tools is able to be placed in working position and being held coupled at its corresponding end to the beam.
  • the beam, to which the first and second working tools are coupled, is advantageously slightly concave.
  • the first working tool is constituted by adigging tool, whilst the second working tool is constituted by a pulley system;
  • this first working tool which is then a digging tool
  • the machine comprises in addition adevice'for removably holding the free end of said elongated tool out of range v of the ground located beneath the jib, perpendicularly to and on either side of said jib.
  • This device is generally constituted by a link means, such as a cord, which connects the elongated tool to the jib of the machine.
  • a link means such as a cord
  • the above-mentioned device is constituted by a supple link means, such as a cord, one end of which is attached to the jib, the other end to the body of the auger, and which may be wound on said auger.
  • FIGS. 1, 2 and 3 show the same machine according to the invention in the course of three successive phases of its functioning.
  • the machine comprises in fact the elements constituting a hydraulic shovel, known per se, except for the beam and the tools coupled with the beam.
  • a chassis constituted in the present case by the base 1, on which the turret 2 is mounted to pivot, and which is provided with rolling members 3 by means of which the machine rests on the ground 4.
  • a jib 5a is pivoted about an axis 6 on the turret 2, whilst a hydraulic jack 7a is coupled between said jib 5a and said turret 2.
  • the chassis could possibly not comprise a turret ⁇ but form a one-piece assembly grouping the base 1 and the turret 2.
  • a beam 8a is articulated about an axis 9a on the, jib 5a, its hydraulic control jack 10a being coupled between said beam 8a and said jib 5a.
  • the jib and the beam have been shown in the following two positions: .in solid lines, these elements are referenced, in
  • the beam 8a is elongated in form.
  • the ends 11a and 12a and the median zone 13a may be distinguished.
  • a pulley 14a is mounted to rotate, whilst a lifting cable 15a, wound on the drum of a winc'h 16 disposed on the turret 2, supports apulley-block 171110 which a hook 18a is coupled.
  • an auger 19a driven by a hydraulic motor 20a.
  • This auger 19a is coupled with the beam 8a by a universal joint 21a, or by a similar device, preferably, but not obligatorily, disposed laterally on the beam 8a, in order to permit an easier clearance of the auger 19a parallel to the jib 5a and to the side thereof.
  • the auger 19a has already dug a hole 22.
  • the axis of articulation 9a of the beam 8a on the jib 5a is disposed in the median zone 13a. Furthermore, when the hole 22 is first dug, the beam and jib are in their positions 8b and 5b respectively.
  • FIG. 2 the working equipment of the machine is shown in a third position.
  • a pole 230 is being taken from areserve of .poles 24.
  • the jib is at 5c, the base at 8c, the lifting cable atlSc, the pulley-block that it supports at 17c and the lifting'hook at 180.
  • the pole 23c in the course of being lifted, is coupled to hook by link means, such as cords 250.
  • the beam is tucked in under .the jib 5c and its end 12c, to which. the auger is coupled, is disposed therebeneath.
  • the auger is disposed at 19c, substantially parallel to the jib c, and is locked in this position by a clamp means 27a, 27c and 27d, respectively in FIGS. 1, 2 and 3; a supple connection means such as a cord 26 attached by one of its ends to a ring 280, 28c or 28d according to the Figures considered, integral with the jib, being wound by its second end to the auger 19c itself.
  • the pole is shown now at 23d immediately above the hole 22.
  • the working equipment is in a fourth position, the jib being at 5d, the beam at 811, the lifting cable at d, the pulley-block that it supports at 17d and the lifting hook at 18d.
  • the cords which connect the pole 23d to the hook 18d are referenced at 25d.
  • the auger now hangs vertically at 19d, like the pole 23d.
  • the beam is slightly concave, in the present case in .its median zone 13d, the pole 23d being disposed as near as possible to the beam, in order to permit the auger 19d to be disposed to the side of the pole 23d without interfering therewith, the ends 11d and 12d of the beam 8d themselves then being disposed in distinct vertical planes.
  • the machine is disposed as shown in FIG. 2, in which the crane equipment permits the prehension and handling of the pole 230. It will be noted on this subject that the mode of fixing the auger on the end 12c of the beam has enabled said auger to be brought into position 19c, in which it is held by the cord 26 attached to the ring 280, and locked in the clamp 270.
  • This feature is important, as it is associated with the possibility of lowering the jib and of disposing it, as well as the beam, substantially horizontally, and thus of obtaining a satisfactory and sufficient range of the hook 18 c, without it being necessary to resort to assembling said hook to the end either of a small foldable jib or of a telescopic jib, as is the case in prior known machines.
  • Public works machine comprising, a chassis, a jib articulated on said chassis, a beam articulated on said jib about an axis disposed in the median zone of said beam, a first working tool coupled to a first end of said beam, and a second working tool coupled to the second end of said beam, the second working tool being constituted by a pulley block for material handling purposes.
  • said first working tool is constituted by a tool of elongated form, supple link means suspending said first working tool from said beam and means for removably holding the free end of said elongated tool out of range of the ground beneath said jib, perpendicular to and on either side of said jib.
