Definitions

  • ABSTRACT relates to a public works machine comprising a platform equipped with a drivers cabin which is fast therewith and is oriented in the direction of translation of the machine, and with an operating equipment comprising a jib articulated on the platform about an axis 9 disposed substantially to the side of the drivers cabin, while this jib is contituted by two elements articulated with respect to one another about an axis which is substantially perpendicular to the axis of oscillation of the jib on the platform, wherein the axis of articulation of the two elements of the jib may be in a substantially vertical position, in which it is disposed substantially plumb with the front face of the drivers cabin, while the relative rotation of the two articulated elements of the
  • the operating equipment is continually disposed to the front of the drivers cabin; in the best of cases, this equipment is arranged to the front and to the side, as in the machines with an offset working.
  • the invention intends to remedy this state of affairs and to this end proposes a novel arrangement such that, when the operating equipment has a certain configuration, it is no longer disposed to the front of the drivers cabin but almost completelyto the rear thereof, and therefore allows complete visibility of the ground in front of the drivers cabin, from said cabin.
  • the invention therefore has for its object an improved arrangement for a public works machine comprising a platform equipped with a drivers cabin is fast therewith and is oriented in the direction of translation of the machine, and with an operating equipment comprising a jib articulated to the platform about an axis disposed substantially to the side of the driver's cabin.
  • This jib is contituted by two elements articulated with respect to one another an axis which is substantially perpendicular to the axis of oscillation of the jib on the platform.
  • the axis of articulation of the two elements of the jib When the axis of articulation of the two elements of the jib is vertical, it is disposed substantially plumb with the front face of the drivers cabin, while the relative rotation of the two articulated elements of the jib may be greater than 90 and preferably substantially equal to 180 and that rotation preventing means may integrate the two elements of the jib.
  • Second locking means are advantageously provided which are capable of integrating the element of the jib equipped with the operating tool and the zone of the platform located to the rear of the drivers cabin.
  • FIG. 1 is an elevational view of a machine with an arrangement according to the invention
  • FIG. 2 is a view as seen in the direction of arrow F of FIG. 1;
  • FIG. 3 is a plane view of the machine shown in FIG. 1.
  • the machine with the arrangement according to the invention is constituted, in the embodiment chosen, by a chassis 1 provided with rolling members, here with wheels 2.
  • a chassis 1 provided with rolling members, here with wheels 2.
  • a platform 3 On the chassis l is rotatably mounted a platform 3 on which is disposed an operating equipment constituted by a jib articulated on the platform 3 about a horizontal axis 9 and by a balance beam 7 articulated to the jib and provided, at its free end, with a bucket 8.
  • the jib is itself constituted by the elements 4 and 6. These elements are articulated with respect to one another about an axis perpendicular to the axis 9.
  • the element 6 is articulated to the platform 3 about the axis 9, whilst the balance beam 7 is articulated to the element 4 about an axis 11.
  • a drivers cabin 5 is fixedly mounted on the platform 3 and is oriented in the direction of movement of the machine, when the platform 3 is itself oriented so that, from the drivers cabin, one looks towards the front of the machine, as shown in FIG. 1.
  • FIG. 1 shows that one of the notable points of the arrangement chosen is that, although the axis 9 is disposed to the side of the drivers cabin 5 and substantially at the same level thereas, neither to the front nor to the rear of the driver's cabin 5 and also close to the floor of said cabin 5, the axis 10, when it is vertical, is advantageously disposed higher than the upper part of the drivers cabin and substantially does not exceed the front face 5a of said cabin. Consequently, the part of the operating equipment connected with the element 4 of the jib is disposed completely to the rear of the front face 50 of the drivers cabin 5 when the element 4 has turned with respect to the element 6, as shown in dashed and dotted lines in the Figures.
  • the relative rotation of the elements 4 and 6 is moreover substantially equal to so that, in position 4, the element on which the beam is fixed has disposed the beam and the bucket at 7' and 8 to the rear of the drivers cabin 5.
  • Rotation locking means are provided for integrating the elements 4 and 6 of the jib in operating position.
  • a pin 12 cooperates with apertures 13 and 14 made respectively in the elements 4 and 6, aperture 13 being more clearly visible at 13 in position 4 of the element 4.
  • the pin 12 is of course able to be fast with the rod of a small control jack in order to have its engagement and disengagement in and from the apertures 13 and 14 remotely controlled from the drivers cabin for example.
  • the elements 4 and 6 are generally in the same plane. However, they may also be contained in different planes forming a small angle therebetween.
  • the operating equipment connected with the jib element, on which the beam is articulated when disposed at 4'-7-8, it may be fixed to the zone 3a of the platform 3 located to the rear of the drivers cabin 5, by integration means.
  • These means are for example constituted by a fastening member 15 welded to the platform 3 in the zone 3a with which a connecting means such as'a rod 16 articulated to the bucket cooperates, the fastening member 15 and the rod 16 being temporarily connected by a removable pin 7.
  • the two elements once integrated, may be contained in separate planes, so that the machine may be used for offset working.
  • the angle of the planes of the elements 4 and 6 and therefore the amount of ofiset of the tool may be adjusted.
  • Such a system may finally replace the locking means 15-16-17, since in fact it enables the element 4' to be held in a position facing the rear.
  • a public works machine comprising, a platform having a driver's cabin fixed thereon and oriented in the direction of translation of the machine, operating equipment including a jib having an inner part oriented in a first vertical plane and pivotally attached to the platform at one side and rearwardly of the driver's cabin for pivotal movement in said vertical plane and an outer part supporting an earthworking tool on its outer end and pivotally connected to the outer end of the jib inner part for horizontal swinging movement through an arc substantially greater than 90 relative to the inner part of the jib, between a first operative position extending outwardly from said inner part of the jib substantially in said first vertical plane and a second inoperative position extending rearwardly of the pivotal connection of the inner and outer jib parts in a second vertical plane substantially parallel to said first vertical plane, said pivotal connection between said jib parts lying in a plane which is immediately adjacent the front of the drivers cabin whereby movement of said outer part to said second position enables an unobstructed forward view from the
  • a public works machine as claimed in claim 1 wherein, the arc of horizontal rotation of the outer jib part relative to the inner jib part is at least 4.
  • a public works machine as claimed in claim 1 wherein, there are second locking means located on the platform well back of the driver's cabin for securing the outer jib part to the platform when the outer jib part is in its second position.
