Definitions

  • the invention relates to a compact multiuse mobile work tool.
  • the prior art teaches compact multiuse mobile work tools exhibiting masses such as to enable them to be used inside buildings for all principal operations for which vehicles designed for use on building sites are designated.
  • mini-loader blades mini-excavators and mini-elevators, but as yet no compact work tools considered to be multi-use in the sense that they are able, when apposite work tools are applied, to perform the tasks usually associated with building sites.
  • 1 denotes a frame provided with two pairs of wheels 2.
  • a pair of tracks might be fitted instead of the wheels.
  • a rotatable platform 3 is pivoted about a vertical axis perpendicular to a plane identified by the axes of the wheels 2.
  • a motor 4 located posteriorly thereon; a driver's cockpit 5 for the operator, and a manoeuvring arm 6, situated in a decentralized position by the side of the cockpit 5.
  • the manoeuvring arm 6 is constituted by two principal segments 7 and 8, which are hinged one to the other at respective ends thereof.
  • the first segment 7 exhibits a first end hinged by a pivot 17 at a front end of the rotatable platform 3.
  • the second segment 8 is instead provided, at a free end thereof, with a rapid universal attachment 9 for tools or equipment, said rapid universal attachment 9 being is equipped with hydraulically-activated organs 10 for manoeuvring tools and equipment in the articulation plane of the arm 6.
  • the first segment 7 is brought to rotate in two directions about the pivot 17 by a mechanical lever system comprising: a lever 11 hinged at a first end thereof to the rotatable platform 3 by means of a pivot 15; a connecting member 12, hinged to a second end of the lever 11 and to the first segment 7, at a point situated at a predetermined distance from the axis of the pivot 17; a hydraulic cylinder 13 exhibiting a bottom end which is hinged to the rotatable platform 3 and a stem end hinged, by means of a pivot 14, to an intermediate point of the lever 11.
  • the lever system constituted by the lever 11 and the connecting member 12, constitutes together with the first segment 7 and the rotatable platform 3 a four-bar hinge wherein the fixed member is constituted by the rotatable platform 3 itself.
  • the entire lever system is proportioned such that the lever 11 exhibits a shorter length than the connecting member 12, which connecting member 12 pivot axis to the first segment 7, in the position represented in figure 1, is located at a predetermined distance from the axis of the pivot 17.
  • Said pivot 17 is located in an advanced position and situated inferiorly to (and is parallel to) the axis of the pivot 14 by means of which the lever is hinged to the rotatable platform 3.
  • a complete series of tools and equipment can be coupled to the rapid universal attachment 9.
  • a loading scuttle 20 can be applied to the rapid universal attachment 9.
  • the machine, fitted with the loading scuttle 20, can function as a self-propelled loader of the type known as skid steer loader.
  • the loading scuttle 20 manoeuvrability is achieved through the arm 6. Horizontal movements are obtained by movements of the entire vehicle on the wheels 2 (or tracks), combined with rotation movements of the rotatable platform 3.
  • the machine becomes a mini-excavator; also in this case the manoeuvring of the bucket 21 is realized by means of the manoeuvring arm 6.
  • the ability of the rotatable platform 3 to rotate about a vertical axis with respect to the frame 1 allows operation in every direction, at 360 degrees, without having recourse to movements of the chuck 2. Thanks to its conformation and to the conformation of the mechanism producing the rotation of the first segment first segment 7, the manoeuvring arm 6 has a high manoeuvrability in a vertical plane.
  • the rotation of the whole rotatable platform 3 about a vertical axis means that the arm 6 can operate in any direction.
