  • the present invention relates to a self-propelled carriage with arms Telescopic and raisable, usable for operations or work of handling, lifting, earth moving, etc., especially on building or civil engineering sites.
  • the raising or raising extension of this machine is articulable by one end at the front of the turret, around an axis horizontally, at an angle between 0 ° and 100 ° approximately, from its position folded horizontally.
  • the other end of the riser is articulable, around a horizontal axis, at the foot of the telescopic arm.
  • a lifting hook, motorized by a winch, is provided at the front end of the telescopic arm.
  • the actuators, intended for the deployment of this structure are simple cylinders without linkage, comprising a jack mounted between the turret and the riser, and another cylinder mounted between the raises and the foot of the telescopic arm.
  • French Patent No. 2,444,639 describes another example of a self-propelled machine with telescopic arm with scabbard articulation, which in a general way retains the same disadvantages: limitation of the angles of articulation of the sheath and the arm, at values of about 90 °, so the working range (limited to one 90 ° sector); limitation of use in handling loads hanging on a hook; insufficient visibility for the operator.
  • the present invention aims at avoiding all the disadvantages previously exposed, providing a gear of the kind considered, but sophisticated structure and kinematics, so in particular to optimize the volume of work, while allowing very diverse uses, visibility being also greatly improved for the operator.
  • Articulation angles of the order of 180 ° can be actually obtained by providing, according to a preferred embodiment of the invention, that the motorized control means of the articulation of the raising, relative to the frame, on an angle of the order of 180 ° are constituted by at least one jack and linkage device, and that the motorized means for controlling the articulation of the telescopic arm, relative to the extension, on an angle of the order of 180 ° are, them also constituted by at least one device with jack and linkage.
  • variable inclination of the extension relative to to the chassis combined with the varying inclination of the arm relative to the raising and telescoping the arm, allow to cover the total area of each of the four previously defined sectors, so to serve all point of the previously defined work area.
  • the structure and the kinematics of the machine make it possible cover the total volume generated by the rotation of the work area previously defined, around a vertical axis.
  • the mechanical support of the riser, in its position folded backwards allows the work of the telescopic arm alone, to characteristics identical to those of a conventional self-propelled telescopic arm, without extension.
  • the folded position of the enhances is not just a transport position, but also a real working position.
  • the support of the riser on the chassis can be a simple support guided, usually sufficient; in one embodiment, the means of support comprise, on the chassis, vertical elements in the form of "U” with lateral guides, which cooperate with a horizontal crossbar attached to the back side of the riser, in the area of the second end of this extension, on which is articulated the telescopic arm. Alternatively, it may also be a stuck support, preventing the raising of the extension, for example by means of hooks folded down and locked on said crossbeam.
  • the position of the self-propelled carriage is shaped in the driver's cab, mounted vertically on the chassis via a structure deformable parallelogram, motorized by at least one jack, to move the car between a low position and a position high.
  • the upper position of the cabin is located substantially at the end of the enhancement to which is articulable the telescopic arm, when the raiser occupies its position substantially vertical.
  • the operator of the machine can benefit, at any moment, an optimal field of view on the load to be handled, or on work equipment.
  • the motorized control of position in height of the cabin is coupled with the raises the lift, to continuously adjust and automatically the field of view of the operator.
  • the connecting device provided at the front end or "head" of the telescopic arm, can receive various work equipment, such as in particular fixed hook or lifting winch, fork, bucket, nacelle, etc., which may be brought anywhere in the previously defined work.
  • the self propelled trolley the invention is suitable for multiple and diverse uses, carried out in a large work area, including the upper rear areas and lower, which are relevant for particular applications.
  • we benefit from a significant increase in the reach of the machine thanks to the high clearance of the extension and possibilities of use with alignment of the extension and the arm telescopic, this does not exclude the possibility of working with the arm telescopic alone, the riser remaining folded.
  • the vertical mobility of the cabin provides, in all types of uses and all positions of the enhances, excellent visibility.
  • the functions of folding and Telescoping allows to place the machine in a configuration of space-saving transport, the cab is then lowered, for the road travel of the self-propelled wagon.
  • the self-propelled carriage represented in particular in FIGS. 2, has a base frame 1 mounted on tire wheels 2, and provided with stabilizers 3.
  • a rotating frame 4 On the base frame 1 is mounted a rotating frame 4, orientable about a vertical axis 5 which, in the example shown, goes through the center of the base chassis 1.
  • the chassis rotating 4 carries an articulated structure composed of a riser 6 and of a telescopic arm 7.
  • a driving cabin 8 On the rotating chassis 4 is also mounted a driving cabin 8.
  • the riser 6, consisting of a box beam, has a first end which is articulable, around a horizontal axis 9, to the front of the rotating frame 4.
  • the riser 6 is also connected to the frame rotating 4 by a motorized assembly, consisting of a cylinder 10 and a linkage 11.
  • the articulation about the axis 9, and the motorized assembly 10-11 allow a rotation of the riser 6 on an angle of the order of 180 °, between two extreme positions, one substantially horizontal in which the raises 6 is folded backwards, and the other also substantially horizontal, but in which the riser 6 is deployed forward.
  • the telescopic arm 7 is composed of several elements successive, for example a first element 12 said foot, an element intermediate 13 and a terminal element 14, which is provided, at its front end, a head 15.
  • the foot 12 of the telescopic arm 7 is articulable, about a horizontal axis 16, at the second end of the raises 6.
  • This foot 12 is also connected to the riser 6 by a set motorized, consisting of a cylinder 17 and a linkage 18.
  • the articulation around the axis 16, and the motorized assembly 17-18, allow a rotation of the telescopic arm 7, relative to the extension 6, on an angle of the order of 180 °, between two extreme positions; in one of his extreme positions, the telescopic arm 7 is folded against the riser 6, while in its other extreme position, the telescopic arm 7 is deployed in the alignment of the riser 6.
  • the rotating frame 4 comprises, at the rear, a structure support 19 for the riser 6, which structure is clearly visible in FIG.
  • the support structure 19 comprises vertical elements 20 in the form of "U”, which cooperate with a horizontal cross member 21 fixed on the face rear 22 of the riser 6, near the second end of this raises 6, therefore the hinge axis 16 of the telescopic arm 7.
  • the driving cabin 8 is mounted mobile in height on the rotating frame 4, via a parallelogram structure deformable which includes connecting rods 23 articulated on the elements 20 of the support structure 19.
  • This structure in deformable parallelogram is motorized by a jack, not shown.
  • the cabin 8 can thus be moved between a low position (FIGS. 1 and 4) and a high position ( Figure 5), with the possibility of occupying positions intermediates ( Figures 6 and 7).
  • the vertical displacement plan of the cabin 8 is located on the side of the plane of displacement of the riser 6 and telescopic arm 7.
  • the head 15 of the telescopic arm 7 is provided with a link 24, for receiving various work equipment interchangeable, thus attached to the front end of the arm 7.
  • the equipment of work can be in particular a bucket 25 (FIGS. 2 and 6), a hook fixed or lifting winch 26 (Figure 3), a fork 27 ( Figures 4, 5 and 6) or a personnel lift nacelle 28 (FIG. 7).
  • the riser 6 In the folded transport position, as shown in FIG. the riser 6 is lowered substantially horizontally, and it rests on the support structure 19.
  • the telescopic arm 7 is retracted, and folded over 6.
  • Cab 8 is lowered, and it is at the front of the rotating frame 4, on the side of the riser 6 and the arm 7.
  • the head 15 of the arm 7 and the bucket 25 take place in front of the base frame 1.
  • Figure 4 illustrates, more precisely, the use of the trolley self-propelled with its raising 6 folded backwards, and resting on the support structure 19 present at the rear of the rotating frame 4.
  • the arm 7 here can rotate, around the horizontal axis 16 held fixed, between a substantially horizontal position and a substantially vertical position, this arm 7 can, moreover, be telescoped.
  • the self-propelled carriage is thus can be used as a machine with a single telescopic arm, for example for the handling a load 29 placed on a fork 27.
  • the self propelled trolley can also be used, as shown in FIG. 5, with its riser 6 deployed vertically, the telescopic arm 7 can have a variable inclination, and be more or less telescope.
  • the machine can thus ensure the distribution of a load 29 above a low building 30, or beyond an obstacle such as wall.
  • the cabin 8 is advantageously brought into high position, substantially at the upper end of the raises 6, the axis of vision 31 of the operator then passing over the building 30 or other obstacle so as to maintain the direct vision of the load 29 during handling thereof.
  • the self propelled trolley is still usable with its riser 6 deployed horizontally to the front, and extended by the telescopic arm 7, aligned horizontally with this enhancement 6.
  • This use position allows the distribution a load 29 through an opening 32 of a building 30.
  • Figure 6 illustrates other possibilities of use, allowing to perform work below the support plane 33 of the truck propelled.
  • the extension 6 deployed forward, and with the telescopic arm 7 directed downward (in phantom lines), it is possible to distribute a load 29 at the bottom of an excavation 34.
  • the riser 6 held in an inclined position, and with the telescopic arm 7 folded on this enhancement 6 (drawn in continuous lines), it is possible to move the bucket 25 on an inclined plane 35, for work of earthworks: construction of an inclined structure (road embankment, bank of canal, dike), excavation.
  • the equipment of work carried by the telescopic arm 7 it is also possible to perform the handling of rubble, pallets of materials, concrete, etc ... along inclined plane 35.
  • Figure 7 illustrates the possibilities of using the truck self-propelled, equipped with a nacelle 28 maintained horizontal, on which can take place one or more people.
  • the nacelle 28 allows work at heights, in the upper rear areas I and II (such as than previously defined), for example for the laying of frames or the dressing of buildings, even in narrow bays that do not allow the complete rotation of the rotating frame 4 about the vertical axis 5.
