Definitions

  • lift trucks which actually resemble small crane trucks, generally suffer from a series of design problems deriving from the need to provide the operator with perfect visibility when the lifting arm is lowered into its rest position, while at the same time ensuring that the frame to which said arm is hinged is sufficiently rigid.
  • the known designs comprise a robust welded metal plate frame which is stiffened transversely by several section bars or tubes, to form a perfect base for the articulation of the lifting arm.
  • the drive cab is generally located to the side of this frame, in a position between the device wheels, so that in practice it juts out.
  • a further drawback derives from the fact that the jutting location of the engine, which is always heavy, detracts from the overall stability of the system and makes torsional stiffening of the frame necessary, this not always being easy to achieve.
  • the present invention provides a self-propelled lift truck of the aforedescribed type which obviates the aforesaid drawbacks by virtue of a particular frame configuration which enables the engine to be located within or substantially within the frame in a position to the rear of that occupied by the drive cab.
  • Figure 1 shows a frame 1 mounted on wheels 2 and supporting in a rear position a transverse shaft 3 on which a telescopic arm 4 is pivoted.
  • the telescopic arm 4 is driven in a vertical plane by the cylinder-piston unit 20 which at one end is hinged to the frame 1 and at its other end is hinged to the telescopic arm 4 at the bracket 21.
  • a drive cab 5 provided with front lamps 6 and an upper accident prevention guard 7.
  • Figure 2 shows that the frame 1 is composed of two robust longitudinal plate metal members 8, which extend at their rear in the form of two plates 81 acting as supports for the transverse shaft 3.
  • the longitudinal members 8 and the plates 81 are made consistent by a series of transverse beams, of which Figure 3 shows the front beam 9 and, for the purposes of understanding the invention, an intermediate beam 99.
  • brackets 10 Only one of the brackets 10 is shown for clarity.
  • Two jutting beams 12 are welded to an intermediate position on and perpendicular to the frame 1, and upperly carry the means 13 for fixing the cab 5.
  • the rear part of the frame 1 comprises a central wall 14 which is provided with large apertures, not shown in the figure, for receiving the lateral parts of the engine, and is maintained in position by strong welded tubes 15a, 15b, 16a and 16b, which join said central plate to the two side plates 81.
  • One of the two compartments into which the rear part of the frame 1 is divided by the central wall 14 comprises a thick tube 17 welded between said central wall 14 and one of the plates 81, and to which there are welded two robust brackets 18 provided at their end with bushes 19.
  • the bushes 19 form the seat for the transverse hinge pin for the said cylinder-piston unit 20 which vertically drives the telescopic arm 4.
  • a compartment 22 is formed containing the engine 23 and the relative hydraulic pump 26, these operating all the machine members.
  • the engine 23 is fixed to the frame 1 by four support brackets 24, which are fixed to the resting surface of the engine 23 via rubber blocks 25.
  • the hydraulic pump 26 is juttingly fixed to the front of the engine casing, and is supported by it.

Claims (1)

  1. Ein Hubwagen mit Teleskop-Arm, bestehend aus einem auf Räder montierten Hauptgerüst, auf dem sowohl eine Kabine für den Fahrer als ein senkrecht schwenkbarer Teleskop-Arm angebracht ist. Dieser Teleskop-Arm ist hinten an dem Gerüst befestigt. Der Hubwagen zeichnet sich dadurch aus, daß das Maschinengerüst einen hinteren Bereich mit zwei parallelen, nach oben überstehenden Platten (8) aufweist. Diese beiden Platten bilden einen durch eine mittlere Trennwand (14) getrennten Raum. Diese Wand ist ist mittels Rohren (15a, 15b, 16a, 16b) an den Platten festgeschweißt und bildet zwei unabhängige Fächer, von denen eines in seinem hinteren oberen Bereich zwei Buchsen enthält, die die horizontal ausrichtbare Welle des Schwenkarmes des Kranes stützen. Die Buchsen werden jeweils von einer der Platten (81) des Gerüsts und von der o.g. mittleren Trennwand (14) sowie durch einen Querträger (17) gestützt, der zwei Vorsprünge (18) aufweist, an deren Spitze die beiden Buchsen (19) angebracht sind, die den Scharnierzapfen für die den Auf- und Abstieg des Teleskop-Armes ausführende Zylinder-Kolben-Gruppe (20) enthalten. Das zweite Fach (22) enthält Halterungsvorrichtungen (24) für den Verbrennungsmotor (23), der die Gruppe zusammen mit der entsprechenden Hydraulikpumpe (26) antreibt.
