Definitions

  • the invention relates to industrial trucks.
  • Electric carts are reserved for industrial use because of their flexibility and simplicity of driving, their absence of noise and pollution, their reduced dimensions which allows them to move easily in a congested environment, while thermal carts are generally intended for outdoor use, are able to cross slopes and lift larger loads.
  • Thermal carriages use for lifting loads either a front mast system or a telescopic arm system allowing a longitudinal offset of the load, while so far, an electric trolley with telescopic arm has not been produced.
  • Known carriages of this type are all equipped with a mast.
  • the small width of the electric forklifts, the central location of the driving position and the size of the batteries prevent the adoption of a lifting means for these trucks other than a mast and in particular a telescopic arm.
  • the object of the present invention is to provide an industrial handling trolley with an electrical energy source, the lifting equipment of which is constituted by a telescopic arm, which remains very compact in order to be able to move easily in a room. congested, has an arm arrangement ensuring unobstructed visibility, has a good balance of the masses and a good weight centering which allows to obtain a large lifting capacity and longitudinal offset safely, allows easy and fast handling of accumulator tanks and retains an acceptable autonomy.
  • the trolley according to the invention comprises, in a chassis which will be described in more detail in relation to FIG. 4, a telescopic arm 1 arranged in the median longitudinal axis of the trolley (FIG. 3) on the left side of this arm 1, a driving and maneuvering station 2 provided with a seat 3 mounted on a tilting cover 4 closing a removable box 5 in which the electric accumulators 6 are housed.
  • the carriage has on its right side a second removable box 7 for another series of electric accumulators 6.
  • the chassis carries two front wheels 8, non-steerable and non-drive, and a single rear wheel 9, steerable and drive.
  • the driving position 2 is protected by an open cabin 10 extending over practically the entire length of the carriage, from a point located in front of the front wheels 8 to a point located at the rear end of the box.
  • accumulators 5 Figure 1).
  • the chassis proper is mainly constituted by a longitudinal beam and a transverse beam 12.
  • the longitudinal beam consists of two vertical plates 13, 14 fixed to each other by spacers 15.
  • the plates 13 and 14 are of such shape that they also constitute the uprights of the bracket 16 of articulations of the lifting arm 1.
  • the beam 12 is constituted as a hollow box also acting as a reservoir for the hydraulic liquid necessary for the operation of the arm.
  • the beam 12 is closed at its two ends by flanges 17, 18 which carry the front wheels 8.
  • flanges 17, 18 which carry the front wheels 8.
  • FIG. 4 shows that the bearing shafts of the front wheels 8 pass through the flanges 17, 18 and are fitted with disc brakes 19.
  • the spacers 15 are arranged towards the rear of the plates 13 and 14. This arrangement is advantageous because it allows a well to be formed between the plates in which the arm 1 can be housed in the low position in order to give visibility of the driver. However, it ensures sufficient rigidity of the beam 11 because the lifting forces will be essentially supported by the rear part of the carriage.
  • the transverse beam 12 acts as a spacer in the front part.
  • a floor 20 which has on either side of the beam 11 a large recess 21 open laterally.
  • the opposite edges of this recess 21 have holes 22, reinforced with plates 23, intended to cooperate with centering pins, not shown, provided under the boxes 5 and 7 for housing the accumulators 6.
  • Figure 4 also shows how one can very easily, using another forklift represented by its only forks 24, handle the boxes 5 and 7 by lifting them from below. This is an important advantage in view of the fact that these handling operations are very frequent taking into account the need to recharge the accumulators.
  • the front end of the beam 11 is situated slightly behind the front limiting plane of the carriage, which provides a space 25 in which at least the support 26 of the deck 27 located at the end of the arm 1 can be retracted, which increases the compactness of the carriage and its stability during its movements with a load close to ground level.
  • the floor 20 extends to serve as a support for counterweights 28.
  • the floor 20 also has an additional recess 29 for the passage of the rear wheel 9.
  • chassis indicates the carrier structure of the carriage, that is to say that on which all the equipment is mounted and which supports all the efforts.
  • the transverse part of the chassis can advantageously be replaced by a bridge which while fulfilling the function of beam will ensure the transmission of the torque and / or steering movements at the front wheels.
