Definitions

  • Lift trucks are standardized according to DIN 15.140.3 G or 4.L. These are mainly steered on the rear side facing away from the load wheels. The vehicle body is made in one piece. Difficulties arise when cornering because a larger lane width is required during cornering. All-wheel drive vehicles are only possible for small tonnages due to the restriction to single tires. Even articulated forklift trucks in use are only suitable for low loads due to their unfavorable stability geometry, and their own weight and large dimensions are far too high for the lifting force.
  • the invention has for its object to improve a generic stacking vehicle in such a way that with a more favorable ratio of payload / dead weight and with free maneuverability, reliable stability is guaranteed even when the steering is turned.
  • the problem is solved by the features specified in the characterizing part of claim 1. Because the counterweight comes to rest on the rear carriage, the high-lying boom of the rear frame required in the known case can be omitted and the overall length can be shortened. With a relatively long lever arm up to the axis of rotation of the front wheels, there is sufficient free space so that the stacking vehicle can also be adapted to practically all loads by placing additional weights. The counterweight can reach over the axis of the rear wheels, which results in a long lever arm despite the relatively small wheel base.
  • the features of claim 4 provide increased stability when cornering and with off-center lifting loads.
  • the counterweight can be moved transversely in accordance with DE-OS 3 131 512, depending on the steering movement.
  • the size and the load of the counterweight are determined by the fixed and variable factors: load, front and rear car in connection with the triangle.
  • load For special requirements on the stacking vehicle in relation to the narrow vehicle width and / or strong steering angle, the displaceability of the counterweight is expedient.
  • the calculations for the location of the centers of gravity are based on a stacking vehicle with a lifting force of 250 kN at a lifting height of 5 m and a load center of gravity from the front axle of 2.5 m.
  • the empty weight is 40 t.
  • the articulated all-wheel-drive stacking vehicle has a front end 20 with a lifting mast 22 and a lifting load 23 that can be moved up and down, a driver's cab 24 and a counterweight 14 protruding towards the rear with roundings 15 corresponding to the outer curve radius.
  • the front end 20 is connected to the rear end 26, which comprises the motor unit (not shown), via a vertical articulated bearing 28 with a vertical articulation axis located under the rear of the driver's cab 24.
  • the lifting weight 23 is arranged to the side of the central plane and nevertheless a stable balance is maintained, as the triangle in connection with the center of gravity diagrams illustrates.
  • the triangle is characterized by the connection of points 1, 2 and 3.
  • the reference number 4 denotes the center of mass of the front end
  • 7 is the center of mass of the load
  • 9 is the center of mass of the counterweight 14
  • 10 indicates the center of mass of the combination front end counterweight
  • 11 is the center of mass of the rear end
  • 12 is the center of mass of the Empty device
  • 13 is the center of mass of the vehicle plus the load 23.
  • the center of empty device mass 12 can be moved even further into the center of the standing triangle in any operating position.
