Definitions

  • the present invention relates to a lifting vehicle for stacking loads at high heights, comprising a wheeled chassis provided with a lifting mast, a driver's place mounted on the chassis and positioned transversely to the driving direction of the vehicle, and a load carrier for stacking loads, said carrier being movable along the lifting mast and capable of being manouvered from the driver's place for loading and offloading purposes.
  • One type of lifting vehicle of the aforedefined kind is often referred to as a sliding frame truck, which is used for handling pallet-carried goods in storage locations.
  • the goods are normally stacked on pallets and when the goods are to be shifted, the forks of the truck are brought into alignment with the pallet directly from the driver's place, by driving the truck to a correct position at right angles to the goods in question and raising or lowering the forks into the correct position for lifting/lowering the goods.
  • Such trucks work at high lifting heights, often heights of up to 10-12 m, which requires a high degree of accuracy on the part of the truck driver.
  • the driver's work is also made more difficult by the fact that a greater part of his forward vision is obstructed by the truck frame or the mast, which must be powerfully dimensioned because of the high lifting heights involved. Furthermore, such storage locations are poorly illuminated, in order to cut down on costs. Although this poor lighting can be compensated for by fitting headlamps to the fork assembly, there are many instances when headlamps are not provided, despite the poor visibility.
  • Another problem connected with positioning the fork assembly is that the driver's place is situated at right angles to the longitudinal axis of the truck and therewith also at right angles to the length extension of the forks.
  • one object of the present invention is to provide a lifting vehicle of the kind defined in the introduction with which problems associated with uncomfortable inclination of the driver's head and poor visibility are avoided to a significant extent. Further objects of the invention and advantages afforded thereby will be apparent from the following description. These objects and advantages are realized by a lifting vehicle having the characteristic features set forth in the following claims.
  • the present invention provides a lifting vehicle of the aforedescribed kind which includes a tilting device by means of which the driver's place can be tilted to different position in relation to the vehicle chassis, more specifically between a so-called normal truck driving position and a tilted, high-lift position.
  • the tilting device is constructed conveniently to tilt the driver's place about an axle arranged along one long side of the truck, so that when the driver's place is tilted rearwardly the driver will be located slightly outside the truck confines. Furthermore, tilting of the driver's place and the height to which the load carrier is lifted may be mutually coordinated and, although not necessarily, made directly proportional so that the driver's place will be tilted to a maximum at the time the load reaches its highest position.
  • the illustrated vehicle is an industrial fork-lift truck, and more specifically a sliding frame truck of the kind mentioned in the introductory part of this specification.
  • the truck includes conventionally a wheel-carried chassis 11, a chassis-mounted lifting mast 12 and a driver's place 13 which is transversal to the longitudinal axis of the vehicle.
  • the lifting mast 12 or the frame is normally comprised of two or more telescopically arranged sections 14 and a load carrier 15 in the form of a lifting fork, which can be moved along the full length of the lifting mast.
  • the lifting fork 15 extends in the direction of the vehicle long axis and is intended to carry palleted loads 16.
  • the driver's place 13 of the illustrated embodiment includes a cabin-like construction which accommodates a driver's seat 17, a steering wheel 18 and other steering controls for manouvering the truck, and a driver protection frame structure 19.
  • the driver is placed so as to sit at right angles to the longitudinal axis of the truck and to the direction in which the truck is driven, and therewith also to the forward direction of the load carrying fork 15.
  • the entire driver's place or cabin 13 can be tilted about a tilting axle 20 by means of a tilting device 21, in the form of some appropriate lifting device.
  • the tilting axle 20 is placed rearwardly of the driver's seat 17 and extends along one long side of the truck.
  • the lifting device 21 will conveniently have the form of a hydraulic piston-cylinder device mounted between a first linch pin 22 mounted on the chassis and another linch pin 23 mounted on the cabin structure, in front of the driver.
  • the driver's place is tilted rearwardly at an angle of 30-40°, to the position shown in Figure 3, this figure also showing that the driver's head will then be located outside the plane of the long side of the truck, therewith affording the driver a better viewing angle without troublesome bending of the head.
  • the tipping device 21 may also have the form of some other type of hydraulic motor, or alternatively of some form of drive motor mounted in connection with the tilting axle 20, such that the rotary shaft of the motor and the tilting axle will essentially coincide.
  • the arrangement may also include guide means which function to adjust automatically the rearwardly inclined position of the driver's place in relation to the height to which the load carrier is raised. This setting, or adjustment, need not be directly proportional, but may vary from case to case, so that different drivers are afforded the best possible comfort.
  • This automatic accompanyment of the hydraulic lifting device may conceivably be achieved by coupling a hydraulic pump in parallel with the hydraulic pump conventionally provided with delivering working fluid to the lifting piston-cylinder devices (not shown) of the load carrier or fork 15.
  • the additional pump may be given a capacity in which the driver's place will be tilted rearwardly to a maximum when the load carrier has reached its highest point.
  • the lifting device may comprise a motor-driven ball screw and the tilting movement of the driver's place can be combined in some suitable manner with means which will enable the whole or parts of the driver's place to be swung to one side.
