Definitions

  • the object of the invention is to create a device in order to be able to lift and move the entire load or only a part thereof on the loading surface of a vehicle or a fixed or mobile loading ramp, in order to achieve maximum versatility of the device and the adaptability thereof to achieve the type of cargo and / or use.
  • the invention proposes to provide several rows of rolling elements on a single lifting system and to arrange several sliding elements with respect to these on the corresponding loading area, which can run synchronously in order to move the entire load or which can be operated independently of one another to move only part of the load. Furthermore, the invention does not rule it out, for example, on the same loading area. before providing several lifting mechanisms that are independent of one another so that only a part of the load can be lifted and moved.
  • the rows of the rolling elements are idling mounted on frames which are vertically adjustable vertically by one or more rows of interconnected hydraulic cylinders.
  • the rolling elements In the lowered position of the rolling elements, that is to say with the load resting on the loading level, they do not protrude beyond the loading level, while in the extended position they protrude beyond this level and raise the load, which can be shifted by chains; these run in grooves provided in the loading area and have teeth or profiles protruding therefrom.
  • the chains move in the transverse direction to the axes of rotation of the rolling elements. In the case of several chains, it is possible to operate them synchronously or, if only part of the load is to be shifted, to operate them individually.
  • Fig. 1 shows a cross section through a loading area for two parallel loading areas with a lifting device provided with two rows of hydraulic cylinders.
  • Fig. 1a is a plan view of part of the in
  • Fig.1 shown loading area.
  • Fig. 2 shows a cross section through a loading area with two independent, parallel lifting and moving Devices, both with a series of hydraulic cylinders.
  • Fig. 3 shows a cross section through a loading area with a single lifting device and a single row of hydraulic cylinders.
  • FIG. 4 shows a diagram relating to the oil distribution for the device according to the invention.
  • the containers, the goods or the bales of goods are on the loading level 1, which over the longitudinal spars
  • bearing rails 8 for a number of idling rollers 2 are accommodated.
  • the bearing rails 8 with the rollers 2 are movable vertically, by means of a single connecting structure 3 (FIG. 1), 3b (FIG. 3) or by means of structure 3a (FIG. 2) divided into areas, on which a series of Hydraulic cylinder 4a, 4b acts or two rows of hydraulic cylinders 4 act, which are fastened to the fixed basic structure 5, 7.
  • rollers When the rollers are in the lowered position, they are located slightly lower than the loading level or are flush with it so that the load is placed on the loading surface before it is transported (transport position).
  • hydraulic cylinders 4,4a, 4b via the vertically movable 3, 3b connection structure for the bearing rails 8, the rollers 2a are moved out of the loading level, whereby the load is raised slightly.
  • This can thus be moved 6c on the rollers 2 by means of the chains 6c, which run in their own grooves, parallel to the bearing rails 8, and which have teeth 6a or profiles projecting from the loading level 1.
  • FIG. 3 shows a solution which enables the entire load to be lifted by means of a single row of cylinders 4b, while the shifting is carried out by two chains 6 running synchronously with connecting profile 6b.
  • the longitudinal bars 5 have corresponding recesses.
  • the retracting movement of the rollers 2 and the entire movable structure 8, 3, 3a, 3b can be achieved by springs which, together with the weight of the structure, press the oil out of the cylinders 4, 4a, 4b.
  • These springs can be attached, for example, between the rows of cylinders laterally or coaxially to them.
  • this is Volume of the oil contained in the individual connecting lines 10 between the cylinders 4 is greater than the volume of the maximum displacement of a cylinder.
