  • this device is used to load and unload transport vehicles such as boats, freight wagons or truck trailers.
  • Such a device is known for example from the document US5971108A which discloses a lifting device comprising a pair of vertical pylons parallel to each other, each pylon comprising a leading end and a foot end.
  • the elevator device further comprises a mobile platform arranged to move between the leading end and the foot end of each tower.
  • Each pylon supports on its end end a toothed pulley connected by a motor transmission arm arranged to rotate the toothed pulley at a speed of rotation about a first fixed axis of rotation through the transmission arm, the toothed pulley the first pylon facing the toothed pulley of the second pylon.
  • Each pulley causing a chain engaged with the toothed pulley, which chain is connected to the apical face of the platform mobile and which, when the toothed pulley is rotated by the action of the motor, is driven by the latter inducing a movement of the platform between a loading level and a discharge level of the latter.
  • This constraint requires the repetitive adjustment of the position of the platform for each back and forth of the latter between, for example, the loading level of the boat and a loading level of the platform from a loading platform on the platform when loading goods from the dock to the boat.
  • Adjustment can also be made when unloading goods from the boat to the dock, between the unloading level of the boat and a platform unloading level on the platform of the dock.
  • This adjustment is generally tedious and time consuming because it requires the vigilance of the operator who must ensure control of the engine while keeping attention to the movement of descent or rise of the mobile platform.
  • this adjustment is achieved by performing a descent movement of the platform which is adjusted by jerk to avoid any collision between the mobile platform and the boat.
  • a jerky movement of the platform can be the source of constraints that are generated in response to jolts and that act directly on the chain.
  • constraints can also act on the merchandise loaded on the platform and which can also be damaged.
  • these constraints can also act on the merchandise loaded on the platform and which can also be damaged.
  • these jolts are too large amplitude, there may be tilting of the goods, which also constitutes a non-negligible risk of accident.

  • the elevator device makes it possible to adapt in real time the speed of descent of the platform and to modulate this speed when the platform approaches the level of loading or unloading of the boat, that is to say when the distance between the platform and the first position, which first position corresponds to the level of loading or unloading of the boat, corresponds to a height equal to or less than the second predetermined threshold height.
  • the device according to the invention is characterized in that said pylon supports, at a second level located below said first level, a second pulley, in free rotation, to form a first pair of pulleys interconnected by said first transmission means, said transmission means having a second end connected to said base face of said platform which closes said first transmission means, said first transmission means being arranged to move said platform and drive said second pulley when said first pulley is rotated.
  • the first pulley when the first pulley is rotated, for example in the direction of clockwise, it exerts a pull down on the transmission means and a voltage proportional to the speed of rotation. rotation of the pulley facing the second pulley is generated from the second end of the transmission means connected to the basal face of the platform. This tension initiates the descent of the platform which is translational movement downward.
  • the downward movement of the movable platform is then governed by rotating the first pulley at a rotational speed and more by gravity alone.
