Definitions

  • TECHNICAL HELD This invention relates to a lifting device and/or a method of lifting and has been devised particularly though not necessarily solely for use in lifting containers.
  • the present invention consists in a method of loading or unloading a transportable container onto or from a transporting vehicle therefor which comprises: engaging each corner region of the container with apparatus having a powered extendable/retractable leg; substantially synchronously lowering each leg to thereby engage a support surface (such as the ground) to cause the lifting of the container; moving the transporting vehicle, if unloading, from under the container, or, if loading, to be in a container transporting location under the container; substantially synchronously raising each leg to tend to disengage the support surface(s) thereby lowering the container onto the ground or onto the tr-insporting vehicle respectively; and disengaging said apparatus from each corner region.
  • each apparatus engages a corner region of the container with a portion that inserts vertically down into the top of the container and a lower region that inserts substantially horizontally into the container.
  • Preferably said apparatus can be moved from one wall to the adjacent wall about a corner of the container without removing the engagement into the top of the container provided the substantially horizontal engagement into the side of the container is momentarily disengaged.
  • each powered leg is actuable hydraulically and the powering of the hydraulic system is by means of a rechargeable storage battery carried by each of the four apparatus each of which is to be engageable to a corner region of the container.
  • each said apparatus to or from each corner region is performed using a carriage vehicle therefor.
  • said carriage vehicle is a vehicle having members capable of engaging sockets or male members of each apparatus in a complementary manner.
  • the synchronous lowering and/or raising is by the control of one of the apparatus (hereafter the "master apparatus") and the synchronous operation of the three remaining slave apparatus, a signal being directed to each of the slave apparatus by means of an electrical signal, a light or radio signal or a vibration.
  • the signal from the master unit of the apparatus is by radio signal.
  • a broadcast signal receivable by each one of the apparatus having an extendable/retractable leg ensures the synchronous control of the lowering and/or raising.

Abstract

Méthode de chargement ou de déchargement d'un conteneur d'un véhicule de transport. La méthode consiste à placer aux quatre coins du conteneur (3) un dispositif (1, 43) comportant un pied (2) extensible et rétractable animé par un moteur. Pour décharger le conteneur du véhicule de transport illustré à la Figure 5, les pieds (2) sont abaissés simultanément, de manière à appuyer sur le sol et, en conséquence, lever le conteneur (3). Le véhicule est alors retiré de dessous le conteneur (3). Selon une autre procédure, si le conteneur (3) doit être chargé sur le véhicule de transport, comme illustré à la Figure 5, la plate-forme du véhicule est introduite sous le conteneur (3), les pieds (2) étant déployés. Ces pieds (2) sont alors relevés simultanément de manière à ce que le conteneur (3) porte sur le sol ou repose sur la plate-forme du véhicule. Chacun des dispositifs (1, 43) est alors dégagé des coins du conteneur (3). L'invention porte également sur le dispositif permettant de charger ou de décharger le conteneur (3) du véhicule. Les quatre dispositifs de levage (1, 43) prévus comportent chacun un pied extensible (2) constitué par un ensemble cylindre piston. Chaque dispositif de levage (1, 43) comporte une clavette qui s'engage dans un orifice situé vers le haut du conteneur (3), un deuxième moyen de positionnement (20) permettant au dispositif de s'engager conre la partie inférieure du conteneur (3) et un pied (31) prenant appui sur le sol. Le système peut être utilisé pour déplacer des conteneurs (3).
