On a représenté, sur la figure 1, le mât de charge 1, d'un chariot élévateur, avec son tablier coulissant 2, équipé de deux bras 3 formant fourche de saisie de charge. Le tablier 2 est constitué de deux réglettes parallèles 5 et 6 sur lequel est adapté un support 7 conforme à l'invention. Sur le support 7 est montée une potence 8 avec fût 80, pied de fût 81 et flèche 82.There is shown, in Figure 1, the load mast 1, of a forklift, with its sliding deck 2, equipped with two arms 3 forming load capture fork. The apron 2 consists of two parallel strips 5 and 6 on which is adapted a support 7 according to the invention. On the support 7 is mounted a bracket 8 with barrel 80, leg of barrel 81 and arrow 82.

Le support 7 est constitué d'un plateau supérieur 70, d'une plaque 71 à angle droit avec le plateau, et d'un logement 72 recevant le pied 81 du fût de la potence 8. Le plateau supérieur 70 est percé d'une ouverture 73 pour le passage du fût 80. Dans le plateau 70 est ménagée une rainure 74 dans laquelle est engagée une nervure 50 de la réglette supérieure 5. Sur une plaque 10 est montée une électro-pompe 75 pour la manoeuvre de la potence indépendamment des moyens de mise en oeuvre du chariot élévateur. Les connections électriques et hydrauliques n'ont pas été représentées. Le bas de la plaque 71 s'engage entre deux butées 61 et 62, soudées sur la réglette inférieure 6. On constate ainsi que le support de l'invention 7, équipé de la potence 8, est en place sur le tablier 2 sans boulonnage ni soudure et qu'il peut donc être facilement posé ou enlevé. Dans la forme de réalisation représentée, le logement 72 est constitué par un groupe de deux vérins rotatifs 9 (figures 4, 5 et 6). Chacun est du type à double effet symétrique. Il comprend un corps creux cylindrique 90 dans lequel se meut une tige de piston 91 munie à ses extrémités de deux pistons de poussées 92 et 93. A chaque extrémité un orifice 94 permet l'arrivée du fluide. Un limiteur de course 95, réglable par écrous et contre-écrous, permet de limiter le déplacement du piston. La tige 91 est munie d'une crémaillère engrenant sur une roue dentée 97 solidaire, par tout moyen convenable, de l'arbre 98 de la potence 8.The support 7 consists of an upper plate 70, a plate 71 at right angles to the plate, and a housing 72 receiving the foot 81 of the stem barrel 8. The upper plate 70 is pierced with a opening 73 for the passage of the barrel 80. In the plate 70 is formed a groove 74 in which is engaged a rib 50 of the upper strip 5. On a plate 10 is mounted an electro-pump 75 for the operation of the stem independently of the means of implementation forklift artwork. The electrical and hydraulic connections have not been shown. The bottom of the plate 71 engages between two stops 61 and 62, welded to the lower strip 6. It can thus be seen that the support of the invention 7, equipped with the bracket 8, is in place on the deck 2 without bolting no welding and that it can therefore be easily installed or removed. In the embodiment shown, the housing 72 is constituted by a group of two rotary cylinders 9 (Figures 4, 5 and 6). Each is of the double-acting symmetrical type. It comprises a cylindrical hollow body 90 in which a piston rod 91 moves, provided at its ends with two thrust pistons 92 and 93. At each end an orifice 94 allows the arrival of the fluid. A stroke limiter 95, adjustable by nuts and locknuts, makes it possible to limit the displacement of the piston. The rod 91 is provided with a rack meshing on a toothed wheel 97 secured, by any suitable means, to the shaft 98 of the bracket 8.

Le chariot 4 comporte une plaque de base 40 en forme de V, montée sur trois roues orientables 41, un mât 42 et un plateau 43. Le plateau 43 est équipé de deux guides latéraux 44 et 45 et d'une cale 46. Au voisinage du sommet du mât 42 un bras 47 comporte un crochet 48. Un timon repliable 49 permet la manoeuvre du chariot 4.The carriage 4 comprises a V-shaped base plate 40, mounted on three steerable wheels 41, a mast 42 and a plate 43. The plate 43 is equipped with two lateral guides 44 and 45 and a wedge 46. In the vicinity from the top of the mast 42 an arm 47 has a hook 48. A folding drawbar 49 allows the carriage 4 to be maneuvered.

L'enlèvement du support 7, équipé de la potence 8, du chariot élévateur et sa pose sur le chariot mobile 4 s'effectue en exécutant les opérations suivantes :

  • a) ramener le mât de charge 1 à la verticale
  • b) rentrer les éléments télescopiques de la flèche 82 de la potence 8
  • c) effectuer une rotation de 900 de la flèche 82 pour l'amener à la position transversale
  • d) présenter le support 7 face aux guides latéraux 44 et 45
  • e) descendre le tablier du chariot élévateur jusqu'à pose du support 7 sur le plateau 43, et calage par la cale 46.
The removal of the support 7, equipped with the bracket 8, of the forklift and its installation on the mobile carriage 4 is carried out by performing the following operations:
  • a) bring the mast 1 vertically
  • b) retract the telescopic elements of the boom 82 of the bracket 8
  • c) rotate 90 0 of arrow 82 to bring it at the transverse position
  • d) present the support 7 facing the lateral guides 44 and 45
  • e) lower the deck of the lift truck until the support 7 is placed on the plate 43, and wedging by the wedge 46.

La sûreté de la pose est assurée par l'accrochage sur le crochet 48.The safety of the installation is ensured by the attachment to the hook 48.

On constate que ces opérations peuvent être faites, sans aide extérieure, par le mécanicien du chariot élévateur.It is noted that these operations can be done, without outside help, by the mechanic of the forklift.
