Abstract

The hoist is used for raising heavy water tanks which are to be fixed to a vertical wall. A main framework (7,9) mounted on castors (10) supports a hoist comprising a manual jack (6) connected by a cable (8) passing over pulleys (13) and supporting a cradle (1,2,3). The overall height of the frame is adjusted by a telescopic frame section (12). The water heater can be placed on the cradle (1) and raised to the desired position and attached to the wall by one operator. The manual hoist (6) can be replaced by an electric hoist.

Description

Cet appareil,un "Elévateur-Transporteur', est particulièrement étudié pour faciliter la mise en place des objets lourds et peu maniables,de forme quelconque,se fixant sur une paroi verticale et qu'un homme seul,de force moyenne,ne peut mettre en place,c'est le cas d'un chauffe-eau électrique par exemple. This device, an "Elevator-Transporter", is particularly designed to facilitate the placement of heavy and unwieldy objects, of any shape, fixed on a vertical wall and that a single man, of medium strength, cannot put in place, this is the case of an electric water heater for example.

Les engins connus de ce genre,sont du type " à sangles ". Known devices of this kind are of the "strap" type.

De tels dispositifs sont d'un emploi malaisé et manquent de précision ; en effet,pendant la manipulation,les sangles s'allongent sous l'effet de la charge à manutentionner.Such devices are difficult to use and lack precision; in fact, during handling, the straps lengthen under the effect of the load to be handled.

La figure jointe donne un exemple de la réalisation de l'invention. The attached figure gives an example of the embodiment of the invention.

L'élévateur se compose d'un ensemble cadre (1) palonnier (2) réunis par des chaines (3) suspendues à des tiges filetées (4) terminées par des crochets où l'on passe le maillon choisi en fonction de la hauteur de l'objet. La tension des channes (3)- et de ce fait,le serrage de l'ensemble - se termine en vissant les écrous à oreilles (5) disposés sur les tiges filetées (4) qui traversent le palonnier (2). Le tout est pendu à un treuil à main (6) fixé sur un portique comprenant deux éléments télescopiques (7 & 2)s
- l'élément inférieur (7) muni d'un treuil manuel (6) à cable (8) est fixé sur un cadre (9) porté par quatre roulettes orientables (10) et dont un des côtés (11) est amovible afin de faciliter la prise de la charge par le portique (7 & 2).The elevator consists of a frame assembly (1) lifter (2) joined by chains (3) suspended from threaded rods (4) terminated by hooks where the chosen link is passed according to the height of the object. The tension of the chains (3) - and therefore the tightening of the assembly - ends by screwing the wing nuts (5) arranged on the threaded rods (4) which pass through the lifter (2). The whole is hung from a hand winch (6) fixed on a gantry comprising two telescopic elements (7 & 2) s
- The lower element (7) provided with a manual winch (6) with cable (8) is fixed on a frame (9) carried by four orientable rollers (10) and one of the sides (11) of which is removable in order to facilitate load taking by the gantry (7 & 2).

- l'élément supérieur (12) portant les deux poulies à gorge (13) nécessaires au guidage du cable (8) du treuil (6),se positionne à la demande par broches (14) sur l'élément inférieur (7). - The upper element (12) carrying the two grooved pulleys (13) necessary for guiding the cable (8) of the winch (6), is positioned on request by pins (14) on the lower element (7).

Le cadre (1) est muni de protections (15) et il suffit de glisser une garniture souple (chiffons) entre les chatnes (3) et l'objet à manipuler avant le réglage définitif des channes (3),pour éviter le frottement de celles-ci sur son revêtement. The frame (1) is provided with protections (15) and it suffices to slide a flexible lining (cloths) between the pins (3) and the object to be handled before the final adjustment of the chains (3), to avoid friction of these on its coating.

Le portique (7 & 2) est réglé en fonction de la hauteur de fixation de l'objet. Celui-ci étant saisi dans l'ensemble cadre-palonnier (1 & ) ce dernier accroché au cable (8) du treuil (6),on place le quatrième côté (11) du cadre (9),qui évitera, au cours du déplacement,la déformation de ce dernier lors du blocage intempestif d'une des roulettes (10) par exemple. The portal frame (7 & 2) is adjusted according to the object's mounting height. The latter being gripped in the frame-lifter assembly (1 &) the latter hooked to the cable (8) of the winch (6), the fourth side (11) of the frame (9) is placed, which will avoid, during the displacement, the deformation of the latter during the untimely blocking of one of the rollers (10) for example.

La charge décollée du sol,l'appareil peut alors être déplacé et prendre position en face de l'emplacement prévu de mise en place de I'objet. With the load lifted off the ground, the device can then be moved and take up position opposite the planned location for placing the object.

D'un maniement aisé,le treuil (6) permettra le positionnement avec précision. Easy to handle, the winch (6) will allow positioning with precision.
