  • Trolley for handling and lifting an appliance so that it can be installed in a high structure, particularly a ceiling
  • the present invention relates to a trolley for handling and lifting an appliance so that it can be installed in a high structure, particularly a ceiling.
  • the procedure is generally as follows: First of all, in a first step, the appliance needs to be transported to the room in which it is to be fitted. Depending on the type of appliance, and particularly on its weight and bulk, such appliances may be carried by operators or moved around on transport trucks or trolleys. Such trucks or trolleys are well known and may for example consist of a four-wheeled truck or trolley, comprising a loading platform running horizontally near ground level, and a handle so that an operator can manoeuvre them or more particularly so that he can push or pull them. In order to carry out the installation step, it is then necessary, in a second step, to transfer the appliance onto lifting means so that it can be raised into a raised position level with the ceiling in which it is to be installed.
  • a second step to transfer the appliance onto lifting means so that it can be raised into a raised position level with the ceiling in which it is to be installed.
  • the lifting means may; for example, consist of forklift trucks, comprising forks running laterally and mounted secured to a telescopic structure able to deploy vertically from the floor in the manner of a ladder and moved by mechanical or electrical means.
  • Such lift trucks are generally heavy, bulky and difficult to steer, which means that it is difficult, if not sometimes impossible, to use them in premises such as office buildings.
  • the lifting means may also consist of rams, at the upper ends of which there is fixed a horizontal table and at the lower ends of which there are legs providing the connection with the ground, it being possible for the legs to be fitted with casters to form a mobile entity.
  • the appliances are, for example, units of the air- conditioner or convection fan type
  • these steps and the various operations require the presence of at least two operators, particularly for transferring the appliance onto the lifting means. This is because the weight of such appliances is generally of the order of some 30 kilos and sometimes up to some 50 kilos in the case of appliances containing heat pumps.
  • the invention aims to remedy these problems and disadvantages by proposing a solution that is simple, effective and economical.
  • the invention proposes a trolley for handling and lifting an appliance, characterized in that the trolley comprises, at its upper part: a horizontal lifting table, which is connected in terms of vertical movement to telescopic manoeuvring means for manoeuvring it between a lowered, loading, position and a raised, installation, position, and horizontal rolling means, which are arranged in the upper face of the lifting table and/or of the upper part of the trolley.
  • the trolley according to the invention constitutes a self-contained work station that makes it possible, in complete safety, to quickly install appliances and, to do this, requires just a single operator, regardless of the weight of the appliances.
  • an installation device comprising a trolley according to the invention is very ergonomic, allowing, amongst other things, a significant reduction in the effort needed to carry out manoeuvres and therefore in the extent to which the operators become tired.
  • the telescopic manoeuvring means are connected to a power source carried on board the trolley, which, being mobile, can then easily be moved around in premises so that appliances can be installed in succession, with the benefit of offering an improvement in productivity.
  • the trolley according to the invention makes it possible in general to optimize the conditions under which such appliances are installed by allowing significant improvements both in terms of time and in terms of the number of operators, and doing so while at the same time improving the working conditions of the operators in terms of ergonomics and safety.
  • the distribution and arrangement of the elements that the trolley comprises are dependent on their masses so as to bring the centre of gravity of the trolley down as close as possible to the floor, thus improving its stability.
  • the rolling means of the table and/or of the trolley are adjacent to at least one of the edges of the upper part of the trolley so as to allow the appliance to be transferred from an external support onto the lifting table in the loading position;
  • the rolling means of the lifting table comprise rolling elements which are housed in the table; - the rolling elements automatically retract under the upper face of the table when the table leaves its loading position;
  • the rolling means comprise at least one roller which is mounted on the upper part of the trolley between an edge of the upper part and an edge of the lifting table;
  • the rolling elements of the lifting table and the rollers are mounted so that they rotate about axes that are roughly parallel;
  • the telescopic manoeuvring means for manoeuvring the lifting table comprise at least one ram, such as a pneumatic ram, and a pressurized-fluid source; -

  • the hooks 550 fit over the catching bar 150 of the trolley and then the operator advantageously makes use of the cooperation between the catching means 550 and the bar 150 as a pivot, exerting a pushing force axially forwards so that the casters 513 leave contact with the ground.
  • the two-wheeled handcart 500 is then locked to the trolley 10 in such a way that it cannot tilt backwards and that the casters are no longer in contact with the ground.
  • the handle is lowered back down into the lowered position until the ends of the locking bar 530 come to bear against the stop means 535 of the trolley, more precisely against the front vertical face of these means.
  • the two-wheeled handcart 500 is then placed on board and hooked onto the trolley in a position known as the position of use.
  • the trolley 10 is then a completely self-contained workstation because the pressurized-fluid source for the lifting means is carried on board and productivity is thus enhanced when installing successive appliances.
  • such a compressed-air cylinder could be housed in the rear part of the trolley 10, or alternatively, four smaller cylinders could be housed one at each of the corners of the trolley 10, along the members 1 15.
  • the accumulator such as a cylinder
  • the trolley between its upper 20 and lower 40 platforms, it is possible to house the accumulator at an angle in the rear part of the trolley, which then has an opening in its upper platform and means for immobilizing the upper part of the cylinder and a receptacle similar to that of the ram formed in the lower platform to accommodate the lower part of the cylinder.
  • the operator may, for example, insert it from above.
  • the trolley 10 comprises stabilizing means such as legs, which may be mounted retractably or, alternatively, such that they can be removed.
  • the front 142 and rear 144 transverse members of the lower frame 140 of the chassis are preferably made of metal tubes of square section which open laterally so that another element belonging to the stabilizer means can be push-fitted into the interior section of the members.
  • the trolley 10 may be convertible.
  • the lifting table 60 may for example be replaced by tools, such as a drill, which are mounted securely to the end of the ram so as to constitute as electric and/or pneumatic drill of the pillar type.

Abstract

L'invention concerne un chariot (10) servant à manipuler et à lever un dispositif, de sorte que ce chariot peut être monté dans une structure élevée, en particulier, un plafond. Ce chariot est composé, de façon caractéristique, dans sa partie supérieure, d'une table de levage horizontale (60) accouplée afin d'effectuer un déplacement vertical, à des moyens de manoeuvre télescopique (80) servant à la manoeuvrer entre une position de chargement abaissée et une position d'installation élevée, et de moyens de roulement horizontal (70, 90) situés sur la face supérieure (62) de la table de levage (60) et/ou de la partie supérieure (20) du chariot.
