Definitions

  • the present invention proposes a platform to be mounted on a lifting and/or transporting apparatus.
  • the peculiarity of this platform apparatus is to include moving means provided with an extensible structure.
  • the platform according to this invention is mounted on an end of a lifting and/or transporting apparatus, an extensible structure being placed between the platform and the apparatus.
  • the extensible structure permits to really improve the movement of the basket. As a result of this, the operator can work in a better way by utilizing the said platform.
  • the said lifting and/or transporting apparatus includes any fixed and movable apparatus, which may be extensible or not, such as telescopic arms or articulated arms, rotary and fixed apparatuses, vehicles of any kind, etc.
  • the present apparatus has been conceived to improve the operation of lifting structures for persons and/or things, such as aerial platforms that may be fixed and/or movable, translating or non-translating, positioned on vehicles and/or land structures or ships or aircrafts.
  • aerial platform that may be used in many cases such as in building field: restoration of building fronts, balconies, frontals and cornices, treatment of frameworks, reinforcements and scaffoldings, wall painting, waterproofing process, specific utilization of mortar, urgent demolitions of tottering parts, change and/or repair of channels and drain-pipes, internal and/or external upkeep or maintenance of silos, reservoirs and so on.
  • the aerial platforms consist of a crate or basket that is mounted on an end of a lifting and/or transport apparatus.
  • Most lifting and/or transport apparatuses are provided with a telescopic arm or an articulated arm or the like.
  • a telescopic arm or an articulated arm or the like For the utilization of the basket it is necessary that an operator gets in and uses the basket instruments to reach the operative position. The operator must use the wires of the telescopic or articulated arm and/or the other instruments provided on the basket.
  • a problem of the said conventional systems consists in a limited range of the movements to be actuated by the operator because the lateral or vertical displacement of the basket is obtained by moving the whole telescopic or articulated arm or the whole lifting equipment. As a result of this, there are practical, mechanical and operative difficulties and the wear and tear of the components of the said apparatus is very high.
  • the object of the present invention is to conceive and carry out a new system to lift and move a basket or crate of an aerial platform and adjust the operative positions of the basket.
  • the said system is provided with a bar showing a fixed and/or adjustable length which accomplishes translating and angular movements and is mounted on an end of a telescopic or articulated arm.
  • the bar supports slideably a basket or crate for the operator and therefore, the basket is translated in any direction without intervening on the telescopic or articulated arm or the lifting and/or transporing apparatus.
  • the said moving system permits a complete operation of 360 degrees of the basket and therefore, the resulting working area is 50% larger than the working area of the existing equipments on permitting to reach positions and sectors that the prior art apparatuses did not reach.
  • an aerial platform which is mounted on a movable arm or lifting and/or transporting apparatus, characterized in that it comprises moving means which consist of an extensible bar which is mounted in such a way as to accomplish translating and angular movements and is mounted on an end of a telescopic or articulated arm, and that the said bar has slide guides in which a carriage slides, which supports a basket in which persons or things are lifted or transported.
  • number 1 denotes an aerial platform on the whole to be mounted on a lifting and/or transporting apparatus, which platform includes the moving means according to the present invention which show an extensible structure.
  • the aerial platform 1 includes a basket 2 which is to carry persons or things.
  • the basket is mounted slideably on a bar 3 which in turn is mounted slideably and with the possibility of rotating angularly on an end of an arm 4.
  • the arm 4 is a telescopic arm or an articulated arm and is a part of a vehicle on which the system according to this invention is mounted.
  • the bar 3 is mounted on a support 5 which is provided with a motorized pivot 6 applied on an end of the telescopic or articulated arm in order to rotate angularly according a complete turn of 360°.
  • the support 5 is provided with a guide in which a bar 3 slides according to movements caused by a system which includes a motorized pinion 7. At least a chain 8 is applied through suitable chain wheel gears on the motorized pinion 7. The ends of the chain are fixed to the respective ends of the bar.
  • the motion of the chain is caused by the motorized pinion 7 and permits a complete movement of the bar in both directions while the motorized pivot 6 causes a complete angular displacement.
  • the bar 3 is provided with suitable slide guides along which a carriage 9 (Fig. 3) is translated.
  • the basket 2 is mounted on the carriage 9 to carry persons or things.
  • the carriage 9 may be translated for the whole length of the bar through a mechanism of displacement which includes a motorized pinion 10 on which a chain 11 is winded, the ends of the chain 11 being fixed to the bar through return pulleys 12.
  • the basket 2 is mounted on the carriage 9 through a joint 13 and an articulation 14.
  • the joint is to adjust the basket on a horizontal axis while the articulation 14 is to adjust the basket on a vertical axis. In this way, it is possible to guarantee the maximum possibility of levelling and rotation of the basket according to the movement of the arm.
  • the carriage 9 is provided with a thrust ring or similar articulation 15 which permits to obtain a complete angular vertical adjustment of the carriage of 360° about itself.
  • the system is provided with sensors to detect the position of the basket and adjust constantly the position of the basket in respect of the ground so that the basket always maintains a perfect horizontal position.
  • the movements of carriage 9 and bar 3 may be independent and/or synchronized.
  • the described moving elements could be also of another type such as rack pinions, winches with ropes, hydraulic jacks, electric actuators, pneumatic systems and so on.
