  • the platforms are able to be connected to a telescopic lifting arm, with which the work machines are provided, by means of attachment devices.
  • the known platforms work very effectively when used for work activities at height which require manual intervention by the operators, possibly with the use of portable tools which, as mentioned, can be easily loaded on the platform.
  • the operators moving on roofs of buildings remove the slabs of the cladding and position them resting on a pallet lifted by a crane or by the forks of a telehandler, which pallet is periodically lowered to the ground surface for the transfer of the removed slabs towards the bed of a truck or the like.
  • US5992562 discloses a scissor lift control system including a around control station, located on the base portion of the work platform, and a platform control station.

  • the two devices 41, 42 are located at two internal corners of the platform 1, in particular the corners defined at the lateral ends of the side wall 12 opposite the mobile side wall; however, this is not a mandatory solution.

  • Selections of the interface also refers to the choice not to act on the interface; in detail, if the enabling devices 42, 43 are provided with buttons 421, 422, 431, 432 and they are not pressed, then a normal operating condition is selected.
  • the processing unit comprises an enabling module configured for enabling control of the hydraulic distributors activating the arm 21 alternatively by the command apparatus 41 on-board the platform 1 or by the command apparatus in the cabin, according to what has been selected or not selected on the enabling devices 42, 43.
  • an aim of the system of the invention is to allow that, during the use of the platform 1 for special activities such as removal of a cladding (for example an asbestos cladding), command of the movement of the arm 21, and therefore the displacing of the platform 1, is entrusted to the operator in the cabin and not the operators 31, 32 on the platform 1.
  • the arm is commanded by the apparatus located on-board the platform, as the operators on the platform have direct vision of the environment surrounding the platform itself, for example the roof of a building, which the operator in the cabin does not have.
  • the invention can also include the possibility of an exceptional operating condition in which the command of the arm 21 can be taken over by the operators 31, 32 on-board the platform 1, as is more fully explained in the following.
  • the processing unit and in particular the enabling module thereof is configured either to enable or disable the command of the activating apparatus by the first 41 or the second command apparatus, also according to the checks carried out by the detecting device 51, 52, i.e. depending on whether the platform 1 is in the normal configuration or in the special use configuration.
  • the processing unit receives the above-described first or second command signals, the configuration signals from the switch 52 (or other device suitable for the purpose) and enabling signals from the enabling devices 42, 43 and, according to these, processes driving signals which are transmitted to the distributor(s) which activate the cylinders of the arm 21.
  • each enabling device 42, 43 includes buttons 421, 422, 431, 432, preferably two in number.
  • Pressing on a first button 421, 431 selects a first enabling condition while pressing on the second button 422, 432 selects a second enabling condition, alternative to the first; in practice, on the basis of the pressure exerted on the buttons of the enabling devices 42, 43 the command of the arm 21 can be established or switched by the command apparatus 41 of the platform 1 or by the command apparatus separate from the platform 1 and located in the cabin 23.
  • the invention envisages that the processing unit enables control of the arm 21 by the apparatus in the cabin, disabling the apparatus on the platform 1, if both the platform 31, 32 operators have contemporaneously pressed or continue to press the first button 421, 431 of the relative enabling device 42, 43.
  • the interface of the enabling device 42, 43 is adapted to enable an operator 31, 32 to select at least a first enabling condition; when said first enabling condition is selected, the enabling module of the processing unit enables the second command apparatus (separate from the platform 1) to command the activating apparatus (constituted by one or more distributors) and at the same time disables the first command apparatus 41.
  • the enabling module is configured to enable the second command apparatus to command the activating apparatus and to disable the first command apparatus 41, once said first enabling condition is selected in both the enabling devices 42, 43 located on-board the platform 1.
  • the enabling module is preferably configured for enabling the first command apparatus 41 to command the activating apparatus, only if the detecting device 51, 52 has checked that the platform 1 is in the second working configuration, i.e. the one for special use of the platform.
  • the enabling module enables the first command apparatus 41 to command the activating apparatus while disabling the second command apparatus.
  • the platform 1 of the invention can be used like any other platform.
  • the command of the arm 21 is exclusively entrusted to the operators 31, 32 on-board the platform 1 who use the joystick and the buttons or other interface means of the above-mentioned first command apparatus 41.
  • the platform 1 is to be employed for special uses, such as the removal of asbestos roof claddings, before use the platform 1 must be opened, i.e. the mobile side wall 11 must be tilted, creating a lengthened bottom plane 10, 110 at the base of the platform 1.
  • the opening of the mobile side wall 11 activates the switch 52 which transmits the above-mentioned configuration signal to the processing unit, which thus receives the information that the platform 1 is in the working configuration for special uses.
  • the operators 31, 32 represented in a stylised way in the figures, board the platform 1 and move to a respective enabling device 42, 43, in order for both of them to press the above-mentioned first button 421, 431, which selects the first enabling condition.
  • the processing unit disables the use of the first command apparatus 41, authorising only the second command apparatus located in the cabin only to move the lifting arm 21 on activation of the distributor or the hydraulic distributors.
  • the two operators 31, 32 can remove the claddings and bring them on-board the platform 1.
  • the platform 1 of the invention further comprises two hooking rods 61, 62, preferably curved in a hook shape, to which it is possible to anchor retaining cables (not illustrated for the sake of clarity in the figures) connected to the suits or to a harness worn by the operator 31, 32 working on the platform 1.

  • rods 61, 62 can be blocked in various angular positions to facilitate use thereof.
  • the operators 31, 32 newly approach the enabling devices 42, 43 and both press the first button 421, 431 to enable the operator in the cabin to return the platform 1 to the ground surface, together with the material to be unloaded.
  • the platform 1 In a case in which the operators 31, 32 are at height and for some reason the cabin operator is not able to activate the arm 21, for example because he has left the cabin, it is possible for the platform 1 to be lowered and the two operators 31, 32 to the ground surface in the following way.
  • One of the platform 1 operators 32 goes to one of the enabling devices 42, 43 and presses the second button 432, 422.
