  • the platform (1) for working in elevator shafts (2) of the invention comprises:
  • the extensible legs (3) comprise (see figs 3, 4 and 5):
  • the lower fixed ladder (30) has an outer width equal to or less than the inner width of the upper extendable ladder (31) to be partially accommodated in said upper extendable ladder (31) and reduce the space occupied in the folded position.
  • the lower fixed scale (30) preferably has a height between 1 meter and 1.20 meters (very preferably 1.10 meters) and the upper extensible scale (31) has a maximum external width of 65 centimeters for access to narrow openings (2) characteristic of existing buildings under renovation and replacement where, currently, operators of different companies around the world tend to operate from a ladder in an unsafe way to install guides.
  • the upper extensible work surface (6) comprises:
  • the second implements arranged at the end of the extensible longitudinal beams (64) can be for example:
  • the extensible longitudinal beams (64) are ideally located inside the fixed longitudinal beams (63) (between them as seen in figs 5 and 7) and comprise some sleepers (68) (see fig 5) to keep their spacing and ensure good support of the plates (66, 67), the fixed longitudinal beams being connected at their ends by means of end plates (69) for the same purpose.
  • the locking elements for the extension of the work surface (6) may advantageously comprise (see figs 8 to 10) a first spindle (800) (which can be seen in better detail in fig 9) which is located relating at least one of the end plates (69) of the fixed longitudinal beams (63) and one of the sleepers (68) of the extendable longitudinal beams (64) of the extendable upper work surface (6) to produce, not only the blocking, but also a tightening that minimizes movements due to slack and increases safety, with the additional advantage that it serves to extend the longitudinal extensible beams (64).
  • said first spindle (800) comprises (see fig 9) a first threaded rod (802), a first double thread (803)
  • the distal end plate (69) of the fixed longitudinal beams (63) comprises a hole (801) (see fig 8) for the passage of the stem (802) of said first spindle (800) in folded or not fully extended positions of the extensible longitudinal beams (64).
  • the elements for blocking the opening between the legs (3) and the work surface (6) may comprise - with the same purpose and advantages as in the case of the first spindle (800) - a second spindle (806 ) that is connecting, through articulated joints (807, 808) (see fig 10), the proximal end plate (69) of the fixed longitudinal beams (63) of the extensible upper work surface (6) and the step top (31 1) of the extendable ladder (31) top of the extendable legs (3).
  • the use of the articulated joints (807, 808) allows the folding movements and the adjustment of the width of the opening between the legs (3) and the work surface (6).
  • the second spindle (806) comprises (see fig 10) a second threaded rod (809), a second double thread (810) arranged in a first articulated joint (807) fixed to the end plate (69) proximal of the fixed longitudinal beams (63) of the upper extensible work surface (6), and a second opposing support bushing (81 1) arranged on the upper rung (31 1) of the extensible ladder ( 31) top of the legs (3) extensible through a second articulated joint (808); the second rod (809) comprising a second machined end (812) (see in fig 9) on the opposite side of the second support bushing (81 1) (also hexagonal) for actuation by means of a tool.
  • the second stem (809) also ideally comprises a distal stop (813) to prevent it from coming out of the second double thread (810).
  • the extensible set of plates comprises (see figs 5 and 7) in the preferred embodiment a first plate (66) fixed at its proximal end to the fixed longitudinal beams (63) or to its proximal end plate (69), and a second plate (67) fixed at its distal end to the extensible longitudinal beams (64) or their cross members (68), said plates (66, 67) having a length equal to or less than that of the folded work surface (6) so that they can overlap in this case and in the folded position they are gathered up favoring transport. Furthermore, provision has been made for skirting boards (70) and perimeter handrails (71) on its sides and bottom (of the work surface (6)) to prevent objects from falling from below and to secure the operators.
  • the plates (66, 67) are independent and are removably fixed to the beams (63, 64), proximal end plate (69) or corresponding cross members (68) to facilitate positioning of the platform (1) of the invention within of the hole (2).
  • the operator places the structure in the hole without the trays or handrails with an approximate weight of 15 Kg, eliminating weight, and therefore, reducing the risk of being able to fall into the hole due to the expiration of the weight of the platform elements .
  • the first plate (66) and handrail (71) of its area will be placed from the landing and finally the second plate (67) and the handrails (71) of its area, as seen in the sequence of views in fig 7 .

  • the first implements (4) very preferably comprise angle plates, from one of whose planes the legs (3) emanate outwards. This allows them to be placed at the angle of a slab or beam edge, keeping the opening angle between legs (3) and work surface (6) above 90 degrees.
  • wheels (40) and handles (41) has been provided to facilitate wheeled transport in the folded position.
  • Said (40) wheels can be arranged on the first implements (4).
  • the locking elements can comprise pins (8) that interlock in holes (81) of the parts to be immobilized.
  • the same platform can be used for the mounting of guides from above the chassis, either gantry or backpack type by coupling a longer ladder kit to access from the base of the cabin, and regardless of the dimensions of elevator car and nominal load.
  • several platforms can even be inserted in the shaft and in the chassis at the same time.
  • the structural elements are innovative by combining the technology of the portable telescopic aluminum ladders with their corresponding steps, with the extendable work platform in extruded aluminum that does not exist on the market to reduce the weight of the work tool.
