Definitions

  • the invention relates to removable access equipment for the production, by a qualified operator, of maintenance work on a high panel.
  • each support leg (21,22) comprising an upright (16) with panel-connecting means and a support rod (41,42) substantially perpendicular to the upright and fixed on a lifting support (17) sliding on the upright with a reinforcing structure for transferring the forces exerted on the support rod towards the upright, said bridge (2) comprising a platform (3) with a work plane (30) and base railing means (35,36,37,38) extending above the remote work plane of the workplan.
  • the removable equipment in question is characterized in that said bridge (2) comprises at least first and second locking means (51,52), each arranged under the platform and designed to cooperate with the first rod respectively. (41) and the second support rod (42), the locking being achieved by simply engaging when docking the locking means of the support rod, and a first unlocking control (50) located in the vicinity of one end of the platform, away from the locking means, said first unlocking control allowing the operator to simultaneously unlock the at least two locking means to uninstall the removable access equipment.
  • the locking being of the automatic type, this contributes to providing a safe and robust configuration for the coupling of the bridge on the jambs which are fixed to the panel.
  • Unlocking is controlled by a simple operation of the operator, the uninstallation is easy, fast and can be done safely. All operations present good ergonomics.
  • one or more of the following arrangements, in isolation or in combination, may optionally be furthermore employed.
  • first locking means 51,53
  • second locking means 52,54
  • the reinforcing structure of the lift support comprises a support arm (18) and a strut (19), the support rod (41) being connected to the arm by two or three struts (44,45, 46).
  • This configuration provides, thanks to the squareness link formed by the strut, a particularly effective reinforcement structure.
  • the support rod may be of round section. It is thus very easy to manufacture and the docking of the locking means is very reliable.
  • said bridge (2) extends in an extension direction (D1) and the platform (3) has first (28) and second (29) opposite longitudinal edges extending in the direction of extension (D1), with the work plane (30) between the first and second longitudinal edges, and transverse beams (24) under the work plane to which the locking means (51,52) are fixed.
  • the platform and its mounting system on the jambs are thus particularly robust.
  • cleats (48,49) on the support rod, said cleats being adjustable in position along the rod, thus providing a reference for the coupling of the platform on the rods.
  • a positioning aid along the X axis that is to say along the direction perpendicular to the display plane to adapt in particular to the more or less bulky configuration of the base of the panel. This also makes it possible to control the distances and tolerances tolerated with respect to the safety rules of personnel working at height.
  • a scale (8) with preferably in its upper part hooking means (80) of the ladder relative to the bridge. Thanks to this the operator can safely access the platform from the ground, both uphill and downhill.
  • the removable access equipment forms a kit (K) with the jambs, and if necessary the ladder, placed on and / or contained in the bridge, and said kit can be loaded in the cargo compartment a van, with preferably for the size of said kit a length slightly greater than 3 m, a lower width of between 0.5 m and 1 m (typically 0.75 m) and a lower height of between 0.5 m and 1 m (typically 0.75 m).
  • the bridge may further comprise a gantry crane which comprises a frame (99) provided with wheels (96), said gantry crane being movably mounted under the platform (3) between a folded position PRA, in which a frame (99) is placed near the platform, and a deployed position PDE in which a frame extends away from said bottom surface (33).
  • a gantry crane avoids the operator having to carry the bridge and jambs between the van and the place of the panel; moreover the retraction of the gantry at the time of introduction into the van makes the loading maneuver very easy and significantly reduce its size in height.
  • the wheels of the gantry make it possible to pass small obstacles such as a sidewalk, a kerf, or other irregularity of the ground on the path between the van and the place of the panel.
  • the gateway may further comprise a second unlocking command (90) for unlocking the deployed position (PDE) of the gantry crane to allow folding (Sr) of the gantry to the folded position (PRA).
  • a second unlocking command 90 for unlocking the deployed position (PDE) of the gantry crane to allow folding (Sr) of the gantry to the folded position (PRA).
  • the deployed position is a stable and locked position; so that maneuvers performed with taxiway ground running are carried out safely and that the folding of the gantry crane can be obtained only on an express action on the second unlocking control.
  • the first unlocking command (50) is arranged in the immediate vicinity of a gripping bar (20) of the gateway. This facilitates the operations of uninstallation of the gateway to be carried out by the operator.
  • the first unlocking control (50) and the second unlocking control (90) are arranged close to each other at a first end (2A) of the platform. This is very convenient to use and optimizes the movements to be performed by the user.
  • the frame (99) of the traveling gantry has an opposite end to the base pivotally mounted about a transverse axis (X9) on the platform (3), the frame extending substantially parallel to the lower surface of the platform (3) in the folded position (PRA).
  • This simple and reliable flip mount allows efficient retraction for loading into the van, while providing sufficient height when deployed to dock on the jambs.
  • the end of the frame is mounted freely pivotally on the platform (3), the gantry crane being equipped with a stand (92) with one end connected to said frame and one end received in a guide system ( 78,79) for providing a guide between the folded positions PRA and deployed PDE, said guide system being adapted so that the deployed position constitutes a single stable position of the gantry.
