  • a work platform comprises a substantially horizontal surface that an operator may stand on, and may or may not include additional components such as a guard rail and/or controls for operating the work platform.
  • the barrier may be configured to couple to the work platform such that the barrier projects from the work platform at an angle of between 20 and 70 degrees to horizontal, in particular between 30 and 60 degrees, more particularly between 40 and 50 degrees, for example approximately 30, 45 and/or 60 degrees.

Abstract

L'invention concerne des plates-formes de travail d'élévation mobiles (MEWP) qui sont couramment utilisées dans des activités de construction et de maintenance. Dans de nombreux environnements d'exploitation, les outils doivent être fixés à la plate-forme de travail par des cordons ou des dispositifs similaires. Cependant, les petits objets (comme les écrous et les boulons) sont très difficiles (voire impossibles) à fixer de cette manière. Selon un premier aspect de la présente invention, l'invention concerne un dispositif de sécurité de plate-forme de travail, comprenant: une barrière (11) configurée pour s'accoupler à une plate-forme de travail de telle sorte que la barrière (11) fait saillie à partir de la plate-forme de travail au moins horizontalement. De cette manière, des articles lâchés sur le côté de la plate-forme de travail peuvent être rattrapés par la barrière.
