Definitions

  • the invention relates to the field of workshop or site equipment. More particularly, the invention relates to a portable workbench.
  • An electrical technician (or other), as part of a maintenance or troubleshooting on site, generally needs to move with documents, a laptop computer as well as tools and equipment. It also needs on-site provisions allowing its effective and safe installation for the duration of the site; its installation must allow it to intervene between a few hours to several days depending on the nature of its intervention. However, an industrial production unit generally does not offer good provisions for an effective and safe installation of the intervention technician.
