Definitions

  • the invention relates to a system for assisting in the assessment and management of a danger on a lifting platform.
  • Elevating platforms generally comprise a lower part provided with ground connection members, a platform which rises in height and on which operators take place to carry out certain work, and an lifting structure between the lower part and the platform.
  • Some lifting platforms are adapted, by virtue of the deployment possibilities of their lifting structure, to perform work at great heights and offset from the platform with respect to the lower part, which can result, for example when the platform is located above the roof of a building, the non-visibility of the platform and its occupants by the personnel present on the ground around the lower part. In the event of an emergency situation concerning the operators of the platform, the distance and the non-visibility of the operators run the risk of them not being able to report emergency situations.
  • the invention more particularly intends to remedy by proposing a new system for assisting in the assessment and management of a danger, making it possible to react quickly to an emergency situation occurring on the platform. of the lifting platform.
