System for managing work modes of a mobile crane on a work site

A system for managing working modes of a mobile crane in a job site, the system comprising:

• a position sensor for the mobile crane in the job site,
• a position sensor for the hook of the mobile crane relative to a reference point of said mobile crane,
• a control circuitry configured to determine a working mode of the mobile crane from:
• the “displacement” mode corresponding to a displacement of the mobile crane in the job site,
• the “fixed work” mode corresponding to a situation in which the mobile crane is fixed in the job site and the position of its hook is variable,
• the control circuitry determining the working mode based at least on signals from the position sensor for the mobile crane and/or the position sensor for the hook and/or a state of deployment of shoes of the mobile crane;
• a communication device configured to communicate an indication of the working mode of the mobile crane to at least one other crane of the job site,
• wherein the control circuitry defines the working mode of the mobile crane by means of the position sensor for the mobile crane in the job site and/or the position sensor for the hook of the mobile crane relative to a reference point of said mobile crane.
