Abstract: An industrial device including a portable tool and a support for this tool. The tool is provided with a motor driving a mechanism in rotation, an electrical energy store to power the tool during operation and a controller to control the motor. The support includes a line, one extremity of which is affixed to the tool, a receiving element defining a location for the grasping of the tool and a winding apparatus of said line exerting a vertical tension to the tool so as to lighten its weight when it is no longer at its grasping location. The industrial device further includes a transmission of an electrical energy to charge the energy store when the tool is positioned in the receiving element. The tool is light weight tool while at the same time highly maneuverable in charging supercapacitors or a battery only when the tool is on the support.
