Definitions

  • the present invention relates to a control system for a hydraulic crane with articulated arms.
  • the present invention proposes to provide a system for driving and piloting a hydraulic crane with articulated arms, or any other similar system, allowing simpler and more intuitive handling while providing great precision in controlling the trajectory. articulated arms.
  • the invention relates to a control and piloting system for a hydraulic crane with articulated arms, characterized in that it consists of a lever of the "stick" type with three control axes: - The rotation of the lever on itself controlling the rotation of the crane relative to its support, in particular on its turret; - the other two axes, orthogonal, used to obtain the horizontal and vertical components of the desired speed of the load.
  • the system according to the invention is characterized in that it comprises: - a set of sensors, measuring at all times the quantity of hydraulic fluid delivered to each thrust cylinder and therefore the geometric position of each articulated arm (in accordance with the device described in the patent application filed on the same day as this application by the same holder for a "device for measuring the geometric position of the articulated arms of a mobile crane"); - a control box, provided with said lever or “stick”, on which the user displays the desired speed vector for the load in a coordinate system in Cartesian coordinates; - a computer to determine the hydraulic fluid flow rates to supply the cylinders to obtain the desired path and - proportional electrically controlled hydraulic distributors to convert the electrical control voltages from the computer into flows delivered to the cylinders.
  • the computer can also prohibit certain movements requested by the user when these risk causing the safety limits of the crane to be exceeded or overturning the carrier vehicle.
