Abstract: A loading machine has working equipment which includes at least one arm, an actuator for displacing the arm, a working tool hingable with respect to the arm, a main kinematic chain forming together with the working tool part and the arm part a main deformable mechanism and a controllable tool actuator for deforming the main deformable mechanism to cause the tool to tilt. The machine also has a secondary kinematic chain forming together with the part of the arm, which is located in the area of articulation thereof on the frame, a deformable reference mechanism whose deformation directly corresponds to the inclination angle of the working tool, an angle sensor for measuring an angle displaying the deformation of the reference mechanism with respect to the frame, and a control device which is connected to the sensor and controls the feeding of the working tool actuator and/or the arm actuator.
