VEHICLE-MOUNTED CAMERA CRANE

A vehicle-mounted rocker arm without counterweight, includes a heading shaft, a pitching shaft part, an arm body, a damping arm, and a housing. The pitching shaft part includes a main structure frame, a rocker arm, a servo electric cylinder, and a gas spring. The gas spring can balance the weight loaded by the arm body so that the force exerted by the servo electric cylinder during stretching and contracting is balanced, so as to achieve the effect of balancing the longitudinal center of gravity of the arm body without using a counterweight. The vehicle-mounted rocker arm without counterweight is further characterized in that pitching shaft part and the rotating shaft are independent modules, and can be dismounted and installed separately. The vehicle-mounted rocker arm without counterweight is further characterized in that the arm body part has a truss type quick butting structure.
