For the first time, the transmission method of ball screw is adopted, which is more efficient and energy-saving than traditional trapezoidal screw. At the same time, it is equipped with a special screw anti-return mechanism to ensure the load stability and safety of the entire mechanism. With just one button, you can control the lifting and lowering of the outriggers.
