● The equipment machinery mainly adopts imported originals to complete the nut tightening, which is precise and fast, stable in performance, and reduces artificial strength;

● Using the servo motor, the torque can be set and the operation is faster. The torque of the connector can be set directly through the touch screen menu or the position of the connector can be directly adjusted to complete the required distance of the nut;

● The equipment machinery completes the screwing of the positive and negative connectors at a time, and the efficiency is high.
