The power plug of the cable and the vehicle plug are randomly placed on the cement ground, and two specifications of 5000 ± 250) N and (11000 ± 550) N are pressed over the power plug or vehicle plug at a speed of (8 ± 2) km/h (tire inflation pressure 220 ± 10 kPa) to test the ability of the power plug or vehicle plug to withstand rolling.

      Place the power plug and vehicle plug with the manufacturer's recommended cable randomly on the cement floor, and apply a standard pressure of 5000 ± 250N at a speed of (8 ± 2) km/h to the power plug or vehicle plug (tire inflation pressure of 220 ± 10 kPa) to test the ability of the power plug or vehicle plug to withstand rolling. The experimental device mainly consists of two parts: electrical and mechanical. The mechanical part mainly consists of the power part, transmission part, slide table, cylinder, etc. The motor adopts servo motor. The electrical control system is composed of programmable controllers and touch screens, which facilitate users to set various test parameters and enable remote control. This testing device can meet the requirements of customer tire crushing charger testing according to the testing standards, and is an ideal testing device for professional testing institutions, product manufacturers, and quality inspection departments at all levels.
