In recent years, there have been raised racing events for kart cars, college formula cars, and other small racing cars that are suitable for individuals, families, or small teams to participate. The mass of the small racing car is generally below 300kg, the length is not more than 3m, and the width and the height are not more than 1.5 m. In the field of racing, it is often necessary to suspend the vehicle for maintenance and adjustment, for example: changing tires, adjusting inclination angles, toe angles, chassis heights, or performing maintenance. Due to the need for racing, the commissioning of a race car must be as rapid as possible. The weight of the racing car cannot be lifted independently by an adult man, and the number of the racing teams of the small racing car is limited, so that the aim of quickly lifting the racing car from the ground by a certain height by using a lifting tool is fulfilled.

Currently, the most common tools in the field of vehicle maintenance and adjustment are hydraulic platforms or small hydraulic jacks, for example, CN212799421U an outdoor maintenance hydraulic lifting device for locomotives and CN212403350U vehicle maintenance lifting machine, both use hydraulic structures for vehicle lifting.
