Work theory
Three spaces of top, middle and bottom will lift together. Usually, two spaces of middle and bottom are put in the pit. The top space is at the same level as the ground. It may be parked directly. When it is lifted up, the middle and bottom spaces may be parked with cars.

Characteristics of equipment
1. Save land area and take full use of the underground space.
2. Achieve multiple parallel layout, increase the number of parking.
3. The middle and bottom spaces have functions of dustproof, rainproof and anti-theft.
4. Simple and reliable, easy to operate.
