Parking system for cars has double level stack with lower level in form of lift set in ground and moved vertically by controlled electrical or hydraulic actuators

摘要

The car parking system has a series of holes in the ground that are lined with concrete and each sized to receive a car (3). The cars sit on a platform lift (5) that can be moved vertically by controlled actuators (6), which may use either electrical or hydraulic power. A second car is parked above and sits on the roof platform. The lift moves between lower and upper positions to park and retrieve a car.
