Compared with the underground garage, the safety of the person and vehicle can be guaranteed more effectively. The person is not allowed to stop in the garage or in the car, and the whole equipment controlled by the electronics will not work. It should be said that the management of mechanical garage can be done completely. The use of mechanical parking in underground garage can also relieve heating and ventilating facilities. Therefore, the power consumption in operation is much lower than that in underground garage managed by workers. Mechanical garage generally does not make complete sets of systems, but is built by single container. This can give full play to the advantages of less land and can be divided into zero, and a mechanical parking building can be set up at random in every group of groups or downstairs in the residential area. This provides a convenient condition for solving the problem of parking at present in the garage shortage area.
