It belongs to a storage facility, which is specially designed for automatic parking and scientific storage of various types of vehicles. It is composed of six major parts: steel frame, vehicle carrying plate, lifting system, traverse system, safety device, and electrical control system. At present, it has been developed and popularized in cities with a relatively high population density, and has become increasingly mature.

The three-dimensional garage is combined by a complete system. Each system as an integral part plays an important role in the safety and performance of the entire system. The following is an analysis of the purpose of each branch by a three-dimensional garage expert:

1. Power supply system phase failure, wrong phase protection device: phase sequence protection relay.

2. Run with fault. The operation of the hoisting system when the speed limiter fails, or the motor is out of phase or out of phase is called faulty operation.

3. Bottom bumper: buffer.

4. Speed ​​protection system: speed limiter, safety gear.

5. Runaway overspeed. During the lifting process, once the brake fails, or the gear teeth, shaft, keys, and pins of the reducer are broken, or the traction rope is severely slipped or broken, the lift car will be out of control and the running speed will exceed the limit speed.

6. The terminal is offside. When the leveling control circuit fails, the car moves to the top or bottom floor, it will exceed the normal position, or continue to run, causing the top or squat.

7. Suddenly stopped. Due to the failure of the control system or the power failure of the power grid, the hoisting system will suddenly stop running. Suddenly stopped. Due to the failure of the control system or the power failure of the power grid, the hoisting system will suddenly stop running.
