The invention provides a chain drive type three-dimensional parking apparatus. The chain drive type three-dimensional parking apparatus includes a steel structure main body frame, loading platforms, chain suspension devices and driving devices; each chain suspension device comprises two chain suspension assemblies which are symmetrically arranged at two sides of the loading platform; each chain suspension assembly includes a front suspension component, a front chain component, a front sprocket, a rear suspension component, a rear chain, a rear sprocket, double rows of drive sprockets, a pulley block, an auxiliary sprocket and a steel wire rope, wherein the front suspension component and the rear suspension component are fixed on suspension positions of the steel structure main body frame, the front sprocket is fixed below the front suspension component, the rear sprocket is fixed below the rear suspension component, and the front sprocket, the pulley block, the double rows of drive sprockets, the auxiliary sprocket and the rear sprocket are sequentially fixed at two sides of a corresponding loading platform. Based on combination and cooperation of the chains and the steel wire ropes, the chain drive type three-dimensional parking apparatus has the advantages of simplicity, stable operation, low cost and high safety performance. With the chain drive type three-dimensional parking apparatus adopted, vehicles with larger sizes can be parked.
