The invention discloses a safe, high-efficiency and energy-saving elevator. A constraint rail is increased on an arc operation section, multiple places are constrained, the elevator car refers to a composite elevator car with double nested boxes, the inner elevator car can move up and down in the outer elevator car, a cable chain wheel system comprises a bearing chain wheel and a matched chain cable, the chain cable refers to a rope formed by combining a chain and a cable into a whole, the 100-percent security constraint and security assurance of the total operation tracks can be realized, and the height position of the inner elevator car can be finely adjusted, so that the inner bottom plane of the inner elevator car is accurately flush with the ground level of the building, the personnel access and cargo handling can be conveniently realized, the advantages of the chain and cable are maintained, the defects of the chain and cables are overcome, the operation is stable and noise-free, buffer and vibration absorption can be realized, the defects of the existing technology are overcome, and the security assurance, stop position accuracy and operating stability of the multi-elevator car high-efficiency and energy-saving elevator are greatly improved.
