This standard is under the jurisdiction of the China Elevator Association, and is jointly compiled by the Cold Chain Logistics Professional Committee of the China Federation of Logistics and Purchasing and domestic cold storage elevator manufacturers. It is applicable to traction and positive drive lifts with rated load of 500kg~5000kg and rated speed no more than 1m/s installed inside the cold storage, covering all scenarios of cold storage elevators including normal temperature vestibule type, low temperature vestibule type and full low temperature type. The core contents of the standard include: first, establishing the classification system of cold storage elevators, dividing them into four grades: high temperature cold storage type (0℃~-5℃), medium temperature cold storage type (-5℃~-25℃), low temperature cold storage type (-25℃~-45℃), and ultra-low temperature cold storage type (-45℃~-60℃) according to the applicable ambient temperature, and clarifying the design requirements and configuration standards corresponding to different temperature grades; second, refining the adaptive design specifications for low temperature environment, formulating special thermal insulation, anti-frost and anti-icing design requirements for elevator car, shaft, door system and guide rail system in view of the low temperature, high humidity and frosting characteristics of the cold storage, mandating that the cold storage elevator must be equipped with shaft heating, car thermal insulation and door system anti-icing devices to ensure the normal operation of the elevator in low temperature environment; third, improving the low temperature adaptation requirements of core components, formulating the performance requirements and selection specifications of traction machines, control cabinets, safety components, door machine systems and electrical components in low temperature environment, mandating that the core electrical components must meet the working requirements of -60℃ low temperature environment, the hydraulic system must adopt low temperature resistant hydraulic oil, and the lubrication system must adopt special low temperature grease; fourth, standardizing the safety protection and emergency function requirements, mandating that the cold storage elevator must be equipped with emergency heating, emergency lighting, emergency call and manual emergency release device in the car, and formulating special emergency rescue specifications for the scenario of people trapped in the low temperature car to ensure personnel safety; fifth, clarifying the installation and acceptance standards, formulating special construction specifications for shaft structure thermal insulation, equipment installation and commissioning, and low temperature environment performance test of cold storage elevators, clarifying the on-site acceptance items and qualification judgment criteria of cold storage elevators with different temperature grades, and incorporating low temperature operation performance into the special content of elevator supervision and inspection; sixth, refining the operation and maintenance and safety management requirements, formulating the cycle and project requirements for regular inspection and maintenance of cold storage elevators in view of the characteristics of low temperature, high load and high humidity use of cold storage elevators, clarifying the regular defrosting, anti-freezing and inspection requirements of the guide rail system, door system and electrical system, to ensure the long-term stable operation of the elevator. The implementation of this standard has comprehensively standardized the production and installation market of cold storage elevators in China, promoted the standardized and normalized development of cold storage elevator technology, adapted to the supporting elevator demand of the rapid development of China's cold chain logistics industry, and also provided standardized technical support for the export of China's cold storage elevator products to the global cold chain logistics market.
