in accordance with the "special equipment safety law of the people's republic of china" and "special equipment safety supervision regulations", it is specified in the "special equipment catalog" issued by the general administration of quality supervision, inspection and quarantine approved by the state council, "elevator refers to power-driven, using rigid guide rails. running boxes or steps (steps) running along a fixed line, electromechanical equipment that lifts or transports people and goods in parallel, including manned (goods) elevators, escalators, moving walks, etc. it is not installed in public places and only for a single except for elevators used by households”. this is a broad definition of elevators given to clarify the scope of government supervision and management, and it is also a general term for equipment in this professional technical field. the "people (cargo) elevators" listed in the definition are elevators in a narrow sense from a professional and academic perspective, and are also typical and traditional vertical lift elevators; "escalators and moving walks" listed in the definition are elevator products, but also the real "electric staircase".
with the gradual expansion of urbanization, and the generalization of high-rise buildings in major and medium-sized cities in china, elevators have developed rapidly at an unprecedented rate. in recent years, the number of elevators has continued to grow, and the number of old elevators has increased year by year. at the same time, there are still a series of problems in the installation and maintenance of elevators in china. elevator related safety accidents occur from time to time, which has a negative social impact. the "opinions of the general office of the state council on strengthening elevator quality and safety work" was issued and implemented in 2018. it urges companies or institution using elevators to be responsible for elevator usage and management, strengthen elevator safety management, and keep daily inspection, maintenance supervision, and emergency response to ensure elevators that are safe to use. the quality inspection department has maintained a good situation in which the number of deaths in china's 10,000 elevator accidents has continued to decline in recent years through a series of measures such as improving the legal and standard system, strict market access, strengthening supervision and inspection and safety supervision, and carrying out hidden danger investigation and special rectification.
