Core contents of the standard: First, low temperature environment design requirements, clarifying that elevators in severe cold areas must adapt to the extreme ambient temperature of -40℃~60℃. Elevator machine rooms and control cabinets must be equipped with electric heat tracing + temperature control system to ensure that the machine room temperature is always maintained between 5℃~40℃. The shaft must be equipped with cold and thermal insulation layer, and the landing door must be equipped with cold proof sealing strip to prevent cold air from entering the shaft; Second, component cold resistance requirements, elevator electrical components, hydraulic systems, lubrication systems, and safety devices must be selected from low temperature resistant models, which can start normally and operate stably in -40℃ low temperature environment. Elevator steel wire ropes and guide rails must be selected from low temperature resistant and corrosion resistant materials to prevent low temperature brittle fracture and corrosion; Third, installation and construction specification, clarifying the temperature requirements, cold protection measures and acceptance standards for elevator winter installation and construction in severe cold areas. When the ambient temperature is lower than -10℃, elevator electrical installation and commissioning operations shall not be carried out. After installation, low temperature environment operation test must be carried out, and it can be put into use only after passing the test; Fourth, winter maintenance requirements, clarifying the cycle, items and standards of elevator winter maintenance in severe cold areas. The winter maintenance cycle is shortened from 2 months to 1 month, focusing on checking the cold and thermal insulation system, low temperature operation performance, lubrication system, and emergency leveling device, and conducting a low temperature emergency operation test every month; Fifth, emergency management requirements, elevators in severe cold areas must be equipped with dual power supply + emergency energy storage system, which can ensure at least 20 round trips of the elevator after power failure. At the same time, formulate emergency disposal plans for low temperature failures in winter, equip emergency rescue equipment and cold protection materials, and the response time for trapped rescue shall not exceed 30 minutes.
