in recent days, continuous high temperature, dryness, windlessness, and sultry … if you are in such an environment, you will definitely have a heat stroke for half an hour when you stand outdoors. do you know in the case of high temperature operation, the elevator will also strike due to “heat stroke”.

a few days ago, two elevators in hangzhou ’s qingcheng love community had “heatstroke”, resulting in people being trapped in such hot weather. it is understood that since the beginning of summer, as the temperature of the elevator machine room continues to be above 50 °, many elevators in this community have “struck” due to the extreme heat. at the same time, there were incidents of “strike trapped people” in elevators in other communities in hangzhou.

statistical data show that since the beginning of summer, hangzhou elevator failures have doubled. there are about 60 calls for help in this city every day. among them, 40% of elevator failures are caused by high temperatures. if the elevator is “heatstroke”, it may happen that the elevator door cannot be opened and closed normally, and suddenly stops running.

so how do we prevent heat stroke in the elevator? tips from sini mechanical & electrical: according to the relevant national standards, the temperature of the elevator machine room should be kept between 5 ℃ -40 ℃. if the temperature of the machine room exceeds 40 ℃, it is necessary to take cooling measures, such as installing air-conditioning in the machine room, adding ice cubes, perform ventilation work. in the face of the continuously appearing “barbecue mode”, the long-term high temperature of the elevator machine room may easily cause circuit failure, and the elevator will enter a thermal protection state and automatically stop operation. therefore, each contracted maintenance unit and property service unit should regularly check whether the cooling equipment is working properly, and regularly check and measure the operating conditions and temperature changes of the heating source (such as the inverter, braking resistor, and motor).

furthermore, if there are multiple elevators, they can be operated alternately to reduce the operating load of the elevator in high temperature elevators. when passengers ride the elevator, they encounter abnormal conditions or are trapped because of the elevator “strike”. they should contact the outside world as soon as possible. get in touch and call the property or elevator emergency rescue phone. don’t be upset by the high temperature and sweltering heat. you should relax and wait patiently for professional help.
