在地震來(lái)襲前，電梯地震感知器可以檢測(cè)到地震波，通過(guò)電梯控制系統(tǒng)使電梯盡快在最近的樓層平層開(kāi)門(mén)，使乘客及時(shí)撤離。這樣的電梯地震預(yù)警目前在四川少數(shù)電梯上得到應(yīng)用。

在近年歷次地震中，由于地震時(shí)電梯仍在運(yùn)行，導(dǎo)致電梯破壞、乘客被困等情況，對(duì)人員及時(shí)撤離造成影響。汶川地震六個(gè)重災(zāi)區(qū)的近5萬(wàn)臺(tái)電梯中就有2萬(wàn)多臺(tái)受損，近千臺(tái)電梯報(bào)廢或需重大維修；2014年康定地震中，發(fā)生乘客被困電梯2個(gè)小時(shí)的情況。

地震感知器有機(jī)械式和電子式兩種

在地震中一般電梯對(duì)重會(huì)從導(dǎo)軌中脫離、轎廂損壞、電機(jī)移動(dòng)、導(dǎo)靴損壞等，導(dǎo)致電梯困人或傷人。

在日本、美國(guó)、歐洲，地震多發(fā)國(guó)家或地區(qū)，電梯中必須安裝地震感知器，提前感知地震波，在大地震來(lái)臨前，控制電梯就近平層，避免電梯懸停在樓層之間，持續(xù)敞開(kāi)電梯門(mén)，保障乘客及時(shí)安全撤離。

我國(guó)電梯標(biāo)準(zhǔn)委員會(huì)也在地震中的電梯標(biāo)準(zhǔn)做出了技術(shù)指導(dǎo)和相應(yīng)的規(guī)定，但由于價(jià)格競(jìng)爭(zhēng)等因素，地震帶上的電梯也未能普及，人員財(cái)產(chǎn)的保障相對(duì)缺乏，有待進(jìn)一步推廣應(yīng)用。

新電梯中國(guó)編輯提請(qǐng)廣大電梯采購(gòu)者：自然無(wú)情人有情，預(yù)防災(zāi)情需提早，勿使價(jià)格成勒拌，勿以輕心丟性命。

Seismic Sensor in Elevator Should be Widely Applied in Earthquake Zone

Normal elevators are to suffer problems as derailment, car damage, motor movement, guide shoe damage, etc. in earthquakes which may cause passengers trapped or injured.

Seismic sensors are required to apply to elevators in earthquake-prone countries and regions like Japan, America and the European area, so that the elevator can sense seismic wave in advance, drive the elevator car to the nearest floor, and open the doors to let passengers evacuate safely.

Chinese Elevator Standard Committee has also released some technology guidance and relevant regulations in case of elevators in earthquakes, while unfortunately, such sensors are not popular in seismic zone and residents’ life and property safe are under little security, due to price competition and more reasons.Such circumstances calls for immediate solution and seismic sensors should be widely applied especially in seismic zone.

CNLift 360 admonishes all friends that as the unexpected always happens,to minimum the loss in disasters, we should take measures promptly and never let high cost block your escape corridor.
