It is the most terrifying and traumatizing experience riding inside an elevator when an earthquake occur. There is possibility one could be entrapped inside the elevator in the event and thereafter. The worst case scenario is – the car and counter weight frame can be derailed allowing both mechanical parts to sway freely. Thus, increasing the risk of collision of both inside the shaft if the elevator keeps running that may eventually turn out to fatalities and further equipment damages.
The ASME code A17.1-2016 also known as ” Safety Code for Elevators and Escalators” requires all lift to have a feature for emergency Earthquake Operation (EQO). Wherein, the lift at the detection of a moderate seismic event will directly approach, stop and open its door at the nearest landing allowing passenger to exit the car as soon as possible.
This Earthquake Operation is a built-in feature for all ASME A17.1 compliant elevators. However, the seismic sensing device (SEISMIC SWITCH) is not included for most installation. So, for elevators which do not have yet a seismic switch, the Earthquake Operation feature cannot be activated in times of tremors.
FRB Elektromek Automation Services offers a reliable SEISMIC SWITCH calibrated to detect both low and extra low earthquakes, quality assured and tested because it is Japan made.
