2.Are our elevators safe? -About the door
1). The 1st line protection - the light curtain will automatically reopen the door when it senses an obstacle;
2). The 2nd line protection - the door inverter will give signal to reopen the door when the obstacle reaches 150N to prevent people from being pinched.
3. Are our elevators safe? -How to prevent falling and hitting the top
1). All our safety components are with CE and EAC certification;
2). When the elevator falls faster than 1.15 times the rated speed, the speed governor and tension device will activate the lifting rod of the safety gear, which can stop the further fall by braking the guide rail;
3). When the upward speed exceeds 1.15 times the rated speed, the control cabinet will send a signal to the traction machine, and the traction machine will brake, so that the traction machine will stop going up.
