Elevator Safety Features

Elevator is a combination of software and hardware, means all movable parts in Elevator is operate by the microcontroller, if any type of technical problems will generate than we should have many safety features for any type of decontrolling. That's why in elevator many safety features attach for controlling the hardware and software.

In elevator mostly following safety features include:-

Safety in case of over travel:

Tree phase electric power is disconnected from control panel and motor, the moment elevator car moves beyond the limit of top and bottom terminal floors causing immediate application of the brake to bring the elevator to halt.

Safety in case of rope breakage:

In the elevator of breakage of ropes, elevator speed exceeds the rated speed in the downward direction due to gravitational acceleration. The over speed governor activates the clutch mechanism thereby switching off main controls and jamming the elevator car safety on guide rails.

Auto Rescue Device:

In the event of power cut off, the elevator will continue to operate till the nearest floor and open the doors to let passengers out safety.

Infrared Light curtain:

Full height infra red curtain with multiple cross-crossing light beams detect the smallest obstruction in door path and stop doors from closing.

Car Fan Automatic Sleep:

Car fan automatically stops when there are no registered floor calls resulting into saving in power and enhancing its life.

Voice annunciator with music:
