Abstract
Elevator is a transport device that is used to move people or goods in vertical direction. In this paper programmable logic based elevator control system is constructed to simulate as an actual lift in real life. Here, a new method for traction based elevator system is introduced which doesn’t need a counterweight. By this method friction along the traction sheave of the elevator can be improved. To reduce friction along the rails bearings are used in the hoisting mechanism. Servo motor (Mitsubishi’s HJ-KS43J) is used as the prime mover for its accurate positioning capability. SIEMENS S7 200 SMART PLC was used for controlling the entire system. PLC is interfaced with hooters, floor switches, indicators and sensors for effective functioning of the elevator system.
