✍️ Sample CET Questions & Answers
1. Which type of motor is commonly used in modern traction elevator systems?
AC gearless permanent magnet motors are widely used for their energy efficiency and smooth operation.
2. What issue is indicated by frequent elevator leveling problems?
Frequent leveling issues can signal faulty sensors or brake malfunctions affecting stop accuracy.
3. What is the function of the oil buffer in the elevator pit?
Oil buffers absorb and dissipate the kinetic energy of an elevator car or counterweight running into them, preventing sudden impact.
4. What is the purpose of 'compensating ropes' or 'compensating chains' in a tall-rise traction elevator?
Compensating ropes or chains loop under the car and counterweight to compensate for the changing weight of hoist ropes as the car moves up and down in high-rise applications.
5. What is the purpose of 'rope clips' (Crosby clips) when used on elevator hoist rope installations?
Rope clips are a temporary field tool used only during rope installation and adjustment, never as permanent load-bearing hoist rope terminations on elevators.
6. What is the purpose of the counterweight guide rails?
Counterweight guide rails constrain the counterweight to a precise vertical path, preventing lateral movement that could cause contact with hoistway walls or the car.
