1. What is the primary function of an escalator handrail?
a) Support the escalator steps
b) Balance the step chain
c) Guide passengers and provide safety
d) Drive the motor
c) Guide passengers and provide safety
The handrail helps passengers maintain balance and prevents
falls.
2. Which component connects the escalator steps to the drive
system?
a) Handrail
b) Step chain
c) Comb plate
d) Balustrade
b) Step chain
The step chain links the steps and transmits motion from the
motor to the steps.
3. What is the purpose of the comb plate on an escalator?
a) Protect the step chain
b) Engage and disengage the handrail
c) Minimize the gap between steps and landing
d) Support the drive motor
, c) Minimize the gap between steps and landing
The comb plate reduces the risk of objects or feet being trapped at
the top or bottom of the escalator.
4. Which safety device stops the escalator if an object is detected at
the skirt panel?
a) Handrail switch
b) Skirt switch
c) Step chain tensioner
d) Brake system
b) Skirt switch
Skirt switches detect entrapment between the steps and side
panels, stopping the escalator to prevent injury.
5. What type of brake is commonly used in escalator drive systems?
a) Hydraulic brake
b) Spring-applied, electrically-released brake
c) Friction disk brake
d) Air-actuated brake
b) Spring-applied, electrically-released brake
