Lift Technician Interview Questions and Answers for Freshers

A safety rope is a device used in elevators to prevent the car from falling in the event of a malfunction.

• A safety rope is typically made of steel and is attached to the elevator car and the counterweight.

• In the event of a malfunction, the safety rope will engage and prevent the elevator car from falling.

• The safety rope is designed to withstand the weight of the elevator car and provide a reliable backup in case of an emergency.

• Regular inspections and maintenance of the safet...read more

A diode is an electronic component that allows current to flow in only one direction.

• A diode has two terminals: an anode and a cathode.

• It acts as a one-way valve for electric current.

• When the voltage across the diode is positive, it allows current to flow.

• When the voltage across the diode is negative, it blocks the current.

• Diodes are commonly used in rectifier circuits, voltage regulators, and signal demodulation.

ARDA stands for Automatic Rescue Device for Elevators. It is a safety feature that helps evacuate passengers in case of power failure or elevator malfunction.

• ARDA is an emergency system installed in elevators.

• It is designed to automatically lower the elevator to the nearest floor and open the doors in case of power outage or other emergencies.

• ARDA ensures the safe evacuation of passengers by providing a backup power source and controlling the elevator's movement.

• It is a cruci...read more

A lift is a vertical transportation device used to move people or goods between floors or levels of a building.

• Lifts are also known as elevators.

• They are powered by electric motors and use cables, pulleys, and counterweights to move up and down.

• Lifts can be found in various types of buildings such as offices, hospitals, shopping malls, and residential buildings.

• They are designed to carry a certain weight limit and have safety features such as emergency brakes and sensors to p...read more

A resistor is an electrical component that limits or controls the flow of electric current in a circuit.

• Resistors are used to control the amount of current flowing through a circuit.

• They are passive components that dissipate energy in the form of heat.

• Resistors are measured in ohms (Ω) and have color-coded bands to indicate their resistance value.

• They can be fixed resistors with a specific resistance value or variable resistors that can be adjusted.

• Resistors are commonly used...read more
