Building Construction (Conveying Systems - EscALATors)

An escalator is a power-driven stairway consisting of steps attached to a continuously circulating belt. It is used for moving passengers up and down between floors.

A moving sidewalk is a power-driven surface that is continuously moving, similar to a conveyor belt. It is used for carrying pedestrians horizontally or along low inclines. This is different from a stair lift, which is specifically designed to carry individuals up and down stairs. An inclined lift is also used for transporting people vertically, but it operates on an incline rather than a horizontal surface. An escalator is another type of continuously moving surface, but it is specifically designed for transporting people between different floors in a building. Therefore, the correct answer is moving sidewalk.

The angle of inclination of an escalator is 30 degrees.

A truss is a structural framework made of welded steel that is used to support and strengthen various types of structures. In the context of an escalator installation, a truss would be the welded steel frame that supports and holds the moving stairway equipment in place. This frame provides stability and ensures that the escalator functions safely and efficiently.

An inclined lift is a chair or platform mounted on a steel guide rail and driven by an electric motor, used for raising or lowering a person or goods along a stairway. It is different from an escalator or a moving sidewalk as it specifically refers to a lift that moves along an inclined path.

The correct answer is "people mover." A people mover refers to any form of mass transit used for shuttling people across airports or in congested urban areas. It can include various modes of transportation such as moving sidewalks or automated driverless vehicles.

The correct answer is inclined moving sidewalk. This is because an inclined moving sidewalk, also known as a travelator or movator, is a type of moving ramp that is commonly used in airports and supermarkets to transport people from one floor to another. It is a sloped conveyor belt that moves people along with it, allowing for easy and convenient transportation between different levels.

A newel is a horizontal section of railing located at the upper and lower end of an escalator. It serves as a support and handrail for individuals using the escalator, providing stability and safety. The newel is typically made of a sturdy material such as metal or wood and is designed to withstand the weight and pressure exerted by people leaning on it while using the escalator. Its purpose is to ensure that users can safely ascend or descend the escalator without any risk of falling or losing balance.

A stair lift is another name for an inclined lift. This type of lift is designed to transport individuals up and down a staircase, providing a safe and convenient solution for those with mobility issues. The inclined lift is specifically designed to fit onto the staircase, allowing users to easily access different levels of a building without the need for a traditional elevator. The term "stair lift" is commonly used to describe this type of inclined lift.

The correct answer is 2 ft x 2.6 ft. This means that the size of the dumbwaiter car is 2 feet in width and 2.6 feet in height.

The correct answer is skirt panel safety switch, skirt panel switch, and skirt panel safety. These options refer to safety mechanisms in an escalator's skirt panel. When something gets stuck between the step and the skirt panel, these safety switches are designed to detect the obstruction and automatically stop the escalator to prevent any accidents or injuries.

In cases of emergency, the escalator can be stopped by pushing the emergency stop switch. This switch is specifically designed to halt the escalator immediately in order to ensure the safety of individuals in emergency situations. It provides a quick and accessible solution to stop the escalator when needed, preventing any further potential harm or accidents.

The correct answer is "step yellow frame" because it is a sign indicating the safe location where the passenger should stand. This suggests that there is a yellow frame on the step that serves as a guide for passengers to stand on, ensuring their safety while boarding or exiting a vehicle.

The correct answer is "tracks." The explanation for this answer is that steel angles are attached to the truss, and these angles serve as guides for the step rollers. These guides are commonly referred to as tracks, as they provide a designated path for the step rollers to move along.
