There are several types of escalators, each designed for specific environments and applications. Here are some common types:
Commercial escalator
This is a type of moving stairway commonly found in shopping malls, airports, and other places where large numbers of people need to be moved between different levels. It is divided into two types:
Heavy-duty escalators are designed to carry a high capacity of passengers with durability and reliability. They are ideal for environments such as high-traffic retail stores, transportation hubs, and public event spaces.
Standard commercial escalators are suitable for typical commercial applications where passenger traffic is moderate. They are ideal for office buildings, hospitals, and lower-traffic retail stores.
Industrial escalators
These escalators are built to endure harsh conditions, heavy loads, and specialized applications. They are usually used in factories, warehouses, and industrial plants. They have robust construction, larger load capacities, and increased durability compared to commercial escalators.
Spiral escalators
These escalators move in a circular motion as they go up or down. They are used in places where a straight escalator would not work well, like in the middle of a big room. They take up more space than regular escalators but look cool because of their curved shape.
Outdoor escalators
These escalators are placed outside in open-air areas, like on the sides of buildings that are tall. They are made to handle weather changes, such as rain, snow, and wind. These escalators have covers to protect people using them from the weather.
Escalator lift
This machine combines features of an escalator and a lift (also called an elevator). It can carry people or things up and down quickly and smoothly, even between floors that are not level with each other. This lift is suitable for moving people with disabilities or large objects between different levels.
All the functions listed below are common on most moving staircases:
Power-driven Stairs
The primary function of an escalator is to transport people between different floors. The escalator is a better choice than a flight of stairs, as it moves continuously and only requires one person to monitor its operation.
Handrails
These are continuous loops that passengers grip while on the moving stairs. Handrails are usually installed on both sides of the escalator. They move at the same speed as the steps, ensuring passenger safety and comfort.
Comb Plates
These plates are located at the top and bottom of the escalator. They look like combs and guide passengers as they enter and exit. The combs have anti-slip features to prevent accidents.
Skirts
These are panels that cover the sides of the escalator. They protect people from getting stuck in the gap between the steps and the escalator's outer edges. Skirts also help prevent debris from entering the escalator's inner parts.
Emergency Stop Button
These buttons are usually located near the handrails. If passengers notice any issues while using the escalator, they can press the emergency stop button to halt the operation. This feature is important for preventing accidents and injuries.
Control Panel
This is the brain of the escalator. It controls its operation, including the speed of the steps and handrails. The control panel ensures the different components of the escalator function in unison.
Safety Sensors
These components monitor the escalator for any potential hazards. For example, they can detect if a passenger's clothing is caught in the comb plate. If they sense any danger, they will activate the emergency stop immediately.
Handrail Drive System
This system drives the handrails and consists of a motor, pulleys, and belts. It ensures the handrails move smoothly and at the same speed as the steps.
Lighting
Most escalators are fitted with lights. These illuminate the steps, handrails, and comb plates to ensure passengers see them, especially in low-light environments. Escalator lights enhance safety and improve the aesthetic appeal of the escalator.
Step Chain
The step chain connects the different components of the escalator, such as the driving motor and steps. It transfers power from the motor to the steps, ensuring smooth and continuous movement.
The global market for escalators is on the rise. The compound annual growth rate is forecasted to be around 6.5% from 2023 to 2030. This is not surprising since escalators are widely used in buildings and structures. They are a necessity in most modern infrastructures.
There are many different usage scenarios for escalators. Here are some of them:
The factors below can help buyers decide which type of escalator to purchase for their business and what price point makes sense for their budget.
Safety features
All escalators should be equipped with safety features such as emergency stop buttons, handrails, and anti-slip steps. The emergency stop button allows users to halt the escalator in an emergency. Handrails provide support to people using the escalator. Anti-slip steps prevent passengers from slipping while on the escalator. These safety features are important and should be part of any escalator purchase.
Capacity and traffic flow
Consider the number of people who will use the escalator each day. High-traffic locations like airports and malls may require escalators that can transport a large number of people quickly. These types of escalators are available for purchase at different price points. Low-traffic areas can use escalators that accommodate fewer passengers at a time. Traffic flow and capacity should be considered when buying an escalator.
Durability and reliability
It is important to buy an escalator that can withstand regular use without breaking down. Look for an escalator that is built with strong materials like stainless steel and high-quality plastic. Read reviews or talk to other customers to find out if the escalator brand has a reputation for reliability. Choosing a durable and reliable escalator will prevent future replacement and extra costs.
Installation and maintenance
Business owners should think about the cost of installing and maintaining the escalator over time. Some escalators may be more expensive to keep up than others, so it's important to look at the long-term budget. Also, consider the location of the escalator and how it will be installed. Buying an escalator that is easy to set up and maintain can save time and money in the future.
Customization
Some escalators can be customized to fit the needs of a certain business. This includes changing the size, slope, or materials used to make the escalator. If a business has special requirements, talk to an escalator expert about the choices available for customization. Customized escalators are available at various price points depending on the adjustments made.
Q1: What are the major components of an escalator?
A1: The major components of an escalator include the drive machine, handrail, comb plate, step chain, and riser. Other components are escalator steps, moving walkway, motor, transmission, drive, and track system.
Q2: What is a moving walkway?
A2: A moving walkway is a type of escalator that moves people and passengers over short distances. It is also known as a moving sidewalk or travelator. There are two main types of moving walkways: inclined and horizontal.
Q3: What is the maximum height of an escalator?
A3: The maximum height of an escalator differs based on the type. For example, the maximum height of a modular escalator is 59 feet or 18 meters. On the other hand, the maximum height of a rack-driven escalator is 98 feet or 30 meters.
Q4: What is escalator inclination?
A4: The inclination of an escalator refers to the angle between the escalator and the ground. The inclination usually ranges between 30 and 35 degrees.
Q5: How does the escalator safety brake work?
A5: The safety brake will engage automatically if the escalator experiences rapid acceleration or deceleration. This will bring the escalator to a smooth and safe stop. It is designed to prevent accidents and ensure passenger safety.
