What is an Escalator and How Much Does It Cost？

What is an Escalator?

An escalator, also known as an electric escalator or moving staircase, is a transportation device that conveys pedestrians using a continuous belt system. Typically installed at an incline, escalators transport individuals from one end to the other effortlessly. Passengers stand on the moving steps at the entrance of the escalator, and the steps remain level throughout the journey. For passenger safety and support, escalators are equipped with handrails on both sides that move in sync with the steps, allowing passengers to hold onto them while riding.

How Does an Escalator Work?

An escalator is a mechanical device used to transport people between different floors of a building. It consists of a series of steps or treads that move in a continuous loop, allowing passengers to step on or off as needed. Let’s delve into the workings of an escalator:

Step Chain: The steps are linked together by a looped metal chain that forms an unending belt. This chain is driven by an electric motor located at the top or bottom of the escalator.

Motor and Drive System: The motor powers the escalator and is typically an electric motor located in a machine room. It provides the necessary energy to move the steps in a continuous motion. The motor’s rotational motion is transmitted to the step chain through a series of gears and pulleys.

Handrail Drive System: In addition to the steps, escalators also feature handrails on both sides. The handrails move at the same speed as the steps to provide support and stability for passengers. The handrail drive system consists of a separate motor and drive mechanism specifically designed to move the handrails.

Tracks and Guides: The steps and handrails run on tracks and guides to ensure smooth and precise movement. These tracks and guides are typically made of metal and are designed to keep the steps and handrails in their proper positions as they travel along the escalator.

Balustrade: The balustrade is the structure that encloses the sides of the escalator. It provides a protective barrier for passengers and prevents them from falling off the sides. The balustrade often incorporates the handrail system.

Safety Features: Escalators are equipped with various safety features to ensure passenger safety. These include comb plates at the entrance and exit points, which help prevent tripping hazards, and skirt brushes that minimize the risk of entrapment between the steps and the balustrade.

Sensors and Controls: Escalators have sensors and control systems that monitor their operation and detect any anomalies or obstructions. For example, if an object gets caught in the escalator, sensors will detect the issue and trigger an emergency stop to prevent accidents.

When the escalator is powered on, the steps and handrails move in a synchronized manner. As one end of the chain moves over the top of the escalator, the steps are lifted and positioned horizontally at the entrance. They then move in a diagonal path, transporting passengers smoothly between different levels of a building. Finally, the steps reach the bottom of the escalator, dip down, and loop back to the top to repeat the cycle.
It’s worth noting that while the basic principles of escalator operation remain the same, there may be variations in design and configuration depending on the manufacturer and specific installation requirements.

How Much Does an Escalator Cost?

The cost of an escalator can vary significantly depending on various factors, such as its length, rise height, running speed, step width, finishes, etc. The price range for an escalator falls between $15,000 and $25,000, luxury or high-end models might cost even more. If installation is included, the cost of an escalator can range from $20,000 to $30,000.

For a precise and up-to-date estimate, it is recommended to consult escalator manufacturers or suppliers, as prices can change over time and may differ based on specific project needs.

Factors Influencing Escalator Price

1) Inclination Angles
Inclination angles for commercial escalators are available in options of 30 and 35 degrees. This angle strikes a balance between providing a smooth and comfortable ride for users and maintaining efficient operation.

Airports, train stations, and subway stations often utilize heavy-duty escalators due to their capacity to handle a large volume of people. These escalators can be customized to suit specific requirements, including the option of two angles: 27.3° and 23.2°. The flexibility in angle selection allows for optimal integration into various infrastructure layouts, ensuring smooth and efficient passenger movement.

2) Step Width
The most common widths for escalator step are 24 inches (600mm), 32 inches (800mm), and 40 inches (1000mm). The wider the step, the higher the cost.

3) Rise Height (Vertical Rise)
The height of an escalator often corresponds to the vertical distance it needs to cover. Higher rise heights result in longer escalators, requiring longer escalator tracks and taller trusses, which can increase the overall cost.

Also, taller escalators may require additional structural support to ensure stability and safety. This could involve reinforcing the building’s framework, installing heavier materials, or using more robust engineering solutions. These factors can contribute to increased costs.

4) Escalator Length (Horizontal Span)
The longer the length of the escalator, the higher the price. The length of an escalator can have a significant impact on its price, as it directly affects the materials required, manufacturing complexity, installation process, and overall engineering considerations. It should be noted that the maximum length of the escalator should not exceed 50m.

● How to Calculate Escalator Length

When the angle is 35°:

Indoor Escalator L = Escalator height（m） * 1.428 + 4.905m

Outdoor Escalator L = Escalator height（m） * 1.428 + 5.105m

When the angle is 30°:

Indoor Escalator L = Escalator height (m）* 1.732 + 4.765 m

Outdoor Escalator L = Escalator height（m） * 1.732 + 4.965m

For example, when the rise height is 5 meters and the inclination angle is 35 degrees, the length of the indoor escalator can be calculated as:
L = 5m * 1.428 + 4.905 = 12.045 meters

5) Speed
When it comes to escalators, speed refers to the travel velocity of the moving steps. escalators generally have a speed of 0.50m/s, 0.65m/s, 0.75m/s, and 0.90m/s (approximately 1.6 to 3.3 feet per second). Normally 0.5m/s (1.6 feet per second). The faster the speed, the more expensive the price.

6) Horizontal Steps

The number of steps on the horizontal plane, known as the tread, can impact the price of an escalator. The tread refers to the flat portion of each step where passengers stand while being transported. Typically, there are two steps on the horizontal plane and the cost increases for escalators with more than two steps.

The inclusion of each additional horizontal step results in an approximate increase in the cost of 1600 USD.

7) Indoor or Outdoor Installation
Escalator installations are categorized as either indoor or outdoor installations. Outdoor escalators require special consideration for protection against harsh weather conditions and corrosion due to their installation in open areas. They need to be waterproof, and resistant to sunlight, oil, frost, and other weather elements. This necessitates the use of materials and coatings with high corrosion resistance and additional safety measures. As a result, outdoor escalators are typically more expensive than indoor escalators, with an average price difference of around $5,000.

8) Multiple Parallel or Crisscross
The design and configuration of escalators can vary depending on the specific requirements of a building or installation. Two common types of escalator configurations are multiple parallel escalators and crisscross escalators.
For installations of two or more escalators, paralleling is less expensive than crossover installations because it saves one face of upholstery.

9) Additional Decorations

Indeed, various additional decorations and features can impact the price of an escalator. Such as handrail strip lighting, skirt lighting, handrail strip color and material, and step material.

10) Location
The location of your home and accessibility for the installation team can also affect the price. Remote or challenging locations may involve additional logistics and transportation costs.

Escalator Dimensions

Escalator dimensions can vary depending on the specific model and manufacturer. However, here are some typical escalator dimensions for a standard commercial or public-use escalator:

• Width: Escalators usually come in three common widths: 24 inches (600mm), 32 inches (800mm) and 40 inches (1000mm)

• Length: The length of an escalator can vary significantly based on the building’s requirements and the available space. They can range from around 20 feet (6 meters) to over 60 feet (18 meters) or even longer. Maximum length cannot exceed 50m.

• Rise/Vertical Height: The rise, also known as the vertical height or elevation, is the total distance between the upper and lower landings. It can vary but is typically around 20 to 30 feet (6 to 9 meters), and a maximum of 23 meters.

These dimensions are general guidelines, and actual specifications can vary depending on the specific requirements of the building, the manufacturer, and local regulations. When installing or designing escalators, it’s crucial to comply with safety and accessibility standards to ensure the well-being of users.

What are the Escalators’ Safety Features?
