Elevator Door System Parts

Elevator Door System Parts

A key part of an elevator’s vertical transport system is the door. The average elevator opens and closes 200,000 times per year, which can cause lots of wear and tear on the hard-working components of the doors.

This equipment needs to be maintained regularly by a certified technician. If not, your elevator may break down and require expensive service calls.


Rollers are an important part of elevator door system parts that help the doors open and close smoothly. They also help prevent accidents by preventing the panels from dragging along the car.

Elevator doors have to be adjusted and maintained regularly in order to function properly. Without regular maintenance, the doors may open unevenly or not close at all. This can result in scratches and dents on the inside of the doors that could result in costly refinishing costs.

One way to avoid these problems is to use a heavy-gauge formed track and reinforced nylon resin rollers. This type of track is proven to reduce noise and enhance the life of the entire elevator door system.

Another way to avoid accidents is to use the correct personal protective equipment (PPE) when operating a roller or other elevator door system parts. This is especially important when working with metal or other high-temperature material.

To help prevent accidents, the operator can wear a workshop apron, gloves, protective headgear, and heat and spark resistance glasses. This can help prevent loose clothing from getting caught in the rollers or being melted by high temperatures.

The operator can also use the right tools and materials to do the work. This can help avoid accidents and dents on the elevator door as well as expensive refinishing costs.

To further help prevent accidents, an elevator door system can include a vane that fits between two roller assemblies on the hall door when the car door is at the floor. The movement of the vane actuates a switch that inhibits the car door from moving, allowing the hall door to open. The system can also include a number of up thrust rollers that rotatably engage the bottom edges of the hanger track to aid in the smooth motion of the doors.


There are a lot of moving parts in the elevator door system. It is a good idea to have your technicians inspect and clean all of the parts. Keeping an eye out for wear and tear on rollers, links, and linkages will help ensure that your doors function as designed.

One component that deserves special attention is the gib. These devices are a bit of a mystery to most people, but they are vital to elevator safety. They have a plastic part that sticks into the sill and a metal part that keeps the door from slipping off the track. The best part is that these parts are relatively inexpensive to replace if needed.

What is more, the most efficient way to manufacture these tidbits of trivia is to buy them in bulk. This way, you Elevator Door System Parts can keep your elevator running smoothly and save your budget at the same time. Lastly, the biggest drawback is that these parts have to be shipped to your destination so if you want to get it done right the first time around you should be sure to order them well in advance. That way, your technician can get the job done quickly and efficiently.


Linkages are used in elevator door systems to connect mechanical parts, such as the hoistway doors and car doors, together. They can help to ensure that the doors open and close properly, preventing accidents.

Typically, linkages are designed with one or more rods and couplings that attach to an end of each arm of the mechanism. These rods and couplings may be made from elastomeric material, a universal joint, or a combination of these materials.

The rods and couplings of a linkage work in conjunction with the door arms, such as the crank arm, to move the doors. This allows the door arms to be adjusted and opened and closed without having to remove or replace any of the actual hinges on the door.

A common problem with linkages is that they can become loose over time, or even break. This can be avoided by inspecting them regularly and tightening them as needed, to prevent them from slipping or becoming loose.

Another problem with linkages is that they can become stuck or jammed, especially when opening and closing the door. This can cause the door to bang and make noise, which can be dangerous.

To avoid these problems, linkages should be modeled using computer software, such as SolidWorks. This can allow us to determine how the linkage works, and can also allow us to animate the motion of the space-filling parts that make up the linkage.

In addition, a linkage can be analyzed to determine how fast the mechanism moves, and this information can be graphed Elevator Door System Parts as a function of time or angle. This is particularly useful for linkages that are difficult to analyze without a computer.

Electric Motors

Electric motors are a crucial part of the elevator door system. They are used to move doors, as well as the lift itself. They are available in AC and DC varieties, and can be brushed or brushless. They may also have single-phase, two-phase or three-phase power.

When selecting an elevator motor, it’s important to consider its power rating and torque capability. The motor will need to be able to develop enough starting torque to move the elevator car through a full cycle of travel.

There are several types of electric motors that can be used in elevators. Some of the most common are squirrel cage and slip ring induction motors.

They are available in a variety of sizes and can be cooled with either air or liquid. They are rated for use with belted hydraulic pump systems, making them a great option for your next elevator upgrade project.

Elevator doors are made up of dozens of different parts, so routine maintenance is critical to keeping them working properly. Encoders help to monitor the doors, ensuring that they open and close properly.

These encoders also play an important role in the elevator governor system, which prevents the car from going over a certain speed. The encoders provide feedback to the controller, allowing it to recognize when the car is approaching its limit and trigger a safety device.

A pair of linear motor primaries are fixedly attached to a pair of door hangers and a motor secondary is flexibly mounted on a header bracket secured to the elevator car. A pair of swivel joints secure the ends of the motor secondary to the header bracket, compensating for misalignment and twisting of the elevator car doors.

Safety Devices

Safety devices are components that work in conjunction with elevator door system parts to prevent accidents. They monitor a number of factors such as car speed and position, as well as the state of door-locks. This information is then relayed back to the elevator’s controller to ensure that everything is running properly and safely.

One type of safety device is a door sensor, which detects if someone is in the way of the elevator’s doors. This can be a good safety feature for people with disabilities who may need help entering the elevator. These sensors are also designed to reopen the doors if they come in contact with an object.

A second type of safety device is a 3D door detector, which uses sound waves to scan a 3D area near the open elevator doors. These sensors are very rare in modern elevators, but they are very useful for preventing accidents.

These types of door sensors can be found on a number of different brands including Otis, Schindler and Kone. They usually have LED light lamps inside that signal door movement, flashing green for opening and red for closing.

In addition, some of these door sensors have a beeping sound when they detect an object or obstacle in the way of the elevator doors. This can be used to prevent people from blocking the doors (by sensor system setting).

A third type of safety device is a door-opening control, which can be placed on an elevator’s hoistway side doors and will open the door for a preset amount of time. This can be a good safety feature, especially for buildings that have heavy foot traffic.
