Swing door elevator

What is an automatic door elevator?

Swing Door Elevator is a type of elevator designed with a door system that can automatically open in an outward or inward direction, similar to a traditional door. Unlike sliding doors, swing doors do not use a horizontal sliding mechanism but use a hinge or rotating mechanism, creating an opening and closing motion in the direction of rotation.

This type of elevator is often used in small spaces, where there is not enough space to install sliding doors or in projects that require synchronization with classic and luxurious architectural design. Automatic opening doors are often made from durable materials such as stainless steel, tempered glass or aluminum alloy to ensure high durability and safety.

In addition, the integrated safety sensor system helps the door operate accurately and minimizes the risk of collision when opening and closing. The automatic door elevator is especially suitable for civil or commercial buildings with moderate traffic, providing flexibility and high aesthetics in the overall design of the building.

How does an elevator with automatic doors work?

The operating principle of the automatic door opener is based on the combination of electronic and mechanical systems, allowing the elevator door to automatically open or close safely, accurately and conveniently. Below are the detailed steps describing the operating principle:

Receiving control signals

When the user presses the floor call button or when the floor stop signal is activated, the central control system immediately receives the command and processes the information. Based on the received signal, the system will quickly transmit the command to the door control motor, starting the door opening or closing process accurately and synchronously. This process is performed automatically with high sensitivity, ensuring accuracy and timely response to the user's travel needs. Thanks to the flexible signal reception and processing mechanism, the system not only brings convenience but also contributes to optimizing the performance of the elevator, effectively meeting the requirements of use in public and private environments.

Door motor operation

Upon receiving a signal from the central control system, the door motor (door operator) begins to perform the task of converting electrical energy into mechanical force to operate the door system. For automatically opening doors, the motor will generate a strong and precise rotation force, transmitting this force to related mechanical components such as the hinge shaft or lever. Thanks to the smooth coordination between the components, the door will be opened at a certain angle, ensuring smooth movement, no noise and safety for the user. The operation of the door motor is optimally designed to maintain high performance, meeting the requirements of continuous operation in high-frequency environments such as office buildings, shopping centers or other public works.

Door movement

Under the influence of the door motor, the door starts to move according to the pre-designed mechanism. Depending on the type of door, the door can rotate around the hinge or move through the lever system, opening in a fixed direction, usually outward or inward. This process is carried out smoothly thanks to the perfect combination of mechanical components and the integrated damping mechanism. The damping mechanism plays an important role in controlling the speed of movement, minimizing impact when the door reaches the stopping point, while minimizing the noise generated. As a result, users can experience a quiet and comfortable space, even in areas with high frequency of use.

Safety sensor

During the process of opening or closing the elevator door , the safety sensor system is activated to ensure safe and efficient operation. This sensor is designed to continuously monitor and detect obstacles that appear within the operating range of the door. When the sensor detects an obstacle, the control system will immediately respond by pausing the door movement or reversing to avoid collision. This mechanism not only prevents dangerous situations but also ensures maximum safety for users, especially in environments with children, the elderly or crowded public areas. This is an indispensable feature, contributing to increased convenience and reduced risks during elevator operation.

Automatic closing

After the door is completely opened, the elevator system will automatically switch to standby mode for a short pre-programmed period of time, long enough for users to easily move in or out of the cabin. This period of time can be flexibly adjusted to suit each usage environment such as office buildings, hospitals or shopping malls. When the waiting time ends, the central controller will send a signal to the motor, activating the door closing mechanism. The motor will gently operate to return the door to its original position smoothly, ensuring safety and minimizing noise. The automatic door closing feature not only saves time but also contributes to maintaining the continuous operation efficiency of the elevator.

Safety lock

The safety lock is an important part of the elevator's automatic door opening system, helping to protect users and ensure safety during operation. When the elevator door is completely closed, the safety lock will be automatically activated, locking the door to prevent the door from opening while the elevator is moving between floors. This helps to avoid dangerous situations such as the elevator door opening while the elevator is still operating, minimizing the risk of accidents for users. The safety lock is an essential protection mechanism, ensuring that the door can only be opened when the elevator has completely stopped at the correct floor position. Thanks to this feature, the lock not only helps to improve the safety of the elevator but also creates peace of mind for users when using elevator services, especially in large projects where the number of users is very large.

This principle is designed to ensure that the automatic opening door operates stably and smoothly, meeting the requirements of use in buildings such as offices, hotels, or high-end houses, where aesthetics and convenience are top priorities.
