Heavy Duty Automatic Sliding Door Opener

Video

Heavy-duty automatic sliding door operators are engineered for demanding applications where door size, weight, and traffic volume exceed the requirements of standard automatic door systems. Suitable for commercial building entrances, hotels, office towers, airports, transportation hubs, and other public facilities, the system delivers smooth operation and reliable performance.

The operator integrates the drive system, controller, and auxiliary control equipment into a complete automation solution. Depending on project requirements, it can be connected to activation devices, access control systems, safety devices, centralized control systems, and building automation platforms. By matching the operator configuration to the door dimensions, operating conditions, and traffic requirements of each project, the system helps ensure stable operation and long-term service life.

Track lengths, access control accessories, and selected system components can also be customized to suit specific installation requirements.
