Anti-pinch Revolving Door
In modern commercial architecture, entrance systems must balance high-traffic efficiency with uncompromising safety standards. Our advanced range of revolving doors incorporates intelligent anti-pinch technology that actively prevents injuries without sacrificing smooth operation. Whether you need an Automatic Glass Revolving Door to showcase a transparent lobby, a robust Motorized Revolving Door for heavy-duty access control, a cost-effective Manual Revolving Door with ergonomic push force, or a Fully Automatic Revolving Door that integrates seamlessly with building management systems, each solution undergoes rigorous testing to meet global safety certifications. The anti-pinch mechanism relies on multi-beam infrared sensors and pressure-sensitive leading edges that instantly reverse the wing movement upon detecting any obstruction.
The Anti-pinch Revolving Door is engineered with a sophisticated microprocessor controller that continuously monitors the rotation pathway. Its brushless direct-drive motor delivers whisper-quiet performance while achieving a maximum rotation speed of 6 revolutions per minute under free-flow conditions. The door leafs are fabricated from 10mm tempered safety glass with a satin-anodized aluminum frame, capable of withstanding wind loads up to 2.5 kPa. Integrated safety features include an emergency collapse function that allows the wings to fold flat under manual pressure, a low-friction bearing system that ensures effortless operation even during power loss, and an adjustable sensitivity threshold for the anti-pinch response. Detailed technical specifications for our standard three-wing and four-wing models are outlined below.
- Drive System: Brushless DC servo motor with encoder feedback, integrated regenerative braking
- Safety Sensors: 12-beam vertical infrared curtain per wing; pressure-sensitive rubber profiles on all leading and trailing edges
- Control Interface: Touchscreen LCD panel with password-protected access levels; BACnet/IP communication module for smart building integration
- Power Supply: 100–240V AC, 50/60 Hz single-phase; standby power consumption ≤30W
- Emergency Functionality: Breakout wings, integrated battery backup for up to 30 minutes of slow-speed operation, integration with fire alarm system for automatic unlocking
- Durability: Tested to over 5 million operating cycles; main bearings rated for 20,000 hours continuous service
