The YD-R138SG Three Arm Tripod Turnstile Gate is a high-security pedestrian access control device engineered to manage high-traffic pedestrian flow. Operating through a heavy-duty three-bar rotating mechanism, the tripod turnstile enforces strict one-person-per-passage access, effectively preventing unauthorized entry and tailgating. Built with premium weather-resistant housing and a high-performance brushless motor drive, this compact security gate seamlessly integrates with modern ticketing, biometric, and access control systems to provide reliable crowd management in demanding indoor and outdoor environments.
Core Features & Technical Advantages
Precise Access Control & Anti-Tailgating
The YD-R138SG tripod turnstile controls pedestrian entry and exit via three rotating metal bars that permit only one person to pass at a time. The robust mechanical mechanism accurately detects tailgating attempts and can trigger alarms, allowing software-configurable single-direction or dual-direction authorization modes.
Universal System Integration & Scalability
Designed as an open-platform security solution, the YD-R138SG easily integrates with diverse verification methods. It supports seamless connectivity with ID/IC card readers, QR code scanners, fingerprint modules, and advanced facial recognition terminals, making it highly adaptable to automated ticketing and security auditing.
Industrial Durability & Brushless Motor Drive
Constructed with standard 304 stainless steel or high-strength cold-rolled carbon steel, the housing delivers excellent rust resistance, long-term durability, and stable outdoor adaptability. The internal brushless motor drive ensures ultra-low power consumption and an extended operational lifespan exceeding 5 million cycles.
Emergency Evacuation Capability
Engineered with an automatic unlock and mechanical drop-arm safety function. During power outages, building fire alarms, or emergency situations, the barrier arms automatically unlock and drop to create an unobstructed free-passage lane for rapid and safe pedestrian evacuation.
Space Efficiency & User-Centric Design
Featuring a highly compact chassis design, the YD-R138SG easily fits into narrow corridors and restricted entry footprints while maintaining an aesthetic profile. It includes an emergency passage override button for exceptional operational circumstances and supports customizable housing colors and corporate branding.
