What is tripod turnstile?
A tripod turnstile is a waist-height access gate with three rotating arms. It controls pedestrian flow in secure or restricted areas. Each person passes one by one, which helps prevent tailgating. Unlike swing gates, tripod turnstiles offer more physical control. They are often installed at entrances that need clear traffic direction.
Most tripod turnstiles use stainless steel, usually grade 304. This material resists rust and ensures long-term durability. Some models also support waterproofing for outdoor use. Because of their compact design, they fit well in tight indoor spaces.
Tripod turnstiles work with access control systems like RFID, face recognition, or QR code readers. When a valid credential is detected, the arm unlocks for a single rotation. After passage, the arm automatically locks again. This mechanism improves security while keeping entry smooth and organized.
Working principle of tripod turnstile
An electromechanical system controls pedestrian access through three rotating arms. When powered, the central controller links with devices like card readers or QR scanners. After successful verification, the motor unlocks one arm for entry.The user then pushes the arm to pass through. Only one rotation is allowed per valid access. This helps prevent tailgating or unauthorized entry. After use, the arm resets and locks automatically. Without valid input, the system keeps the arms locked.
Some models include emergency modes for safety. During power cuts or fire alarms, the arms drop or unlock. This allows safe evacuation in critical situations. Many systems also log entry records and support attendance software integration.Because arms rotate in one direction, the device ensures orderly, secure, and efficient flow. Its strong build and smart control suit crowded public spaces and commercial sites.

Office Buildings
Office entrances use tripod turnstiles to manage employee access. These devices integrate with ID cards or face scanners. Turnstiles improve attendance tracking and prevent unauthorized visitors. In large buildings, they help manage foot traffic efficiently.
Public Transportation
Train stations and subways install tripod turnstiles to regulate passenger entry. The system connects with ticketing or transit cards. This speeds up flow and reduces fare evasion. High traffic capacity and fast response make them ideal for busy terminals.
Stadiums and Arenas
Tripod turnstiles control entry during sports or concerts. They scan digital or printed tickets before unlocking. Only one person can enter per valid ticket. This prevents crowding and ensures a smooth entry process.
Schools and Campuses
Educational institutions install tripod turnstiles at gates or dorms. Students scan ID cards to enter secure areas. The system protects campus safety and logs entry records. It also helps prevent outsiders from entering without permission.
Advantages and Disadvantages
Advantages
- Cost-Effective
Tripod turnstiles offer reliable access control at a lower cost than other systems.They suit projects with limited budgets but high traffic demand.
- High Durability
Their stainless steel body resists corrosion and daily wear.They operate stably even in tough environments like factories or outdoor areas.
- Controlled One-Person Entry
The three-arm design limits entry to one person per pass.This helps prevent tailgating and ensures accurate access records.
Disadvantages
- Limited Accessibility
Tripod turnstiles may not suit wheelchair users or large items.They often need a side gate for accessibility compliance.
- ower Throughput
Compared to swing or flap gates, tripod turnstiles move people more slowly.This can cause queues during peak times.
- Basic Security Level
They provide basic access control but can be bypassed with force.High-security areas may need more advanced solutions.
