Cost Efficient, Robust and Reliable Tripod Turnstiles. 

Tripod turnstiles offer a cost-effective, reliable entrance control solution for internal or external use. Our TT range of motorised drop-arm turnstiles provide a visual deterrent to illegal visitors.


They are easy to use and ideal in areas where there is a large and constant flow of people.


Various cabinet options are available such as compact, bridged, and boxed turnstiles. Different tops and end panels provide all the aesthetic requirements needed for today's corporate reception areas.

Our motorised drive unit provides smooth and silent operation making it ideal for quiet locations such as school or college libraries.

The motorised mechanism automatically resets the arm to the closed position once the emergency has passed. This means there is no need to deploy staff to manually lift the tripod arms.

Turnstiles can be controller to all types of access control devices to provide secure visitor and staff management, such as:

  • RDIF card readers.

  • Bar-code scanners.

  • QR code readers.

  • Coin validators and contactless card readers.

To meet the needs of fire regulations, requirements for people with reduced mobility and large bulky items please see our SG.

Due to tripod turnstiles low cost and reliability, they are ideal for use in the leisure, and education markets.

Tripod Turnstiles or Speed Gates: Which Should You Choose?

Tripod Turnstile


Other definitions of pedestrian turnstiles are: -

  • Turnstile Gates, Turnstile Lanes.

  • Turnstile Barrier, Speed Turnstile.

  • Entrance Turnstile, Turnstyle.

  • Turnpike, Gateline.

  • Baffle Gate, Automated Gate.

  • Turn gate, Coin Operated Turnstile.

Speed Gates


Other definitions of pedestrian speed gates are: -

Turnstiles are one of the most used entrance control solutions. Used in areas with high pedestrian footfall, but relatively low security requirements. The most common areas of use include passenger terminals, stadiums, construction sites, and hotel lobbies, to name just a few.


The most common type of turnstile is the tripod turnstile, which has three arms that rotate sequentially. Each arm can rotate in two directions: clockwise and counterclockwise. As each arm rotates, it allows a single individual to pass through while blocking the next person from entering. Some turnstiles require you may have to push the tripod arm with a hand after providing proper identification.


  • They only allow one person to pass through at a time, effectively managing the footfall.

  • Difficult to force the arm open.

  • Can be used both internally and externally.

  • Easy to install various access control devices such as: -

    • Smart cards.

    • Proximity cards (RFID/NFC).

    • Key cards.

    • Barcode scanners.

    • Motion detectors.

    • Bio-metric scanners.

    • Coin and contactless readers.


  1. Low security as intruders can easily jump over or crawl under.

  2. You will need a separate Disability Discrimination Act (DDA) gate.

  3. Throughput speed is relatively low.

Speed lanes provide a high-level entrance control solution with anti-tailgating detection solution. Their design cause minimal inconvenience while offering higher security which is why they are fast becoming a popular access control solution.

Speed gate usually consists of one or two arms/obstacles that either swing open or retract into the cabinet. Typically manufactured from Plexiglas, Toughened glass, or stainless-steel frames.

Speed gate arms/obstacles can be up 1.8mt high to stop people jumping over. The lanes widths and vary from 0.5 to 1.2mt to meet requirements for people with reduced mobility and large bulky items.


  1. Speed gates offer a variety of widths, typically from 500-1200mm complying with DDA rules.

  2. They come in a variety of arm heights, typically from 900-1800mm.

  3. The operating mechanism offers higher throughput, making it suitable for areas with higher footfall.


  1. Speed gates are more expensive compared to tripod turnstiles.

  2. Retractable arms have wide cabinets especially on DDA lanes as the arms need to retract back into the cabinets.

  3. Extra care is need when used by people with reduced mobility and young children.


Tripod turnstiles and speed gates both have their advantages and disadvantages. The choice of an effective access control system will depend on end users’ unique security and access control needs.

This is why Evolve recommends that at the design stage, the specifier seek advice from the equipment manufacturer or its distributor.

It is particularly important for the equipment specifier to establish predicted user characteristics and precise user requirements such as: -

  • The volume of pedestrian traffic at different times of the day.

  • The type of pedestrian traffic, such as the elderly, the infirm, disabled persons, parents with pushchairs and young children.

  • The level of security required.

  • If users are wearing high visibility clothing.

The specifier must also consult with other relevant authorities such as fire, building control and the owner/occupier.
