How is a double full height turnstile mechanism?
· There are two separate mechanism on the double turnstile, each of them is for per passage. · Double Full Height Turnstiles often use ratchet mechanisms to allow the rotation of the stile in one direction allowing ingress but preventing rotation in the other direction. · A lock up arm ( pawl ) is used to locking at the double full height turnstile mechanism. · Solenoids push or pull the pawls. · A drive spring provides the double turnstile arm to return its correct position when passage occurs. Drive spring mechanism has a spring inside its housing used to store mechanical energy. If this spring is compressed more than desired, force applied to turnstile arm rotating force will increase. · Shock absorber provides the smooth operation of the double t...
