What is the tripod turnstile mechanism? The tripod turnstile entrance control comprises three at equiangular distances spaced barrier arms on a rotatable arm carrier which using a remote control barrier device can prevent or permitted, respectively, to turn in one or two turning directions. Adjacent to the arm carrier there is also a control disk with a track formation extending around its periphery with recesses between triangular cam means, spring-biased positioning means can be derolled in the track formation and against the cam means in order always to keep one of the barrier arms oriented in its home position, i.e. in a horizontal locking position. The home position of the electronic

What is a flap gate turnstile and how does it work？ What is a flap gate turnstile? A flap gate turnstile is used at security entrances or paid gate entrances in order to detect and allow access to authorized personnel one at a time and deny access to unauthorized personnel. Flap barrier turnstile is relatively less bulky than a tripod turnstile barrier (since they have a single flap or two mutually synchronized flaps, to the right and to the left of the passage), allowing the passage of pushchairs and bicycles and furthermore allowing the escape route if the flaps are left in the open position. In any case, the closure of the flap, which is motorized, occurs synchronously with a photocell

What is full height turnstile and how does it work? What is a full height turnstile gate? Full height turnstile gate is a rotary gate device that facilitates controlled passage between two separated areas which is used in controlling and/or monitoring the passage of personnel between two distinct areas as, for example, entrance and/or exit areas into, out of, or within various facilities. The full height turnstile barrier gate is constructed to extend higher vertically than the people using it in order to prevent anyone from jumping over the turnstile. Such typical turnstiles are installed in a fence or other barrier and are constructed with multiple horizontal bars extending from a verti
