MECHANICAL RELIABILITY

Heavy-Duty Tripod & Rotogate Anatomy

Unlike light-duty retail security gates, transit-grade tripod barriers must survive millions of impacts, aggressive tailgating attempts, and extreme weather.

Fail-Safe Drop-Arm Hub

Centrifugal or solenoid-released mechanical drop arm collapses downward instantly during fire alarms or power outages to create a 100% unobstructed evacuation corridor.

Hydraulic Rotation Damper

Heavy hydraulic shock absorber cushions arm deceleration at the end of each 120-degree rotation, eliminating mechanical clatter and extending bearing longevity.

Hardened Tool Steel Cams

Precision CNC machined locking pawls and indexing ratchet cams heat-treated to Rockwell C56–60 to prevent groove wear after millions of cycles.

Vandal-Resistant Housing

Formed from 10-gauge (0.135") 304 or 316 stainless steel with concealed internal hinge pins, high-security Medeco cam locks, and rain baffles.

Frequently Asked Questions

How does the automatic drop-arm reset after an alarm?

Depending on client requirements, we manufacture both manual lift-to-lock drop arms (which staff physically click back into place) and fully motorized automatic re-arming mechanisms that rotate and lift the fallen arm back to horizontal position once emergency power is restored.

Can Fabtron supply replacement parts for older transit turnstiles?

Yes. We maintain original tooling, machining programs, and engineering drawings for genuine Perey Turnstiles and standard industrial tripod barriers installed across North American transit networks and stadiums.
