Description
The TT‑DM3 Hydraulic Damping Module adds smooth, controlled motion to 3‑arm turnstile mechanisms. Designed to enhance pedestrian flow and user comfort, this retrofittable module progressively damps the second half of the turnstile’s rotation to deliver a fluent, predictable motion. The first half of the sweep remains free, while the latter portion engages continuous damping to prevent the arm from swinging back abruptly or contacting users at the heels (a common issue with undamped rotations). Built with a patented hydraulic system that performs consistently across temperature variations and field conditions, the TT‑DM3 is engineered for durability (tested for 1 million cycles) and easy installation on compatible 3‑arm turnstile mechanisms. It’s a simple yet highly effective part for improving the feel and safety of pedestrian gates.
Suited for 3‑arm (120°) turnstile mechanisms that support modular upgrades; commonly used for smoother motion and controlled rotation.
