Utilizes both eddy current damping and pneumatic damping; Patented technology results in a reduction of the vertical motion of traffic mast arms by over 90% in most situations; Ensures effective mitigation for a broad range of poles and amplitudes of vibration; Tested to over seventeen million cycles with no observable degradation in the unit or the performance of the damper; Reduces vibration on both new and existing mast arms; Reduce the cost of the overall structure by reducing the size of the pole and mast arm; Lower maintenance, inspection and repair costs; Improve safety to the traveling public by reducing the likelihood of fatigue failures; Compact, self-contained and easy to install using specially designed mounting hardware; Backed by Valmont’s engineering expertise; Watch how the Mitigator eliminates vertical movement here
