TYMETAL’s K4 crash-rated vertical lift gate is certified to ASTM F2656 M30/P1 and U.S. DoS K4 standards, confirming it will stop a 15,000-lb vehicle at 30 mph within a 1-meter penetration distance. This certification makes it suitable for government, military, and critical infrastructure sites requiring hostile vehicle mitigation at a vertical lift gate access point.

The vertical lift gate rises straight up, requiring no lateral clearance beyond the lane width and no back-clearance tail section. This makes it highly efficient for space-constrained locations such as narrow access corridors, multi-lane checkpoints flanked by barriers, and building-integrated entries where swing or slide gate geometries are not feasible.

TYMETAL’s K4 vertical lift gate system is available with hydraulic and electromechanical operator configurations scaled for the gate’s structural weight and crash-rated duty requirements. Control panels support standard access control interfaces including card readers, guard booth controls, and remote operation systems, with safety interlocks required for UL 325 compliance.

The vertical lift gate system is compatible with photo eyes, loop detectors, and presence sensors that detect obstructions in the gate’s travel path and prevent operation until the lane is clear. Redundant sensor configurations can be specified for high-security installations where false operation of a crash-rated gate poses a significant safety or liability risk.

The lift mechanism, guide rail system, and operator components should be lubricated and inspected per TYMETAL’s maintenance schedule. The structural frame and lift cable or hydraulic cylinder connections should be checked annually for fatigue and wear, and the foundation anchor system inspected for integrity to maintain the gate’s certified crash performance.
