Anti-ram crash gate

A method of crash testing an anti-ram gate, comprising:

• impacting a vehicle of substantial mass into a barrier of an anti-ram gate when the vehicle is traveling in a direction from an attack side toward a protected side;
• and
• the anti-ram gate stopping the vehicle within a distance of a closed position of the barrier, wherein the anti-ram gate comprises:
• a buttress post assembly secured in a ground comprising two buttress posts forming a barrier passage;
• a latch post assembly secured in the ground on an opposite side of a roadway from the buttress post assembly, the latch post assembly comprising two latch posts forming a latch gap;
• a vertical pin positioned in the latch gap and extending between a pair of vertically spaced apart struts;
• and
• the barrier comprising a horizontal gate beam disposed in the barrier passage and extending from a buttress end to a latch end, the buttress end having a lateral width greater than a lateral width of the barrier passage, and the latch end comprising a hook open toward the protected side, wherein the barrier is positioned in the closed position with the barrier extending across the roadway, the buttress end positioned on the opposite side of the two buttress posts from the roadway, and with the latch end located in the latch gap on the attack side relative to the vertical pin.

A method associated with a crash gate configured to guard against motor vehicles crossing in a direction from an attack side to a protected side, comprising:

• securing a buttress post assembly and a latch post assembly on opposite sides of a roadway, wherein the buttress post assembly comprises two vertical buttress posts forming a barrier passage, the latch post assembly comprises two vertical latch posts forming a latch gap, and a vertical pin positioned in the latch gap;
• the latch post assembly further comprising a pair of vertically spaced apart struts extending across the latch gap and secured to the two latch posts, the pin extending between the pair of vertically spaced apart struts;
• and
• mounting a moveable barrier in the barrier passage, the barrier comprising a rectangular frame including a horizontal gate beam extending from a buttress end to a latch end, the latch end comprising a hook open toward the protected side, wherein in a closed position the latch end is located in the latch gap.
