SAFETY Gate Construction Information Vehicular gates should be installed in accordance with ASTM F2200: Standard Specification for Automated Vehicular Gate Construction. For a copy, contact ASTM directly at 610-832-9585 or www.astm.org. 1. General Requirements 3. Vehicular Horizontal Slide Gates 1.1 Gates shall be constructed in accordance with the provisions 3.1 The following provisions shall apply to Class I, Class II and Class III given for the appropriate gate type listed, refer to ASTM F2200 vehicular horizontal slide gates: for additional gate types. 3.1.1 All weight bearing exposed rollers 8 feet (2.44 m), or less, above 1.2 Gates shall be designed, constructed and installed to not fall grade shall be guarded or covered. over more than 45 degrees from the vertical plane, when a gate is detached from the supporting hardware. 3.1.2 All openings shall be designed, guarded, or screened from the bottom of the gate to the top of the gate or a minimum of 6 ft. 1.3 Gates shall have smooth bottom edges, with vertical bottom (1.83 m) above grade, whichever is less, to prevent a 2 1⁄4 in. edged protrusions not exceeding 0.50 inches (12.7 mm) when (57 mm) diameter sphere from passing through the openings other than the exceptions listed in ASTM F2200. anywhere in the gate, and in that portion of the adjacent fence that the 1.4 The minimum height for barbed tape shall not be less than 8 feet (2.44 m) above grade and for barbed wire shall not be less than 6 feet (1.83 m) above grade. gate covers in the open position. The gate panel shall include the entire section of the moving gate, including any back frame or counterbalance portion of the gate. 1.5 An existing gate latch shall be disabled when a manually operated gate is retrofitted with a powered gate operator. 3.1.3 A gap, measured in the horizontal plane parallel to the roadway, between a fixed stationary object nearest the roadway, (such as a gate support post) and the gate frame when the gate is in either the fully 1.6 A gate latch shall not be installed on an automatically operated open position or the fully closed position, shall not exceed gate. 2-1/4 inches (57 mm). Exception: All other fixed stationary objects 1.7 Protrusions shall not be permitted on any gate, refer to ASTM F2200 for Exceptions. greater than 16 in. (406 mm) from the gate frame shall not be required to comply with this section. 1.8 1.8.1 1.9 Gates shall be designed, constructed and installed such that their movement shall not be initiated by gravity when an automatic operator is disconnected, in accordance with the following. Vehicular horizontal slide gate shall not result in continuous, unimpeded movement in either lineal direction of its travel. For pedestrian access in the vicinity of an automated vehicular gate, a separate pedestrian access shall be provided or available. The pedestrian access shall be installed in a location such that a pedestrian shall not come in contact with a moving 3.1.4 3.1.5 3.2 Positive stops shall be required to limit travel to the designed fully open and fully closed positions. These stops shall be installed at either the top of the gate, or at the bottom of the gate where such stops shall horizontally or vertically project no more than is required to perform their intended function. All gates shall be designed with sufficient lateral stability to assure that the gate will enter a receiver guide, refer to ASTM F2200 for panel types. The following provisions shall apply to Class IV vehicular horizontal slide gates: vehicular access gate during the entire path of travel of the vehicular gate. A pedestrian gate shall not be incorporated into an automated vehicular gate panel. 3.2.1 3.2.2 All weight bearing exposed rollers 8 feet (2.44 m), or less, above grade shall be guarded or covered. Positive stops shall be required to limit travel to the designed fully open and fully closed positions. These stops shall be installed at 2.
