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
1.1
Gates shall be constructed in accordance with the provisions
given for the appropriate gate type listed, refer to ASTM F2200
for additional gate types.
1.2
Gates shall be designed, constructed and installed to not fall
over more than 45 degrees from the vertical plane, when a
gate is detached from the supporting hardware.
1.3
Gates shall have smooth bottom edges, with vertical bottom
edged protrusions not exceeding 0.50 inches (12.7 mm) when
other than the exceptions listed in ASTM F2200.
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.
1.5
An existing gate latch shall be disabled when a manually
operated gate is retrofitted with a powered gate operator.
1.6
A gate latch shall not be installed on an automatically operated
gate.
1.7
Protrusions shall not be permitted on any gate, refer to ASTM
F2200 for Exceptions.
1.8
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.
1.8.1
Vehicular horizontal slide gate. Shall not result in continuous,
unimpeded movement in either lineal direction of its travel.
1.9
For pedestrian access in the vicinity of an automated vehicular
gate, a separate pedestrian gate shall be provided. The
pedestrian gate shall be installed in a location such that a
pedestrian shall not come in contact with a moving vehicular
access gate. A pedestrian gate shall not be incorporated into
an automated vehicular gate panel.
2.
Specific Applications
2.1
Any non-automated gate that is to be automated shall be
upgraded to conform to the provisions of this specification.
2.2
This specification shall not apply to gates generally used for
pedestrian access and to vehicular gates not to be automated.
2.3
When the gate operator requires replacement, the existing gate
shall be upgraded to conform to the provisions of this
specification.
2.4
When the gate of an automated gate system requires
replacement, the new gate shall conform to the provisions of
this specification.
3.
Vehicular Horizontal Slide Gates
3.1
The following provisions shall apply to Class I, Class II and Class III
vehicular horizontal slide gates:
3.1.1
All weight bearing exposed rollers 8 feet (2.44 m), or less, above
grade shall be guarded or covered.
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.
(1.83 m) above grade, whichever is less, to prevent a 2 1⁄4 in.
(57 mm) diameter sphere from passing through the openings
anywhere in the gate, and in that portion of the adjacent fence that the
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.
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
open position or the fully closed position, shall not exceed 2
1/4 inches (57 mm). Exception: All other fixed stationary objects
greater than 16 in. (406 mm) from the gate frame shall not be
required to comply with this section.
3.1.4
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.
3.1.5
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.
3.2
The following provisions shall apply to Class IV vehicular horizontal
slide gates:
3.2.1
All weight bearing exposed rollers 8 feet (2.44 m), or less, above
grade shall be guarded or covered.
3.2.2
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.
