when a manually operated gate is retrofitted.
4.1.6 A gate latch shall not be installed on an
automatically operated gate.
4.1.7 Protrusions shall not be permitted on any
gate. Consult ASTM F2200 for exceptions.
4.1.8 Gates shall be designed, constructed and
installed such that their movement shall not
be initiated by gravity when an automatic
operator is disconnected.
4.1.9 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.
4.1.10 Any non-automated gate that is to
be automated shall be upgraded to conform
to the provisions of this specification.
4.1.11 This specification shall not apply to
gates generally used for pedestrian access
and to vehicular gates not to be automated.
4.1.12 Any existing automated gate, when
the operator requires replacement, shall be
upgraded to conform to the provisions of
this specification in effect at that time.
4.2 Vehicular Horizontal Slide Gate Requirements
4.2.1 The following provisions shall apply
to Class I, Class II and Class III vehicular
horizontal slide gates:
4.2.1.1 All weight bearing exposed rollers
8 ft (2.44 m), or less, above grade shall be
guarded or covered
4.2.1.2 All openings shall be designed,
guarded, or screened from the bottom
of the gate to the top of the gate or a
minimum of 72 in. (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.
4.2.1.3 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 in. (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.
4.2.1.4 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.
4.2.1.5 All gates shall be designed with
suffi cient lateral stability to assure that the
gate will enter a receiver guide. Consult
ASTM F2200 for details on various gate
panel types.
