PROPER GATE DESIGN
IMPORTANT- A GATE OPERATOR CANNOT OVERCOME A POORLY DESIGNED GATE.
Since the gate is a major component of
the system, great care and concern must
be given to the gate design. USAutomatic,
LTD is not responsible for any damage to a
gate on which the gate operator is installed.
A poorly installed or misadjusted gate could
be damaged. It is the responsibility of the
installer to verify proper gate installation prior
to operator installation. As a general rule, a
gate, which is to be automatically operated,
must be stronger and smoother than one
operated manually.
• Does the gate swing smoothly without binds
or excessive resistance?
• Swing gates should swing level and plumb
to prevent the operator from having
to lift the gate open or closed.
• Swing gates should not require a wheel to
support them. Wheels create drag,
which will cause operator problems. A
wheel is generally a sign of a weak hinge
system or a weak gate frame.
• Is the gate frame of substantial strength
without excessive weight?
• Will the frame withstand normal wind load
conditions without sway or vibration?
• Will the gate close correctly without being
hand-guided or lifted to close?
• Are the hinges suited for an automatic gate
operator? We recommend bearing
type hinges to reduce friction drag.
• Will a reinforcement brace be required to
attach the linear actuator to the gate
or does a suitable cross member exist in
the gate design? See pg 11 for examples.
If any of these problems exist, they must be
corrected to achieve a reliable automatic gate
system.
Gate MUST be level
Gate should not require a
wheel for support.
Gate should not be unlevel
due to weak frame.
Gate should not be unlevel
due to unlevel post.
