Completing Gate Arm Installation - HySecurity SwingSmart DC Series Programming And Operations Manual

COMPLETING GATE ARM INSTALLATION

1. To determine whether you should drill & bolt
or weld the linkage arms, you should take into
consideration site planning and future impact
to gate arm installation. Check whether fire
bans exist at your site. Fire bans do not permit
outdoor welding.
2. Paint exposed areas to prevent rusting.
1A: DRILL & BOLT: If you plan to use fasteners,
drill holes through the linkage arms. Refer to
Figure 14.
1B: WELD: If you plan to weld the linkage arms,
weld a 1/8-inch fillet around the tubing joint.
Only weld at sites where outdoor welding is
permitted.

CAUTION
For sites where incident of gate strikes are
high, HySecurity recommends setting the
elbow with a slight offset at the full close
position. Use the supplied set screw in middle
position to prevent the arm from locking. The
intent of the offset is that, upon gate strike,
the elbow will bend and the taper clamp will
slip, minimizing damage to the gearbox and
operator. Be aware if the elbow is set straight
and a gate strike does occur, the full force of
the impact will be transferred through the
linkage arms and into the gearbox causing
possible damage to the gearbox and operator.
