NOTE:
Articulating Arm Option is only available on the old style two cover swing arm shown here.
The articulating arm assembly uses a spherical
rod end at the elbow and at the bracket mount.
Situations where you might use this option include:
z
The operator pad or gate is not level. The
spherical rod ends on the articulating arm
forgive minor discrepancies where the hardware
may not be perfectly plumb.
z
The gate arm is not horizontal.
By ordering the articulating arm assembly for use
in these situations, the binding stress between the
operator and gate hardware is reduced.
When installing an articulating arm assembly, be
sure to take into account the following guidelines:
NOTICE
Articulating Arm Option is only available on
the old style two cover swing arm shown here.
NOTICE
Although some sites necessitate fastening a
gate arm to the gate at an angle, HySecurity
does not recommend it. The preferred method
is an installation where the gate arm remains
horizontal throughout gate travel.
z
A gate must be neutrally balanced. To comply
with ASTM F2200 General Requirements, a gate
must be designed, constructed and installed in
such a way that its movement is not initiated by
gravity when the gate operator is disconnected
or loses power.
z
The over-extension stop on the standard
HySecurity gate arm does not exist on the
articulating arm. To avoid hyperextension,
mount the arm so a slight bend at the elbow
joint is maintained in the gate closed position.
This slight bend may prevent damage to the
operator during a gate strike because it allows
the elbow to bend properly and permits the
taper clutch to slip thereby reducing the impact
to the operator.
z
Due to the flexibility in the elbow joint, only one
pinch protection cover is used.
CAUTION
If the gate arm is mounted at a slight angle,
test the operation of the gate several times. Be
sure to check for clearance issues. If possible
pinch points exist, make sure to adjust the
gate arm and eliminate any clearance issues
or pinch points.
