StrongArm Installation and Reference 11
Installation
Attaching Barrier Arms to the Operator
1. Bolt arm(s) to operator. The maximum length for a single wood board is 14' length. Wood arms that
are longer than 14' must be twin arms bolted together near the tip.
2. Counterweights must be used for all arms over 18' in length, to assure proper performance. Verify
proper balance by following step #2 on StrongArm (HTG 320) adjustments page.
3. Tubular aluminum arms may be single side mounted up to 18’ in length. All arms over 18’ must be
mounted into a center yoke adapter. Arms longer than 24’ are aluminum/fiberglass and include
cables to make the arm more rigid, see the arm drawings for their proper location and installation.
Basic Testing
Test the operator for smooth control of the barrier arm. The arm should stop smoothly at each end of
travel. If any adjustments are necessary, carefully review the StrongArm (HTG 320) adjustments page.
Do not leave the job site without correcting an operator that is stopping abruptly on its limits or damage to
the mechanical drive components may occur.
If your operator is equipped with vehicle detectors, be certain that they are either unplugged or
connected to a loop so that they do not cause interference with the function of the machine. If the motor
turns, but nothing moves, reverse two poles of a three-phase power source, and/or verify that the bypass
valve is closed. To check the bypass valve, verify that the round black knob near the hydraulic hose
connection point on the pump is not toggled to the bypass position. See drawing HTC35 ST on page 12.
Install Accessory Items
1. After all basic functions are verified, and adjustments made, connect any accessory or external
control wiring.
2. Vehicle detectors: If vehicle detectors are to be used, review the section pertaining to detector
loop sizing and layout.
3. Button station operation: Install the push button control within sight of the gate arm. Be certain the
opening is clear before closing gate. Mount a sign, which advises that the area be clear before
operation, adjacent to button station.
4. Protection: Mount a photo eye below the arm and/or an edge sensor to the leading edge of gate
according to its manufacturers specifications.
Install Warning Signs And Safety Information Labels
1. Be sure to install all of the warning signs or labels that were supplied with this operator. If
these labels have been misplaced or lost, call your local distributor or the factory for
replacements.
