4.2.2 Horizontal and Vertical Torque Adjustment & Counterweight Guidelines
This procedure requires the use of the following tools:
•
•
•
Prerequisites
Gate assembly fully installed.
•
Gate arm and arm lights installed.
•
• Gate arm in horizontal position.
Counterweights installed per Table 4-2.
•
• Optional: 12 VDC connected to battery input terminals.
A. Set Horizontal Torque (no power is applied to the mechanism)
1. Install the torque wrench onto the ½" hex of the gearmotor output shaft (see Figure 4.4). This
is the same location as where the lock bar is applied.
2. Turn the torque wrench clockwise (when viewed from the gearmotor) until the segment gear
is no longer resting on the horizontal buffer.
3. Hold the torque wrench stationary and ensure the gate arm is not bouncing. Read the torque
value indicated on the torque wrench.
4. Slowly release tension on the torque wrench and allow the segment gear to rest on the
horizontal buffer.
5. Repeat Steps 4 – 6 a total of three times to obtain an accurate, average reading for the
horizontal torque.
6. Compare the value from Step 5 to Table 4-2:
a. If the horizontal torque measured is lower than indicated in the table, move the
counterweights closer to the main shaft.
b. If the horizontal torque measured is higher than indicated in the table, move the
counterweights further from the main shaft.
c. If the horizontal torque measured is within the range indicated in the table, tighten the
adjustment nuts on the counterweights, tighten the counterweight stud plate nuts on
the opposite side from the counterweights, and proceed to set the vertical torque.
B. Set Vertical Torque (power can be applied to the mechanism but it is not required)
1. Raise the gate arm to the vertical position either manually or automatically:
SIG-QG-21-01
Version: A
a torque wrench with a range of 20 to 250 inch-pounds, that has a digital
readout with a tracking mode.
a ½" socket for the torque wrench.
a 5/16" wrench or a ratchet with a 5/16" socket (for application to the brake
end of the gearmotor).
