2.2.7 Make the final concrete pour, again making sure the axle height does not
change and remain level and plumb. Remove any concrete that might have
splattered inside the exposed conduits.
2.2.8 After the concrete has set, install the roller wheels, collars and nuts onto the
axles if not previously installed. Place two collars (spacers) on each side of
the shaft, then the wheel, then another collar, and finally the nut. Adjust the
wheels and axle nuts so there is no side play in the wheels, but yet they can
still be turned easily by hand. Tighten set screw on the nut. Grease the wheel
bearings using the grease fittings. The wheels may be pre-greased. Be
careful not to over-grease the bearings.
NOTE: It is critical that the axle nuts are secure prior to the gate beam
installation.
2.2.9 Install the four guide wheels into the guide wheel receivers on the wheel
stanchion. Leave the bolts fully backed off to allow the guide wheels to
insert completely into the receivers.
2.4 Installing the Gate and Motor Components
Perform the following steps to install the gate (gate leaf), motor, and limit switches on the
motor/main stanchion.
2.4.1 Lift the gate assembly using a crane or forklift. Guide the gate onto the first
set of roller wheels, with the wheels fitting between the I-beam and the
channel. Push the gate onto the second set of roller wheels.
2.4.2 Move the gate by hand to the halfway position. Install the end plates and
rubber stops onto the ends of the gate.
2.4.3 Slide the gate through about ⅔ of its travel. If the gate binds, adjust the guide
roller wheels to eliminate the binding.
2.4.4 Mount the motor and gear assembly. Mount the motor on the wheel post
closest to the roadway opening and on the side between the two single posts.
Leave the motor mount in the down position with the bolts slightly loose
until the motor rotation and limit switches have been tested.
2.4.5 Mount the limit switches.
