PERFORM PREVENTATIVE MAINTENANCE
-
Remove upper bellows mounting hardware and clean out all debris in trough area. Remove any gravel that may have accumulated in and around bellows area. Do not apply high pressure wash to anti-skid surface. <br>
-
Inspect and lubricate the acetyl platic hinge bearing areas with a dry graphite powder, white lithium grease or marine grade grease if necessary. Excessive grease is not required on the acetyl bearings.<br>
-
Inspect and lubricate any brass bearing areas with white lithium grease or marine grade grease if necessary.<br>
-
Inspect and lubricate the cylinder clevis pin area with white lithium grease or marine grade grease if needed.<br>
-
Inspect the condition of the finish. If rust is present, wire brush and sand the area then paint with a primer and a matching color.<br>
-
Vacuum and clean the pumping unit area.<br>
-
Check paint<br>
-
What is the condition of the anti-skid surface?
-
Check oil for level, pressure, and condition in the HPU (Recommended oil: Mobil EAL 224)<br>
-
If oil is contaminated, report and recommend replacement immediately (Recommended oil: Mobil EAL 224).<br>
-
Check barrier for operation through normal cycles.<br>
-
Adjust barrier speed to ensure proper operation. Check original submittal documents for normal operating speed for up and down.<br>
-
During the opening and closing cycles, verify the barrier operates smoothly and does not bind. Also verify that the barrier does not hit with excessive force when it contacts its full-open or full-closed positions. Adjust barrier speed if necessary.
-
Check the hydraulic pumping unit for leaks at all points.
-
Visually inspect the operation and electrical contacts.<br>
-
Tighten electrical contacts if required.
-
Check, adjust, and tighten all sensors (limit switches, proximity switches).
-
If applicable, check traffic lights and replace any burned bulbs or LEDs.
-
Check safety devices (loop, IR, etc.) for proper operation and report any anomalies (if applicable).
-
Check the PLC for normal operation of all logic and functions.
-
Inspect hinge pin areas for debris and clean.
-
Verify bellows is not worn and operates correctly when barrier is closed and opened.
-
Inspect the cylinder and report abnormalities.
-
Check the operation of the control panel(s).
-
Turn the master power switch on the control circuit box to the OFF position.
-
Inspect the hydraulic system for signs of oil leaks. CAUTION: The hydraulic system when in operation is under extreme pressure. Verify pressure on the barrier is completely relieved prior to removal of any hydraulic fittings.
-
Check the hoses for wear or abrasion.
-
Check all fittings for tightness.
-
Inspect the oil level in the HPU and add if necessary. Typically, th oil level should be 1-1.5 inches below the top of the sight glass on the outside of the reservoir, or about 6 inches below the top of the tank. Environmentally safe oil such as Mobil EAL 224 may be used.
-
Inspect the hydraulic oil for dirt or water contamination. If water is present, or oil is light brown in color, correct contamination source and replace oil if necessary.
-
Measure the resistance in any traffic loops and log the measurements and report anomalies (if applicable
-
When the inspection is complete, turn on power and test cycle the barrier to verify operation and control.
-
Replace the hydraulic fluid and filter IF last replaced a year or more ago.
-
Update the operation and maintenance log.
