About this file
This is a Preventive Maintenance Checklist appendix that outlines required maintenance procedures and schedules for facility equipment.
The checklist covers three primary equipment categories with specified maintenance frequencies: Hangar Doors (annual), Roll-Up Doors (semi-annual), and Dock Levelers (quarterly). For Hangar Doors, maintenance includes lubrication of bearings, hinges, chains, and drive sprockets using manufacturer-recommended grease; gear oil replacement; visual inspection of door panels, tracks, and cables; hardware tightening; and for automated doors, limit switch testing, safety system verification (photo eyes, safety edges, warning systems), brake mechanism inspection, and electrical connection checks. Weather seal inspection and replacement is also required. Roll-Up Doors require similar lubrication of moving parts using silicone spray or paste wax, mechanical inspection of slats and end locks, guide and bottom bar assessment, spring tension adjustment, and for automated doors, limit switch adjustment, belt and brake inspection, roller chain lubrication, and safety sensor testing. Dock Levelers, inspected quarterly, require pit cleaning, platform and lip inspection, concrete and curb steel assessment, warning decal replacement, weld crack inspection, fastener tightening, toe guard and bumper verification, hydraulic or air-powered system checks depending on type, fluid level and leak inspection for hydraulic systems, air bag inspection for air-powered systems, operational cycling, weather seal inspection, cross-traffic safety leg testing, and hold-down assembly verification.

Appendix C - Preventive Maintenance Checklist
1.Hangar Doors (Annual)
•Lubrication:
•Lubricate all bearings, hinges, chains, and drive sprockets with manufacturer-recommended grease to prevent rust and seizing.
•Check and replace gear oil in gearboxes as per manufacturer specifications.
•Mechanical & Structural Inspection:
•Visually inspect all door panels for signs of damage, warping, or corrosion.
•Inspect tracks and guides for proper alignment, damage, or obstructions.
•Check cables and pulleys for fraying, wear, or misalignment.
•Tighten all loose hardware, including bolts, nuts, and set screws.
•Operator & Safety System Inspection (for automated doors):
•Test and adjust limit switches to ensure the door stops at the correct open and closed positions.
•Test all safety systems, including photo eyes, safety edges, and warning systems(audible/visual).
•Inspect and test the brake mechanism on the motor.
•Check electrical connections and wiring for damage.
•Weather Seals:
•Inspect and replace weather seals and gaskets for wear or damage to ensure a proper seal.
2.Roll-Up Doors (Simi-Annual)
•Lubrication:
•Lubricate all moving parts, including springs, bearings, rollers, chains, and sprockets.
Use a silicone spray or paste wax for guides.
•Mechanical & Structural Inspection:
•Inspect all slats and end locks for damage, cracks, or deformation.
•Check the condition of the guides, bottom bar, and hood.
•Inspect and adjust the door springs for proper tension and balance.
•Tighten all fasteners, bolts, and screws.
•Operator & Safety System Inspection (for automated doors):
•Inspect and adjust limit switches.
•Inspect and adjust belts and brakes.
•Inspect and lubricate the roller chain.
•Test and inspect all safety sensors and reversing mechanisms.
3.Dock Levelers (Quarterly)
•General & Cleaning:
•Clean debris from the pit.
•Inspect the platform and lip for any bowing or damage.
•Inspect concrete and curb steel for damage.
• Inspect all warning decals and placards and replace them if they are missing or damaged.
• Mechanical & Structural Inspection:
• Inspect all welds for cracks.
• Tighten all nuts and bolts.
• Inspect the deck, lip, and rear hinge.
• Inspect toe guards to ensure they are present and in good condition.
• Inspect bumpers for wear (replace if wear is more than 1").
• Inspect and lubricate the lip and lift arm mechanisms.
• Hydraulic/Air-Powered Systems:
• For Hydraulic Levelers:
• Check hydraulic fluid levels and inspect for any leaks from cylinders, hoses, or fittings.
• Inspect and lubricate cylinder pivot points.
• Inspect all electrical connections, the control panel, and limit switches.
• For Air-Powered Levelers:
• Inspect the air bag for any punctures or abrasions.
• Inspect the blower motor, hose, and filter.
• Inspect the air bag support pallet.
• Operational & Safety Checks:
• Cycle the leveler to ensure proper operation.
• Inspect any weather seals for damage.
• Inspect and test the cross-traffic/safety legs.
• Inspect the hold-down assembly and release chains.
