Standard Operating Procedure: Daily Manlift Inspection

This Standard Operating Procedure (SOP) outlines the mandatory pre-operation inspection requirements for all mobile elevating work platforms (MEWPs), commonly referred to as manlifts. To ensure site safety and compliance with OSHA 29 CFR 1910.67 and ANSI/SAIA A92 standards, every operator must perform a documented walk-around inspection before the start of each shift or whenever the equipment changes operators. Failure to identify mechanical deficiencies or site hazards before elevating can result in catastrophic equipment failure or severe injury.

Pre-Start & Documentation

• Review Logbook: Confirm the previous operator noted no defects and that the machine is current on its annual safety inspection.
• Manual Availability: Ensure the operator’s manual and safety placards are present and legible in the storage compartment.
• Safety Gear: Verify the presence and integrity of the full-body harness and shock-absorbing lanyard.
• Environmental Scan: Check the immediate work area for overhead obstructions, drop-offs, holes, or unstable ground.

Structural & Mechanical Inspection

• Tires and Wheels: Check for excessive wear, cuts, or missing lug nuts. Ensure tires are properly inflated (if pneumatic) or free of large chunks/gouges (if solid).
• Chassis and Base: Inspect for bent steel, cracks in weld joints, or loose bolts.
• Hydraulic System: Examine hoses, cylinders, and fittings for signs of leakage or "sweating." Check hydraulic fluid levels.
• Boom Assembly: Inspect boom sections for structural damage, loose pins, or worn wear pads. Ensure cables and chains are properly tensioned and lubricated.
• Platform/Basket: Verify guardrails are secure, the gate latch closes/latches automatically, and the floor surface is free of oil or debris.

Power & Control Systems

• Fuel/Battery Levels: Confirm fuel levels are sufficient for the shift or that the battery charge indicator shows full capacity. Check for frayed or corroded battery cables.
• Control Functionality: Test the emergency stop (E-stop) button at the ground controls; ensure it cuts power immediately.
• Platform Controls: Test all joystick movements (up/down, rotate, drive) for smooth, non-jerky operation.
• Alarms and Lights: Test the motion alarm, horn, and flashing beacon (if equipped).
• Emergency Lowering: Verify that the emergency lowering system functions correctly in accordance with the manufacturer's instructions.

Pro Tips & Pitfalls

• The "Leaking Hose" Trap: A small hydraulic leak might seem minor, but under high pressure, hydraulic fluid can penetrate the skin. Never use your hands to check for leaks; use a piece of cardboard instead.
• The "Muddy Tire" Blindspot: Operators often overlook buildup inside the wheel wells. Dried mud or construction debris can fall onto the drive motor or steering linkage while elevated, causing unexpected mechanical failure.
• Battery Maintenance: Always check the water level in lead-acid batteries after charging, not before, unless plates are exposed. Never charge in an area where sparks or flames are present.
• Pitfall - Assuming "New" means "Safe": Never assume a rental or new unit is in perfect working order. Treat every machine as if it has a hidden defect until your walk-around proves otherwise.

Frequently Asked Questions

1. What should I do if I find a defect during my inspection? Immediately tag the machine as "OUT OF SERVICE," remove the key, and notify your supervisor or the maintenance department. Never attempt to operate a machine with a known safety defect, regardless of how minor it seems.

2. How often must the inspection be performed? The inspection must be performed at the beginning of each shift. If the machine is operated across multiple shifts, a new inspection must be performed by the incoming operator.

3. Am I required to wear a harness if the basket has rails? Yes. OSHA and ANSI/SAIA standards strictly require the use of a fall restraint system (harness and lanyard) attached to the designated anchor point inside the basket at all times, regardless of the height or type of MEWP.
