How to extend the lifespan of an aluminum alloy mast lift platform？

I. Daily Maintenance and Inspection

Cleaning and Corrosion Prevention 

· Surface Cleaning: 

Wipe the mast, platform, and guardrails with a soft cloth to prevent corrosion of the aluminum alloy surface from mud, sand, or chemical residues (e.g., acid rain, salt spray).

· Drainage Hole Inspection: 

Clear water drainage holes inside the mast to prevent water accumulation and rust, especially in coastal or high-humidity environments.

· Lubrication Protection: 

Spray rust-preventive lubricant (e.g., WD-40) on exposed metal joints.

Key Component Inspection

· Fasteners: 

Check daily for loose bolts or nuts (focus areas: outriggers, mast connections).

· Chains/Steel Cables: 

Inspect for wear, deformation, or broken strands, and ensure even tension.

· Hydraulic System: 

Check for leaks in oil lines and verify hydraulic oil clarity (normal color: transparent light yellow).

II. Periodic Deep Maintenance

Lubrication Management (Every 50 Hours or Weekly)

· Chains/Guide Rails: 

Apply lithium-based grease evenly to prevent dry friction.

· Bearings and Pulleys: 

Inject high-temperature grease to ensure smooth rotation.

· Hydraulic Valve Assembly: 

Clean and apply silicone grease to prevent seal aging.

Power System Maintenance

· Electric Models:

  Battery: Perform a deep discharge once a month, maintaining charge between 20%-80%.

  Motor Carbon Brushes: Check wear every 500 hours; replace if less than 1/3 remains.

· Hydraulic Models:

  Hydraulic Oil: Replace every 1000 hours or annually (recommended: ISO VG46 anti-wear hydraulic oil).

  Filter: Replace the hydraulic oil filter simultaneously to prevent valve blockages from impurities.

Safety Device Testing (Monthly）

· Fall Arrester: Manually trigger to test the locking function, ensuring a response time of <0.3 seconds.

· Limit Switch: Simulate overload conditions to verify sensitive power-off protection.

· Tilt Sensor: Calibrate with a level; recalibrate if the error exceeds ±1°.

III. Long-Term Shutdown and Storage

Shutdown Preparation

· Fully retract the mast and release hydraulic system pressure.

· Disconnect the battery's negative terminal, fully charge it, and store separately.

· Inflate tires to 120% of rated pressure to prevent deformation.

Storage Environment

· Indoors: Dry, well-ventilated area with relative humidity <60%, away from acidic or alkaline corrosive gases.

· Outdoors: Cover with UV-resistant tarpaulin; elevate the mast base by 10 cm to prevent moisture.
