Tower Crane Maintenance: Best Practices & Safety Protocol

Tower Crane Maintenance: Best Practices & Safety Protocol

I. Critical Importance of Maintenance

Proper maintenance directly impacts equipment lifespan and construction safety. Statistics show:

• 80% of tower crane accidents stem from improper maintenance

• Regular maintenance reduces unexpected failures by 60%

II. Core Maintenance Procedures

1. Daily Maintenance (Per Shift)

• Structural Inspection

• Check welding seams and deformations on mast sections/boom structures

• Tighten high-strength bolts (replace after 3 uses)

• Lubrication Management

• Apply #4 calcium-based grease to slewing rings every 80 hours

• Maintain oil levels in gearboxes (replace turbid oil immediately)

  Electrical Systems

• Clean controller contacts; inspect cable insulation

Test safety devices: moment limiter, height limiter

2. Periodic Maintenance

3. Seasonal Adaptations

• Winter Shutdown:

• Clear snow from tracks; increase counterweights by 10%

• Switch to -20# low-temperature hydraulic oil

• Rainy Season:

• Seal motor junction boxes; install rain covers

III. Safety Management Protocol

1. Qualification Requirements

• Operators/maintenance staff must hold valid certifications

2. Work Zone Control

• Establish 6m isolation zones; halt operations at ≥12.5m/s winds

3. Fault Response

• Implement "Detect-Report-Resolve-Verify" procedure

• nes; halt operations at ≥12.5m/s winds

IV. Smart Maintenance Solutions

1. IoT Monitoring

• Vibration sensors detect gearbox anomalies (±0.02mm accuracy)

2. Digital Platforms

• QR-code equipment profiles with auto-lubrication reminders

3. AR Assistance

• Smart glasses identify loose bolts (<3cm positioning error)

V. Prohibited Practices

• Never disable safety limiters or modify program parameters

• Avoid non-OEM parts (especially high-strength bolts)

• Prohibit electrical repairs without power cutoff
