Crane Maintenance Checklist

As essential heavy-duty equipment, cranes frequently handle demanding loads, making their components prone to wear over time. Regular maintenance ensures optimal performance and operational safety. Key maintenance areas include:

1. Lubrication System

Lubrication significantly impacts operational efficiency and service life. Proper lubrication reduces friction, prevents premature wear, and ensures safe operation. Maintenance personnel should:

• Regularly inspect all lubrication points
• Replenish or replace lubricants based on service intervals
• Prioritize moving parts: shafts, bearings, and friction surfaces
• Adjust lubrication schedules based on usage intensity and environmental conditions

2. Wire Rope Inspection

• Check for broken wires, corrosion, or deformation
• Replace immediately if damage exceeds discard criteria
• Recommended types: phosphated coating, galvanized, or bare steel wires

3. Lifting Attachments

• Inspect hooks, shackles, and connectors for cracks or deformation
• Conduct periodic load testing

4. Sheave Assembly

• Examine groove wear patterns
• Check for rim damage or jamming issues
• Ensure smooth rotation on axles

5. Wheel Maintenance

• Measure flange and tread thickness
• Replace wheels if wear exceeds 10% of original thickness
• Resurface treads if diameter variation exceeds D/600 or deep scratches appear

6. Brake System Verification

• Perform shift-level inspections
• Confirm precise actuation without sticking pins
• Ensure equal brake shoe clearance when released
• Maintain full contact between shoes and drum
