Crane Wheels

Crane Wheel Replacement

Changing a crane wheel typically involves the following steps:

1. Safety Precautions: Prioritize safety by ensuring the crane is properly secured and immobilized before attempting to change a wheel. Follow lockout/tagout procedures and take appropriate measures to prevent the crane from moving or accidentally operating during the wheel replacement process.

2. Equipment and Tools: Gather the necessary equipment and tools for the wheel replacement. This may include a crane jack or lifting device, appropriate wrenches or socket sets, wheel pullers, and any other specialized tools recommended by the Asan Cranes.

3. Lift the Crane: Use a crane jack or lifting device to raise the section of the crane where the wheel needs to be replaced. Ensure the crane is lifted to a safe and stable height, allowing sufficient clearance to remove and install the wheel.

4. Remove Fasteners: Identify and remove the fasteners that secure the wheel to the axle or wheel hub. These may include bolts, nuts, or other types of fasteners. Use the appropriate tools to loosen and remove the fasteners, ensuring they are safely stored for reinstallation or replacement.

5. Remove the Old Wheel: Carefully slide or pull the old wheel off the axle or wheel hub. Depending on the design of the crane wheel, it may require additional steps such as using a wheel puller or applying lubrication to facilitate removal. Follow the manufacturer's instructions or guidelines for the specific type of wheel being replaced.

6. Prepare the New Wheel: Ensure the replacement wheel matches the specifications and requirements of the crane. Clean the axle or wheel hub area and inspect it for any signs of damage or wear that may need to be addressed before installing the new wheel.

7. Install the New Wheel: Carefully position the new wheel onto the axle or wheel hub. Align the wheel properly and ensure it fits securely in place. Reinstall the fasteners and tighten them to the specified torque values, following the recommended tightening sequence if provided.

8. Lower the Crane: Gradually lower the crane back to its resting position, ensuring the new wheel is properly seated and aligned. Take caution not to damage the wheel or other components during the lowering process.

9. Test and Inspect: After the wheel replacement, conduct a thorough inspection of the wheel, axle, and surrounding components. Ensure all fasteners are properly tightened, and the wheel rotates smoothly. Test the crane's movement and verify that the replaced wheel functions correctly.

10. Documentation: Maintain records of the wheel replacement, including the date, details of the replacement process, and any relevant notes or observations. This documentation can help track maintenance history and provide valuable information for future inspections or replacements.

It's important to note that the specific process for changing a crane wheel may vary depending on the crane model, wheel type, and manufacturer recommendations. Always refer to the manufacturer's instructions and guidelines for the proper procedure and any specific considerations for your crane. If you are unsure or unfamiliar with the process, consult with a qualified crane service technician or seek professional assistance.

Controlling Crane Wheels

Controlling crane wheels involves ensuring their proper alignment, condition, and maintenance. Here are some steps to help control crane wheels:

1. Visual Inspection: Conduct regular visual inspections of the crane wheels to check for signs of wear, damage, or abnormalities. Look for cracks, flat spots, uneven wear patterns, or any other visible issues that may affect wheel performance.

2. Wheel Alignment: Check the alignment of the crane wheels to ensure they are parallel to each other and properly aligned with the crane rails. Misaligned wheels can cause excessive wear, instability, and increased stress on the crane structure. Adjust the wheel alignment as needed.

3. Wheel Flange Lubrication: Apply suitable lubricants to the wheel flanges to reduce friction and wear. Lubrication helps prevent wheel flange damage and ensures smooth movement along the crane rails.

4. Wheel Tread Lubrication: Lubricate the wheel tread surfaces to reduce friction and wear between the wheels and the crane rails. Proper lubrication helps maintain smooth and efficient movement of the crane.

5. Wheel Bearing Maintenance: Regularly inspect and maintain the wheel bearings according to the manufacturer's recommendations. This may involve lubrication, cleaning, or bearing replacement as necessary. Properly functioning wheel bearings contribute to smooth wheel rotation and reduce the risk of failures.

6. Wheel Cleaning: Keep the crane wheels clean by regularly removing debris, dirt, or other contaminants. Clean wheels help prevent damage to the wheel tread and ensure optimal contact with the crane rails.

7. Wheel Replacement: If a wheel is significantly worn, damaged, or showing signs of fatigue, it may need to be replaced. Follow the manufacturer's guidelines for wheel replacement, including selecting the appropriate wheel type, size, and load capacity.

8. Regular Maintenance: Incorporate regular wheel maintenance into the crane's overall maintenance schedule. This includes cleaning, lubrication, inspection, and addressing any identified issues promptly.

9. Professional Inspections: Periodically engage the services of qualified crane inspectors or specialized maintenance professionals to conduct in-depth inspections and assessments of the crane wheels. They can provide expert advice and perform specialized tests, such as wheel load tests, if required.

Remember to refer to the Asan Cranes!

Guidelines and any applicable industry standards or regulations for specific recommendations on controlling crane wheels. Regular maintenance and inspections contribute to the safe and reliable operation of the crane and help prolong the lifespan of the wheels.
