Key Considerations for Replacing Crane Wheel Assemblies

Proper functioning of crane wheel assemblies directly impacts operational stability and safety. When wear or damage occurs, timely replacement becomes essential. Below are critical steps for successful wheel assembly replacement.

1. Pre-Replacement Preparations

• Identify wheel type and specifications in advance
• Gather necessary tools: lifting screws, hydraulic jacks, and alignment instruments
• Power down the crane completely before starting work
• Secure the work area to prevent accidents

2. Removing Worn Wheel Assemblies

• Disconnect coupling bolts at the wheel shaft ends
• Loosen fastening bolts between the angular bearing housing and end beam
• Elevate the crane bridge using jacks, creating 10mm clearance between wheel treads and rail surface
• Carefully extract the old wheel assembly along the rail using pry bars

3. Installing New Wheel Assemblies

• Position the pre-assembled new wheels onto the crane rails
• Align the assembly near its mounting location
• Gradually lower the crane frame using controlled jack operation
• Insert and partially tighten all fastening bolts
• Replace gear couplings at both drive wheel ends simultaneously for balanced performance

4. Post-Installation Verification

• Confirm all fasteners reach specified torque values
• Check for horizontal/vertical wheel misalignment
• Test run the crane without load to verify smooth movement
• Make necessary adjustments if abnormal vibrations occur

Pro Tip: Always replace wheel assemblies in pairs to maintain symmetrical wear patterns.

Safety Reminder:

• Never attempt replacement without proper lockout/tagout procedures
• Use calibrated torque wrenches for final tightening
• Document replacement dates for maintenance records

For specialized wheel configurations, consult OEM technical specifications.
