Maintaining and Replacing Worn Track Rollers on Crawler Cranes: A Step-by-Step Guide
Jul 21,2023
As a construction engineer operating a crawler crane, it is essential to understand how to measure the size of track rollers and replace them when they become worn. Track rollers are critical components that support the crawler chassis and facilitate smooth movement. This step-by-step guide will provide you with the necessary instructions to accurately measure the size of track rollers and effectively replace worn ones, ensuring the optimal performance of your crawler crane.
Step 1: Safety Precautions:
Before beginning any maintenance task, prioritize safety. Ensure the crawler crane is on stable ground, engage the parking brake, and follow the manufacturer's guidelines for personal protective equipment (PPE), such as gloves and safety glasses.
Step 2: Identifying Worn Track Rollers:
Inspect the track rollers for signs of wear, including flattened or uneven surfaces, cracks, or excessive play. These are indications that replacement is necessary. Worn track rollers can compromise the stability and performance of the crawler crane, so timely replacement is critical.
Step 3: Measuring Track Roller Size:
To accurately measure the size of the track rollers, follow these steps:
- Use a caliper or measuring tape to measure the outer diameter of the roller.
- Measure the length or height of the roller.
- Note these measurements for reference when ordering replacement rollers. Ensure the replacement rollers match the original specifications to maintain the appropriate fit and functionality.

Step 4: Replacing Worn Track Rollers:
Once you have the replacement track rollers on hand, follow these steps to replace the worn ones:
- Erect the crawler crane on stable ground and extend the boom to its minimum length.
- Locate the track roller you wish to replace, typically accessible by removing the track shoe above it.
- Remove any bolts or fasteners securing the track roller assembly.
- Carefully slide out the worn track roller from its position.
- Clean the track roller mounting area to remove dirt and debris.
- Insert the new track roller, ensuring it aligns correctly with the track frame.
- Secure the new track roller assembly with the appropriate bolts or fasteners, following the manufacturer's torque specifications.
- Repeat the process for any other worn track rollers that require replacement.
Step 5: Post-Replacement Inspection:
After replacing the track rollers, conduct a thorough inspection to ensure proper installation and functionality:
- Verify that the new track rollers are securely attached and aligned.
- Check for smooth rotation without any binding or excessive play.
- Test the crawler crane's movement to ensure the track rollers are functioning correctly.
- Conduct a visual inspection of other surrounding components and track shoes for any signs of damage or wear that may require attention.
Regular maintenance and timely replacement of track rollers will help extend the lifespan of your crawler crane and minimize the risk of unexpected failures during construction operations.
