Crawler Crane Track Shoe Breakage Solutions

Crawler cranes are robust machines used in various industries, but track shoe breakage can significantly impact their performance and productivity. Crawler crane track shoe, also known as crawler crane track pad, plays a vital role in supporting the crane’s weight and ensuring smooth movement. To avoid costly downtime and ensure operator safety, it is crucial to identify the causes of track pad breakage and implement effective preventive measures. In this blog, we will delve into the common factors behind track shoe breakage and provide comprehensive solutions to troubleshoot and prevent this issue. By prioritizing proactive maintenance practices, operator training, and collaboration with experts, you can optimize crawler crane operations and minimize track pad breakage.

the reason of crawler crane track shoe breakage

Track shoe breakage in crawler cranes can occur due to several reasons. Here are the main causes to be aware of:

Excessive Loading-the most key reason

Exceeding the rated capacity of a crawler crane is a significant cause of track shoe breakage. When a crane is overloaded, the track shoes bear a tremendous amount of stress and strain that they are not designed to handle. This can lead to accelerated wear, deformation, and ultimately, breakage of the track shoes.

There are various ways in which excessive loading can occur:

Ignoring Load Capacity Ratings

Each crawler crane has a specified load capacity determined by the manufacturer. This rating indicates the maximum weight the crane can safely lift and operate with. Ignoring or disregarding these load capacity limits can result in overloading the crane, putting excessive pressure on the track shoes.

Unbalanced or Uneven Loads

Improper distribution of weight on the crane can lead to uneven loading on the track shoes. Uneven loads put additional stress on specific areas of the track shoes, increasing the likelihood of breakage. It is essential to ensure that loads are evenly distributed and properly secured to prevent imbalanced loading.

Dynamic Loads

Dynamic or sudden loads, such as jerky movements or abrupt stops during crane operation, can create higher stress on the track shoes. These dynamic loads can exceed the track shoes' capacity and cause breakage. Smooth and controlled crane movements are crucial to minimize the impact of dynamic loads on the track shoes.

Other Main Reasons of track shoe breakage

Inadequate Track Tension

Improper track tension can accelerate wear and tear on the track pads, eventually causing breakage. Regularly checking and adjusting track tension as per manufacturer guidelines is crucial.

Neglected Maintenance

Poor maintenance practices, including insufficient cleaning, inspection, and lubrication of track shoes, can contribute to premature wear and increase the risk of breakage.

Challenging Terrain Conditions

Prolonged operation on uneven or abrasive terrains can subject the track shoes to excessive strain, potentially resulting in breakage. It is vital to consider ground conditions and take necessary precautions during operation.

Immediate Steps to Take After Track Shoe Breakage

Prompt action is necessary when crawler crane track shoe breakage occurs to prevent further damage and ensure operator safety. Here are the recommended steps to take:

first of all-Cease Operation

As soon as track pad breakage occurs, the first and most crucial step is to halt the operation of the crawler crane immediately. Continuing to operate the crane with a broken track shoe can lead to further damage and pose significant safety risks.

Second-Ensure Operator Safety

Prioritize the safety of the crane operator and surrounding personnel. If needed, evacuate the area and establish a safe zone until the situation is fully assessed and appropriate actions are taken.

thirdly-Thorough Inspection

Carefully examine the broken track shoe to identify the underlying cause, such as excessive wear, incorrect tension, or material defects.

Fourthly-Replace the Broken Track Shoe

To restore the crane’s functionality, the broken track pad needs to be replaced. Prepare a suitable spare track shoe that matches the specifications and standards provided by the manufacturer. Ensure proper installation by following the manufacturer’s guidelines and recommendations.

Finally-Report and Document

It is essential to report the track shoe breakage incident to the relevant authorities, such as the crane supervisor or maintenance personnel. Document the details of the incident, including the cause of the breakage, actions taken, and any repairs or replacements made. This information will be valuable for future reference and maintenance planning.

Proactive Maintenance to Prevent Track Shoe Breakage

To mitigate track shoe breakage, it is crucial to establish and follow preventive maintenance practices. When it comes to maintenance, there are two key aspects to consider: the track shoes themselves and the role of the crawler crane operator.

Crawler Crane Track shoes Maintenance

Track shoes, being critical components of the crawler crane undercarriage, require proper maintenance to ensure optimal performance and longevity. Here are some essential maintenance practices for track shoes:

Lubrication

Apply recommended lubricants to the track shoes at regular intervals to reduce friction and prevent premature wear.

Optimal Track Tension

Follow the manufacturer's guidelines for adjusting track tension to maintain proper performance and minimize wear.

Timely Replacement

Replace worn-out or damaged track shoes promptly to prevent further complications.

Crawler Crane Operator Training

Comprehensive training programs for crane operators are crucial to prevent track shoe breakage. Operators should be educated on the following areas:

Emphasize Load Limitations

Train operators to understand and adhere to the load limitations specified by the manufacturer. They should be aware of the maximum weight the crane can safely handle and understand the consequences of exceeding these limits, including potential crawler crane track shoe breakage.

Promote Smooth and Controlled Movements

Educate operators on the importance of smooth and controlled crane movements. Abrupt starts, stops, or jerky motions can exert excessive stress on the track shoes. Operators should be trained to operate the crane with precision and avoid sudden movements that can lead to track pad breakage.

Proper Training Programs

Provide comprehensive training programs to crane operators that cover not only the operation of the crane but also specific instructions on track shoe maintenance and care. Training should include understanding load capacities, proper load distribution, and safe operating practices to minimize stress on the track shoes.
