Avoid These Mistakes When Replacing Crawler Crane Lower Roller

Replacing crawler crane lower rollers which also known as track roller, is a critical maintenance task that requires attention to detail and adherence to proper procedures. However, certain mistakes can hinder the performance and safety of the crane if not avoided.In this blog, we will highlight five common mistakes to avoid when replacing crawler crane lower roller, along with the reasons why they should be avoided.

Mistake 1: Neglecting Safety Precautions

Safety should always be the top priority when working with heavy machinery like crawler cranes. Failing to follow safety measures can result in serious harm to the workers involved. 

How to do it right?

Personal Protective

Use appropriate PPE, including gloves, safety glasses, and steel-toe boots.

Gloves protect against sharp edges, safety glasses shield the eyes from debris, and steel-toe boots safeguard the feet from heavy objects and potential impacts.

Confirm Crane Status

Prior to replacing crawler crane lower rollers, it is crucial to prioritize safety by ensuring the crane is properly secured and stabilized. This involves selecting suitable outrigger pads, extending and engaging all outriggers, and using blocking and cribbing materials to prevent tipping or unwanted movement during the replacement process.

Follow safety guidelines

To ensure a safe replacement process for crawler crane lower rollers, it is imperative to follow all safety guidelines and procedures provided by the crane manufacturer and relevant safety regulations. Adhering to these guidelines minimizes the risk of accidents, maintains compliance, and promotes a secure working environment for all involved.

Comminicate with coworker

Coordination among team members is vital to ensure smooth workflow and prevent any conflicts or overlaps. This involves synchronizing activities, sharing resources, and planning the necessary logistics. For example, coordinating the availability of tools, equipment, and replacement components prevents delays or interruptions in the process.

Mistake 2: Skipping Proper Inspection

Neglecting to inspect the existing track roller, track links, and related components can lead to unforeseen issues. Hidden problems such as misalignment or underlying damage might be present, compromising the performance and longevity of the new lower rollers. A comprehensive inspection allows for timely identification and resolution of any issues, ensuring optimal crane functionality and preventing further damage down the line.

The proper inspection procedure

1 Visual Examination

Begin by visually inspecting the undercarriage system of the crawler crane. Look for signs of wear, damage, or misalignment in the track rollers, track links, and related components. Pay attention to any cracks, excessive wear, or deformities that may affect the performance or safety of the crane.

2 Check for Loose or Missing Bolts

nspect the bolts or pins that secure the lower rollers and track links. Ensure they are tight and properly fastened. Look for any missing or damaged bolts and replace them as necessary. Loose bolts can lead to misalignment or failure of the lower rollers.

3 Measure Roller Diameter and Tread Wear

Measure the diameter of the existing lower rollers using appropriate tools, such as calipers or a measuring tape. Compare the measurements with the manufacturer’s specifications to determine if the rollers are within acceptable limits. Additionally, assess the tread wear on the rollers. Excessive wear may indicate the need for replacement.

4 Check for Proper Lubrication

Evaluate the lubrication of the lower rollers and associated components. Ensure they are adequately lubricated to minimize friction and prevent premature wear. Inspect the seals and bearings for any signs of leakage or damage, as these can affect the performance and lifespan of the rollers.

Mistake 3: Failing to Prepare the Necessary Tools

Replacing crawler crane lower rollers necessitates specific tools and equipment to ensure a smooth replacement process. By failing to prepare the necessary tools, the replacement can be delayed or hindered, causing unnecessary downtime. 

the tool You Need To prepare before replacing lower roller

Wrenches

Wrenches, such as open-end wrenches or adjustable wrenches, are used to tighten and loosen bolts or nuts during the replacement process. They provide leverage and allow for secure fastening of components

Socket

Socket wrenches with various socket sizes are used to tighten or loosen bolts and nuts with greater ease and efficiency. They provide a secure grip and allow for quick and accurate adjustments.

Hydraulic Jack

Hydraulic jacks are used to lift and support heavy components during the replacement process. They provide controlled lifting and lowering, allowing for safe and efficient maneuvering of the lower rollers.

Lubrication Tools

Lubrication tools, such as grease guns or oil applicators, are needed to apply lubricants to the ltrack rollers and associated components. Proper lubrication ensures smooth operation and reduces friction, enhancing the lifespan and performance of the rollers.

Mistake 4: Attempting the Replacement Without Proper Training

Trying to replace the crawler crane lower rollers without the necessary training or expertise is a significant mistake. This complex task requires specialized knowledge and experience. Without proper training, there is an increased risk of making mistakes, causing accidents, or damaging the crane or its components. It is advisable to have individuals with the right training and expertise perform the replacement. If you lack the necessary training, contact the crane manufacturer or a qualified service technician for assistance. Working closely with professionals during the replacement process can enhance your knowledge and skills for future maintenance tasks.

Mistake 5: Never contact with your supplier

Neglecting to contact your supplier when replacing crawler crane lower rollers can lead to missed opportunities, delays, and potential complications. Maintaining communication and establishing a partnership with your supplier is crucial throughout the replacement process.

Your supplier serves as a valuable resource for parts availability. By reaching out to them early on, you can confirm the availability of the required track rollers and related components, ensuring they are in stock or can be obtained within the required timeframe.

Additionally, suppliers possess expert knowledge and can provide advice and guidance. They can assist with proper component selection, compatibility with your crane model, and any necessary modifications or adjustments.

Technical support is another advantage of contacting your supplier. If you encounter technical challenges during the replacement process, they can offer troubleshooting assistance, recommendations, and clarify any installation or maintenance queries.
