Trailer Kingpin Repair: Saving Time and Money for Commercial Trucking Businesses

In the commercial trucking industry, where efficiency and cost management are crucial, maintaining the integrity of every component of your fleet is essential. One such critical component is the trailer kingpin. This vital part of a commercial truck’s coupling system ensures a secure connection between the tractor and the trailer, bearing the brunt of the load and enduring significant wear and tear. Mobalign’s expert trailer kingpin repair services offer a cost-effective and efficient solution, saving trucking businesses time and money. 

The Importance of Trailer Kingpin Maintenance

The trailer kingpin is pivotal to a commercial truck’s safety and performance. Over time, due to the constant pressure and friction, kingpins can wear down or become damaged. Regular inspection and maintenance are vital to prevent potential failures that could lead to costly breakdowns or accidents. Addressing kingpin wear promptly can extend the life of your equipment and ensure the safety of your drivers and cargo.

The Process of Trailer Kingpin Repair

Mobalign’s trailer kingpin repair process is designed to be thorough, efficient, and convenient.

Inspection and Diagnosis

Our technicians begin with a comprehensive inspection of the kingpin and surrounding components. We use precise measuring tools and a thorough process to assess the extent of wear of the pin and damage to the bolster plate to determine if a repair is possible.  

Precision Repair

If repair is possible, we employ specialized techniques to restore the kingpin to its original specifications. This involves re-machining the pin, and ensuring that all repairs meet industry standards for safety and durability.

To minimize downtime, Mobalign offers mobile, on-site repair services. Our team comes to your location, equipped with all the necessary equipment to perform the repair efficiently, saving you the hassle of transporting the trailer to a service center.
