Kingpins wear and get damaged and that gets passed on to the fifth wheel, and then to other kingpins.
We stop that from happening and save our customers tens of thousands of dollars.
When a kingpin has excessive wear or gets damaged it can spread across the entire fleet. The wear and damage are passed from the kingpin to the fifth wheel, and then from the fifth wheel to the next kingpin. If ignored the problem can literally become a fleetwide issue that costs tens of thousands or even hundreds of thousands of dollars. We solve this problem for commercial fleets.
When Kingpin Specialists finishes with a kingpin, you can have complete confidence in your trailer connection. We back all our work with an industry leading warranty.
We are a BBB accredited company and as members of the Technology and Maintenance Council, the Colorado Motor Carriers Association, the Georgia Motor Trucking Association, and the Florida Trucking Association we work hard to support the trucking industry and promote safety and connection management best practices.
We train & certify our welders to national welding standards. Our technicians use a patented, portable lathe to ensure refurbished kingpins comply with the manufacturer’s operational specifications.
step 1 INSPECTION
Before a Kingpin can be refurbished it must pass a general inspection. The Upper Coupler/Grid assembly inspection is performed to ensure that there is no apparent structural damage. The pin is checked for squareness and proper height. The bolster plate thickness is measured ultrasonically and visually inspected for cracks and deformations. If the upper coupler does not meet the inspection criteria, then refurbishment is not recommended. When evaluating fleets our technicians will inspect multiple trailers on a single visit. The wear levels and structural assessment is noted on an inspection report that is provided to the fleet service manager.
This gauge is designed as an aid to determine the wear level and compliance of a Trailers Kingpin during routine inspections according to SAE J700 Surface Vehicle Standard and J2228 Surface Vehicle Recommended Practice.
Anytime you have metal in contact with metal you get wear and damage. The truck’s fifth wheel and the trailer’s kingpin are both composed of high strength steel. The more the connection between the truck and trailer is stressed the higher the wear rate. Most shops don’t have welders that are certified to complete a structural repair on a trailer therefore they ignore the kingpin and focus on the fifth wheel. This solves 50% of the problem, which is like solving 0% of the problem. If the KINGPIN is damaged or worn excessively it will not function properly and cause damage to the new or repaired fifth wheel when connected.
