Somerset, Pennsylvania-based J&J Truck Bodies & Trailers, a manufacturer of dump bodies, trailers, oil and gas equipment and custom transportation solutions, has announced the company has been awarded a patent for its horizontal ejection technology. Patent No. US 9,643,526 is designed for use in trucks treating snow and ice on roadways and in commercial paving applications.

Novel Feature

The J&J body, called the Horizontal Ejector (HE), incorporates an ejector ram, which is installed in the bed of the truck and eliminates the risks associated with overhead obstacles, reduces driver distraction, has a low center of gravity and prevents roll over’s that can occur from raising a dump body in unsafe conditions, according to the company. The HE features the J&J Dyna Control hydraulic system with AutoFeed, a hydraulic double-acting high lift gate tailgate and the J&J AWARE camera system. AutoFeed automatically moves the load forward when the spreader is low on material, allowing the operator to focus on plowing. The double acting tailgate allows for simple removal of frozen chunks of anti-skid in snow and ice applications. The J&J AWARE camera system allows operators to see the position and operation of the ejector inside the body and visibility behind the truck when operating in reverse.

Mike Riggs, senior vice president at J&J Truck Bodies & Trailers, says,
“We engaged numerous large state and municipal fleets in our market research, design and testing process and we are confident the patented technology will play a major role in future winter road maintenance and commercial paving. It’s a lower cost, easier-to-maintain solution compared to other conveyor/auger bodies currently on the market.”


J&J Truck Bodies & Trailers first introduced the HE truck body in 2016 at the North American Truck Equipment (NTEA) show in Indianapolis. Since then, the Pennsylvania Department of Transportation deployed a fleet of ejectors in early 2017 along with purchases by several other large municipal fleets, the company says. Founded in 1958, J&J Truck Bodies & Trailers is a division of Somerset Welding & Steel. The company also operates J&J Truck Equipment, both located in Somerset, Pennsylvania.
