Chief’s new Heavy-Duty Rivet Gun puts out almost twice the force of the company’s standard rivet gun, enabling collision repair technicians to use it to install rivets in even the strongest steels, including Usibor®. The Heavy-Duty Rivet Gun is approved by Mercedes-Benz. “The new Chief Heavy-Duty Rivet Gun was developed to meet Mercedes-Benz specifications, including being able to pierce Usibor,” explains Mickey Swartz, director of global product management for Chief parent company Vehicle Service Group (VSG). “This is our strongest rivet gun, with a compression force of 22,000 lbs. vs. 12,000 lbs. available from our universal PNP90 rivet gun. While our universal rivet gun can be used on virtually any current automotive application, the Heavy-Duty Rivet Gun is designed for the next wave of vehicles that will incorporate even more high-strength steel.” The Chief Heavy-Duty Rivet Gun uses the same pneumatically driven hydraulic pump and pressure intensifier as Chief’s standard PNP90 rivet gun, but adds a few more built-in features. The Heavy-Duty Rivet Gun includes a retract feature and a dial to adjust the output working pressure. The mobile hydraulic tool not only outputs 10 metric tons of compressive force, it also gives 8 metric tons of tension force to hydraulically retract the punching tool from metal sheets at the push of a button. The dial provides infinite adjustment of the working pressure so the output force can be controlled to the desired level. With a small adapter set that reduces the output pressure, the Heavy-Duty Rivet Gun is backwards compatible to the PNP90, so shops that already have mandrels for the standard gun can use them with the Heavy-Duty version. The Heavy-Duty Rivet Gun can be used to install self-piercing or flow form rivets and to punch holes. Because the Heavy-Duty Rivet Gun is larger than the standard model in order to deliver higher power output, Chief is offering it with a cabinet equipped with a boom to help reduce technician strain and fatigue.
