The unique line of Philippi-Hagenbuch Autogate® Tailgates is designed specifically as an avenue to maximize haul truck utilization, effectively increasing haul capacities by up to 20 percent while also providing added safety and extended tire life. Philippi-Hagenbuch’s tailgates include models suited for both articulated and rigid frame trucks, making them the ideal solution for everything from quarries to coal mines and even mineral mining applications. The increased volume capacity proves effective for any material – hard and rocky or liquid.
Continuing its longstanding tradition of providing productivity-enhancing products to the aggregate and mining industry, Philippi-Hagenbuch designed the Autogate Tailgates as a solution for maximizing the truck’s volumetric capacity while reducing spillage. Unwilling to subscribe to the traditional one size fits all approach of other tailgate manufacturers, Philippi-Hagenbuch constructs the Autogate series with a specific spec for each model and make of both articulated and rigid frame trucks. This tailored approach serves to not only eliminate spillage from the rear of the bed, but also prevents side spillage – even when driving on inclines or making sharp turns. By blending the unique design and customized fit with the specific truck requirements, such as increased height clearance or enhanced capacity, the PHIL Autogate Tailgates flow with the overall truck design to enhance capacity while also ensuring balanced load distribution for easy maneuvering and enhanced safety.  
Extending beyond simply increasing capacities, the PHIL Autogate Tailgates offer the added benefit of longer tire life and reduced maintenance by increasing the load target and providing a more centered and evenly distributed load. This optimized balance of the load further enhances safety while driving in adverse or uneven terrain. Operating without a tailgate often results in front-loading of the trucks, which causes added weight and stress on the front tires, significantly accelerating wear. In addition, materials are prone to falling off the rear of a truck not equipped with a tailgate, resulting in added risk of puncturing tires or creating additional work for haul road graders maintaining the passage in and out of the quarry or mine.
With a keen focus on engineering products with a simple design to reduce maintenance and failures, Philippi-Hagenbuch manufactures the Autogate Tailgates to stand up to years of job site and environmental abuse. Constructed of high-strength steel and an exclusive steel alloy chain, the PHIL Autogate Tailgates boast maximum durability with virtually no maintenance in a design durable enough to handle even large boulders. Philippi-Hagenbuch’s unique approach uses no locks, cylinders, grease points or controls – virtually eliminating the potential of malfunction. As the body dumps, gravity naturally opens the tailgate to discharge material from the bed in a design that eliminates traditional maintenance headaches. Autogate Tailgates provide maximum opening at the exact angle where material begins to move, ensuring optimized dumping speed.
The Autogate Tailgates are customized to fit nearly any scope and size of articulated or rigid frame off-highway haul truck and can be installed through the OEM or retrofitted on-site. The three-piece tailgate construction allows for easily adapting to different bed widths, ensuring hassle free installation.
