Helping You To

Squeeze Every Ounce of Payload

Philippi-Hagenbuch, Inc. started with an idea for a simple product - a tailgate for off-highway haul trucks. After retiring from a global off-highway truck manufacturer, L.B. Philippi partnered with his son-in-law LeRoy Hagenbuch to design, engineer, sell and fabricate the world's first commercially available tailgate, which became known as our Autogate Tailgate.

To date, PHIL has designed and built tailgates for just about every make and model of off-highway haul truck on earth. With over 20,000 installed, PHIL has become the global leader in off-highway haul truck customizations. When you're ready to squeeze every last ounce of payload out of your fleet, we're here for you.
