This new design can be paired with Philippi-Hagenbuch's proprietary fluidic seal material to create a water-tight seal that contains liquid materials within an off-highway truck body or roll-off container when environmental regulations or local laws make even slight spillage undesirable.

Philippi-Hagenbuch showcased the Positive Seal Autogate tailgate at the 2019 AGG1 Academy & Expo.

The new Positive Seal Autogate tailgate can be designed for practically any size of off-highway truck or roll-off container. Paired with Philippi-Hagenbuch's simple yet robust outrigger, its traditional scissors-style mechanism provides an industry-leading maximum opening clearance at full dump. In the closed position, the new design positively locks into place and will not open under normal conditions without the body or container entering the ‘dump' mode.

The new design builds up the rearmost portion of the truck body or container to create a cohesive flange from which the tailgate compresses. Two hooks on either side of the base of the flange intercept a corresponding tag on the tailgate, allowing the tailgate to pivot inward as the sidearm and over-centre locking mechanism compressively lock the rear tailgate into place.

As with Philippi-Hagenbuch's entire line of Autogate tailgates, a three-year warranty is standard when installed with Philippi-Hagenbuch Installation Supervision Assistance or at the factory in Peoria, Illinois, US. Optional body seals, fluidic seals and cushion pads are available to further customise Philippi-Hagenbuch's Autogate tailgates.

When capacity is a concern, Philippi-Hagenbuch's Positive Seal Autogate tailgate can be built up for sideboards. Sideboards are available in 1in (2.5cm) increments from 6-40in (15.2-101.6cm) in height and provide a unified body height while increasing the volumetric capacity of the truck body, helping operators achieve optimal loads.
