Benefits & Features

Rear-Mounted Extenders The extenders are mounted behind the main screed. This rearward location allows material to easily flow back to the extender when increasing paving widths. Heavy-Duty Support Design Two heavy-duty support tubes and a third frame member stabilize the extender and prevents flexing for even material flow. Extender-Mounted Controls The extenders include controls for adjusting paving width, material flow and tow-point height, convenient features when setting-up for wide width paving. Integrated Harnesses The electrical connections for the sonic feeder control sensors are integrated within the screed frame, eliminating the extra cord leading to the tractor. Rear-Mounted Extenders Heavy-duty supports provide torsional rigidity that allows even material flow, resulting in high quality mats. » Learn More Screed Plates The screed plates are constructed of an abrasion resistant alloy steel and utilize curved nose-bars to provide pre-compaction and good material flow. Hydraulically Driven Vibrators Hydraulically driven vibrators mounted on the main screed and extenders increase mix density under the screed. Electric Heating Elements The heating elements are located in each screed plate section to provide even heat distribution. The heating elements are reusable and can be easily removed and installed on new screed plates. Uniform Heating The heating elements provide uniform heat distribution over the entire screed plate for reliable operation. Screed Plates The industry-leading electric heating system delivers tight textures for high-quality mats and a long service life. » Learn More Spring-Loaded End Gates The spring-loaded end gates create a downward force that cause the gates to follow the profile of the surface being paved, ensuring a good joint with the adjacent mat. False-Wall Design The false-wall design reduces mix contact with the sliding portion of the gate, providing easy gate adjustments. Bolt-on Design The bolt-on design allows easy end gate installation and removal when transportation concerns exist. Foldable Handles Foldable handles located on the end gate height adjustments allow them to be fully retracted when working close to barriers. Dual-Bolt Guides The dual-bolt guides allow smooth vertical movements and eliminate retention chains. End Gates Easy-grip handles and dual-bolt guides provide smooth height adjustments to ensure good joint-matching capabilities. » Learn More Conveniently Located Controls The screed controls are conveniently located and easily recognizable to provide efficient operation. Quick Angle of Attack Adjustment The thickness control screws utilize spinner handles for easy angle of attack adjustments. Electric Heat Control Panel The electric heat control panel includes three temperature settings that are able to accommodate a variety of asphalt mixes and paving conditions. Electric Heat Controller An electric heat controller automatically regulates screed plate temperatures to the selected setting. The controller also assists troubleshooting procedures with minimal training. Control Panels A state-of-the-art electric heating system with controls that are located in the right place, allow the operator to make quick adjustments. » Learn More Quick Screed Plate Adjustment The threaded-bolt design located on the front and rear edge of the screed plates eliminate shims to provide quick replacement and leveling. CANbus Electrical System The CANbus electrical system utilizes a controller to perform screed functions, eliminating many wires and relays for a reliable electrical system. CANbus Interface The CANbus electrical system on the screed provides an interface with the Advisor display on the tractor for simplified diagnostics. The system is compatible with Cat ET. Color-Coded Electrical Wiring Cat® electrical harnesses utilize a kevlar braid and nylon mounting blocks to protect against abrasion. The wires are color-coded and numbered for fast reference. Serviceability The CANbus electrical system and easy access to the screed plate adjusters enables quick service. » Learn More
