[. . . ] Page 5 Hydraulically-Driven Vibrators Hydraulically-driven vibrators located on the main screed and on the extenders provide pre-compaction. The vibrator speed can be easily adjusted to match mix type. Caterpillar® Dealer Support is the Leader in the Industry Caterpillar Dealers offer the very best dealer support, parts support and service training in the industry. 2 Electric Heat and Easy to Use Features Increase Operator Comfort The AS3251C Extend-A-MatTM asphalt screed with electrically-heated screed plates integrates an ergonomic control switch layout, and remote-mounted controls on the extenders. [. . . ] 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. Foldable Handles Dual-Bolt Guides False Wall Design 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. 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. Main Screed Controls Electric Heat Control Panel 5 Serviceability The CANbus electrical system and easy access to the screed plate adjusters enables quick service. 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. color-Coded Electrical Wiring Caterpillar® electrical harnesses utilize a kevlar braid and nylon mounting blocks to protect against abrasion. The wires are color-coded and numbered for fast reference. Advisor Display Screed Plate Adjusters Temperature Sensor Dimensions A B C D E F G Length with end gates (front to rear) Length without end gates (front to rear) Width with end gates (retracted) Width without end gates (retracted) Screed plate width (front to back) Height Walkway Width 2. Cutoff Shoe The cut-off shoe reduces the standard paving width from 2. Power Controls Standard power controls for crown, height and slope provide the operator with fingertip control. The crown adjustment is made with a switch in the right control panel. The height adjustment allows each extender to match the mat thickness being placed by the main screed. Each extender can be sloped during operation from 14% below horizontal to 2% above horizontal. Hydraulic System The extenders are hydraulically controlled with electric-over-hydraulic components. [. . . ] The spring-loaded design also creates a contained joint with the adjacent mat. electrical System The electrical system is 24-volts to match the tractor. Integrity of the electrical system on Cat® machines is ensured with the use of high-quality components. The Caterpillar electrical standards, developed to enhance reliability and durability, feature soldered, molded, numbered and color-coded wires with nylon-braided wrap to protect the electrical harness.
