[. . . ] A built-in timer allows 15 minutes of screed plate heating, preventing overheating of the plates. 4 Screed Plates Screed plates deliver a high-quality mat and a long service life. Screed plates are constructed of abrasion resistant alloy steel that resists damage and provides an enhanced service life. Quick screed replacement improves maintenance time. Curved nose bar design provides precompaction and enhances material flow under screed. [. . . ] Indicators show the percent of slope. Hydraulic System The extenders and vibrator systems are hydraulically controlled with electricover-hydraulic components. Systems are equipped with test ports for easy access to sample pressures. All hydraulic connections have O-ring face seal (ORFS) fittings and couplings to provide maximum protection against hydraulic system leaks. High-pressure Cat XT hoses provide an extended service life. Extender Configuration Two hydraulically driven extenders infinitely vary screed width within the paving range. The extenders are positioned in front of the main screed. The front-mounted extenders are supported by two 51 mm (2") diameter extendible tubes that provide torsional resistance and rigidity. Extender width changes can be made from the tractor, main screed or remotemounted control boxes. The remotemounted control boxes are positioned at the end of each extender. Extenders are equipped with vibrators and heaters that are separate from the main screed. Vibrator motors and shafts are hydraulically driven. Frequency and amplitude are synchronized with main screed vibrators. Crown Crown adjustment is made with an easyto-operate hand crank, which is equipped with a positive-locking device. Crown range is from +10% to -3% or +133 mm to -38 mm. Optional power crown control can be added. Electrical System Extender Height Height adjustment allows each extender to match the mat thickness being placed by the main screed. Adjustments are made with easy-to-operate hand cranks, which are equipped with positivelocking devices. Indicators show the amount of adjustment in 6. 4 mm (0. 25") increments. Optional power height controls can be added. 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 colorcoded wires with nylon-braided wrap to protect the electrical harness. Vibrator System The main screed and extenders are equipped with a vibrator system that provides initial compaction. Vibrator speed is adjustable from 0 to 50 Hz (3, 000 vpm). Pre-Strikeoff Shields A pair of patented pre-strikeoff shields are positioned at the front of the screed. The pre-strikeoff shields allow the proper amount of material to enter the area in front of the main screed, which influences the head of material in front of the main screed. The pre-strikeoff shields follow the leading edge of the main screed, when the thickness screws are used to adjust mat depth. [. . . ] This is also the time to look at dealer services that can be included in the cost of the machine to yield lower equipment owning and operating costs over the long run. More and more equipment buyers are planning for effective maintenance before buying equipment. Choose from the dealer's wide range of maintenance services at the time of purchase. Repair option programs guarantee the cost of repairs up front. [. . . ]
