User manual CATERPILLAR MD1003 BROCHURE

[. . . ] High-strength, abrasion-resistant steel in the scraper bowl minimizes wear. The rugged hitch, tongue, and structural design ensure long life in the toughest job site conditions. Designed to be pulled by Caterpillar® Track-Type Tractors or ChallengerTM Special Application Tractors, the Cat MD1003 Towed Scraper raises the standard. Scraper Bowl Unmatched Durability. High-Strength Bowl Design The scraper bowl is constructed using L-shaped box sections of high strength steel for superior strength and dent resistance. [. . . ] The floor is a box-section structure made from high-strength, abrasion-resistant steel for maximum strength during top loading and rigidity during intermittent push loading. High-strength, abrasion-resistant steel is used throughout the inside of the bowl for maximum wear resistance. Center Lift Design The center bowl lift design improves the strength and durability by placing the hydraulic cylinders between the tongue and spreader tube. This eliminates the need for draft arms, reduced weight and complexity. Cutting Edges Common Cat Wheel Tractor Scraper cutting edges and router bits are used to ensure exceptional performance and great availability. The center cutting edge is in the stinger (drop down) position for good penetration and efficient material flow into the bowl. When worn, the cutting edges can be rotated by 180 degrees, doubling the life. Ejector The ejector is constructed from a single plate of highstrength, abrasion-resistant steel. The ejector extends beyond the front edge of the scraper floor to minimize carryback. To minimize wear, the ejector weight is carried on steel rollers supported by a wear strip welded to the bowl floor. Cat XT ES hose works at half of the SAE's bend radius without sacrificing cold flex capability. As further protection, all exposed hydraulic lines are solidly secured with rubber-lined clamps, protecting the hoses from failures caused by rubbing. All hydraulic hoses and lines use O-Ring Face Seal (ORFS) fittings for maximum leak prevention. Steel Lines in Bowl Walls Brake lines and hydraulic lines for the rear scraper in tandem arrangements use steel lines inside the scraper bowl walls ­ eliminating hose damage caused by material in the bowl or during top loading. Cushion Hitch The optional cushion hitch adds two hydraulic accumulators to the scraper bowl lift circuit. When the operator activates the cushion hitch feature during transport, the accumulators allow the scraper bowl lift hydraulic cylinders to act as shock absorbers. The cushion hitch can be used in single scraper operations or by a lead scraper in tandem operations when pulled by a wheeled agricultural tractor. Hose Fittings Three hose fitting options are available: · · · 19 mm (3/4 in) poppet-style 13 mm (1/2 in) poppet-style Threaded flat-face connectors Easy-To-Use Connectors Threaded flat-face connectors, available exclusively on Cat Towed Scrapers, allow connection and disconnection under pressure and are less susceptible to wear caused by hose movement. 6 Customer Support · · · · Unmatched support makes the difference.
