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 high-strength, 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. At the sides, alignment is maintained by Ultra High Molecular Weight (UHMW) plastic guides.Depth Indicator
A depth indicator is mounted on trailing scrapers to provide the operator a visual reference to scraper cut depth.
Tongue and Hitch
Rugged and Dependable.
Hitches for Cat® Tractors
Robust hitches are available for Cat® Track-Type Tractors and Challenger MTS800 / MTS900 Series Tractors. See your Caterpillar dealer for hitches for other pulling machines.Rugged Hitch
To prevent pin wear, the hitch uses a massive 89 mm (3.5 in) hitch pin securely held in place by eight bolts. The hitch platform, positioned between the pulling machine and the tongue, contains two pins that allow ± 45 degrees of side-to-side oscillation (roll), ± 90 degree turns (yaw), and ± 27 degrees of uphill/downhill movement (pitch). An integrated stop block allows a 90 degree turning radius while preventing contact between the tongue and the pulling machine tires/tracks. An adapter is available to quickly convert the scraper hitch for pulling drawn implements such as disk harrows and sheepsfoot compactor rollers.Robust, Straight-Line Design
Built from 13 mm (0.5 in) structural plate steel, the tongue is built to withstand the high drawbar forces imposed by track-type tractors pulling towed scrapers. The straight-line design eliminates draft arms, hydraulic cylinders, and lines located outside the width of the bowl, improving the overall strength to most effectively transfer the drawbar power to the cutting edges.Countersunk Tandem Hitch
A countersunk hitch is provided in the push block of lead scrapers, allowing the scraper to be push loaded when a second scraper is not used.
Lower the costs of Challenger™ Tractors in scraper applications.
Rubber Track Guides
Rubber Track Guides for Challenger MTS800 Series Tractors allow the rubber tracks to move and ride along roller wheels, but do not allow the track to move into the machine and causes expensive downtime. The track guides extend the service life of the belt as the side-loading on the belt guide blocks is reduced. Detracking is generally caused by sharp turns, usually under load. The rubber track guides can minimize tractor damage caused by detracking, but are not a replacement for sound operating techniques. Your Cat Dealer can provide training in proper towed scraper operation.Hydraulic Hose Hanging Tower Kit
The hydraulic hose hanging tower kit for Challenger MTS800 and MTS900 Series Tractors allows the hoses to move freely and eliminate entanglement while maintaining vertical alignment for reduced hose fitting and valve wear to increase service life.
Raising the Standards.
Standard heavy-duty, construction-grade brakes bring a new level of safety to the job site. Each machine is equipped with four calipers. Brake components are the same as were used on Cat Articulated Trucks.Standard Radial Tires
Standard radial tires reduce rolling resistance and provide excellent flotation and durability. Heavy-duty, five-piece rim ensure a long service life. Wheel hubs are oil filled and sealed with Cat Duo-Cone™ seals.
Tough components for tough applications.
Hose and Couplings
Cat XT™-3 ES (Enhanced Spiral) hose is used. Cat XT-3 ES hose has an exclusive cover which is formulated and manufactured by Caterpillar to provide up to 20 times more abrasion resistance than industry-standard hose. 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-styl
- 13 mm (1/2 in) poppet-styl
- Threaded flat-face 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.
Unmatched support makes the difference.
