[. . . ] 825H Soil Compactor ® Engine Engine Model Gross Power Flywheel Power Weights Operating Weight Shipping Specifications Weight Cat® C15 with ACERT® Technology 299 kW 401 hp 264 kW 354 hp 32 734 kg 31 200 kg 72, 164 lb 68, 796 lb 825H Soil Compactor Representing a long-standing commitment to quality and performance, this rugged, powerful machine is designed and built for heavy-duty compaction and dozing operations. Power Train The 825H uses the Cat C15 diesel engine with ACERT® Technology which is U. S. Smooth, consistent shifting with fingertip control and electronic controls contribute to increased levels of productivity. 4 Hydraulics The 825H uses electro-hydraulics for ease of operation and operator comfort. 6 Tamping Wheels and Tips Tamping wheel tip design and modified chevron pattern offer greater traction, penetration and compaction for high soil compaction production. [. . . ] Equal compaction is forward or reverse is the result of the symmetrical tamping tip pattern. Tips are full perimeter and replaceable. The tip is welded to a base assembly, which then is welded directly to the drum. Cleaner Bars. Each wheel has two cleaner bars to keep the drums free of carryover dirt, regardless of rolling direction so efficiency is maximized. The adjustable cleaner bar tips are heat-treated and direct hardened, cutting edge steel to increase wear life, which translates into lower operating costs. 7 Structures Advanced design and materials provide superior strength to the purpose built structures. Structure Construction. Combines the use of robotic welding on up to 90 percent of the 825H, while castings are used in several areas to increase strength by helping to spread the loads and reduce the number of parts. This provides highly consistent welds with deep plate penetration and excellent plate fusion. The benefits are increased durability and fatigue strength. The computer controlled machining ensures the alignment of pin bore, axle pad, cab mount and transmission/engine components. Box Section Engine End Frame. Designed to resist twisting and torsional forces, the box section engine end frame provides a solid foundation for the axles, engine and transmission. The two-plate front frame provides maximum structural strength during compaction and dozing applications. The spread hitch design improves load distribution by reducing loads to the hitch bearings. The large center hitch design improves hydraulic line routing and makes service access easier. Upper and Lower Hitch Pins. The hitch pins pivot on double-tapered roller bearings. Box-style sections in the hitch pins and crossmember assembly improve frame structure strength. Increased diameter lower hitch pins add to the robust design. A rubber isolation mount design reduces noise and vibration. 8 Blades Multiple box-section construction with heat treated moldboard and DH-2 steel edges and end bits contribute to long blade life. Straight Blade. The straight blade is standard on the 825H. The S-Blade features multiple box-section construction, including heat treated moldboard and DH-2 steel cutting edges and engine bits for long life. The outside mounting is a stronger design because stresses are put on the frame rather than the blade so blade flexing is reduced. It also allows for higher lift and a wider blade can be used than with an inside mounted design. Air suspension adds to the overall comfort level by smoothing the ride over rough terrain. [. . . ] You receive the same warranty and reliability as new products at cost savings of 40 to 70 percent. Improving operating techniques can boost your profits. Your Cat dealer has training video tapes, literature, application and equipment training courses and other ideas to help you increase productivity. Maintenance Services. More equipment buyers are planning for effective maintenance before buying equipment. [. . . ]
