Power Train Hydraulics Structures The 834H has a purpose built front frame for shocks and twisting forces that a wheel dozer will encounter in daily work. Structure improvements include larger diameter pin and bearings in the lower high hitch and high strength steel in the hitch bosses. 8 The 834H uses the Cat C18 engine The 834H uses electro-hydraulics for with ACERT® Technology that is ease of operation and operator comfort. The new Automatic Blade Positioning Smooth consistent shifting with fingertip helps to improve machine productivity. [. . . ] It mimics manual operations by automatically lowering the blade when the machine is shifted forward and raising it in reverse. The set points to where the blade raises/lowers can be easily adjusted from the operator's seat. Case Drain Filtration. The 834H has two case drain filters that protect the steering and fan pumps from contamination with easy access for service. 6 Load Sensing Steering. The STIC control system integrates the steering and transmission into a single controller. The steering system utilizes a variable displacement pump for maximum machine performance by directing power through the steering system only when needed. Caterpillar Monitoring System (EMS-III). EMS-III continually monitors various machine systems through three instrument clusters and provides a three-level warning system to alert the operator of immediate or pending problems. It shares information with the engine, hydraulic and transmission controls that can be used during servicing to simplify service and troubleshooting. The Caterpillar Monitoring System allows for new software to be uploaded in the cab. Demand Fan. The speed controlled, hydraulic demand fan provides maximum cooling efficiency by directing the appropriate amount of power through the fan system based on the coolant temperature. 7 Structures Advanced design and materials provide superior strength to the purpose built structures. Structure Construction. Combining the use of robotic welding on up to 90 percent of the 834H with castings used in several areas contributes to increased strength by helping spread the load and reducing the number of parts. This provides highly consistent welds with deep plate penetration and excellent plate fusion. The computer controlled machining ensures the alignment of pin bore, axle pad, cab mount and transmission/engine components. Box Section Engine End Frame Structures. 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 design provides maximum structural strength during dozing applications for improved stability. 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. Box-style sections in the hitch pins and crossmember assembly improve frame structure strength. A rubber isolation mount design reduces noise and vibration. 8 Blades Cat blades are available to match many dozing requirements. Universal Blade. The universal blade 3 3 (11. 1 m /14. 65 yd ) is designed to move large loads over long distances in mining applications. Cat blades are resilient, durable and designed with excellent dozing and rolling characteristics. · · Capacities and widths are set to achieve increased productivity. Spreading design allows for spreading of cover material, as well as dozing of heavier loads. [. . . ] Consider the financing options available as well as the day-to-day operating costs. 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. Cat dealers offer a variety of product support agreements and work with you to develop a plan that best meets specific needs. These plans can cover the entire machine, including work tools, to help protect your investment. [. . . ]
