New for the 834K is a redesigned rear-axle trunnion, now wider and bolted directly to the frame rails, eliminating the previously used intermediate casting and allowing loads to be more effectively dispersed. Blade- mounting push beams have a "through-width" design, versus simply being attached to the sides of the frame, a design that dissipates the stress of blade corner-loading into a larger area of the frame. Heavy-duty steering cylinder mounts are designed to transfer and effectively dissipate steering loads into the frame. Reflecting the solid design of its predecessors, the new 834K retains its massive full-box-section rear frame that resists torsional shock and twisting forces. The system, with data-logging capability, features an Ethernet connection module and an integrated Cat Product Link telematics system, which transmits data to a secure web-based application (VisionLink™) for use by equipment managers. The 843K also is equipped with the Cat next-generation Vital Information Management System (VIMS™ 3G), which features a large touch-screen interface and easy-to-use navigation to keep operators informed of machine operating parameters. Interior sound levels also are significantly reduced to a quiet 71 dB(A). The 834K features a completely redesigned operator station, with automatic temperature control, new touch-screen display with soft keypad, electro/hydraulic parking brake, and the Cat Comfort III seat with air-ride suspension and integral controls-including the Steering Transmission Integrated Control (STIC) that allows convenient joystick steering. To reduce brake loads, an available automatic retarding system maintains a set downhill speed, minimizing brake use. The braking system can be equipped with auxiliary oil coolers for added protection. The 834K axles feature shaft-mounted, oil-cooled, multiple-disc brakes. The ICTC system reduces tire wear and permits full-throttle shifts for greater productivity. Forced-flow oil lubricates and cools the transmission high-torque clutches to ensure long component life.įor increased productivity and precise control, the impeller clutch torque converter (ICTC) allows the operator to adjust rimpull from 100 to 25 percent in order to match hydraulic effort and rimpull to the operating situation. The Cat 4F/3R planetary power-shift transmission used in the 834K features a new Advanced Productivity Electronic Control Shifting system, which is designed to provide greater machine momentum through shift points, enhancing performance and saving fuel. An on-demand, hydraulically driven cooling fan reduces horsepower draw for increased efficiency. Fuel-saving enhancements for the 834K include engine-idle-shutdown and engine-idle kick-down systems, and the delayed-engine-shutdown system protects the engine from hot shut-downs. The C18 uses the field proven Cat mechanically actuated, electronic unit-injection system for precise control of fuel delivery, yielding optimum performance and economy in all operating situations. Rated at 496 net horsepower (370 kW), the Cat C18 engine used in the 834K is available in three configurations to tailor the machine for any region of the world: Tier 4 Final (Stage IV) using a diesel particulate filter and a selective catalytic reduction system to control emissions Tier 3 equivalent without after-treatment and Tier 2 equivalent without after-treatment.
Available blade types include straight, universal, semi-universal and coal, ranging in capacity from 10.3 to 29.0 cubic yards (7.9 to 22.2 m³). The new 834K builds on the strengths of its predecessors with a completely new cab, drive train refinement, new monitoring and diagnostic features, new safety features and structural enhancements. The Cat® 834, introduced in the mid-1960s, has set the standard for wheel dozer design and performance for almost 50 years, ensuring customers optimum productivity, durability and availability through multiple life cycles. New Cat® 834K Wheel Dozer features new cab, refined transmission, advanced monitoring system and safety enhancements
