![]() The machine is also equipped with Caterpillar’s 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 are significantly reduced to a quiet 71dB. The 834K dozer features a completely redesigned operator station with automatic temperature control, a new touch-screen display with soft keypad, a electro/hydraulic parking brake, and a Cat Comfort III seat with air-ride suspension and integral controls, including steering transmission integrated control that allows convenient joystick steering. ![]() To reduce brake loads, an optional automatic retarding system maintains a set downhill speed, reducing brake use. This 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%t 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. The Cat 834K machine has a number of fuel-saving enhancements, including engine-idle-shutdown and engine-idle kick-down systems, and a delayed-engine-shutdown system that protects the engine from hot shutdowns. The C18 engine uses a field-proven Cat mechanically actuated, electronic unit-injection system for precise control of fuel delivery, yielding optimum performance and economy in all operating situations. This model was introduced in 2010 in a run of 1000 models.Rated at 496hp (370kW), 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. It is certainly highly recommended to anyone with an interest in historic Caterpillar machines. The features work well and the detail level is pleasing. This is another well executed model by CCM. It uses little plastic and the castings and paintwork are very good. The blade can be raised and lowered, and it offers a significant amount of tilt forward. The articulated steering performs well with an angle of around 30° to normal. The rear axle floats, and the wheel arches are pivoted so they can rise up if the wheel movement is significant. Rivets are painted and do not look obtrusive. The blade and linkages are metal with good anti-wear plates on the blade, and the CAT name is applied to a tab above the blade. ![]() There are counterweight slabs which look realistic, and the lift cylinder for the blade has plastic and rubber hydraulic lines. Behind the seat are a couple of holes which look as though they are for the attachment of a cab.ĭetail around the front axle is very good. The handrails are all metal and look fine. In the centre the operator's platform has a smooth surface, and the seat has slightly overlarge controls. The engine area is very good with a perforated radiator at the rear and a highly detailed plastic engine. The wheels are very good with chunky rubber tyres and good metal hubs. The detail is quite good underneath with the rear drive differential having bolt details, and a couple of painted screws attaching the blade frame are modelling compromises. There is no information about the real machine or the model, and there is no assembly required. There were no defects or missing parts on the review model. Inside, the model is wrapped in tissue and held between polystyrene trays. ![]() An outer cardboard box contains a presentation box wrapped in tissue. The packaging is to CCM's usual high standard. It weighed almost 40 tonnes and was sold throughout the 1960s. The Caterpillar 834 was introduced in 1963 and offered a wheeled dozer with an articulated frame.
