CATERPILLAR’S D6K IS THE FIRST IN A NEW LINE OF CRAWLER DOZERS
Caterpillar’s D6K is the first in a new line of crawler dozers designed for top performance from first cut to finish grade. The D6K comes standard with a new hydrostatic drive train, durable SystemOne undercarriage, and seat-mounted electro-hydraulic controls ready for easy installation of the AccuGrade grade control system. For maximum productivity in tough applications, the D6K is equipped with the Caterpillar C6.6 engine with ACERT Technology. The engine produces 125 hp (93.2 kW) at the flywheel, the highest in its class size, the company reports. Constant net horsepower ensures peak engine power is available for the drive train and implements, even in high ambient temperatures. The dozer weighs 28,409 pounds (12 886 kg) with the XL (extended length) undercarriage and 29,690 pounds (13 467 kg) with the LGP (low ground pressure) undercarriage. The D6K features a new hydrostatic drive system that provides independent power and control of each track for precise maneuvering, quick acceleration, and fast on-the-go direction changes. The operator can command smooth power turns or even counter-rotation of the tracks by simply using the hydrostatic control located on the left armrest. Hydrostatic drive provides infinite speed selection from 0 to 6.2 mph (0 to 10 kph) in forward and reverse. The operator can program an independent forward and reverse speed and recall it with a simple press of a button. This lets the operator select the optimum speed for ground and job conditions. The D6K undercarriage features an oscillating track roller frame, which keeps more of the track on the ground in uneven terrain. The result is increased machine stability, decreased ground shock to the machine and a smoother, more comfortable ride. To further reduce operating costs and extend undercarriage life up to 70 percent, the Caterpillar SystemOne undercarriage is standard on the D6K. With SystemOne, each component has been designed to work together as a system to ensure balanced component wear and longer life. SystemOne eliminates accelerated wear on the bushings and sprockets when operating in reverse. As a result, cycle times can be reduced without sacrificing undercarriage life. A new, spacious operator station features seat mounted electro-hydraulic controls, combined deceleration / brake pedal, optional integrated AccuGrade display, reduced noise levels, and excellent visibility. A canopy configuration is available as well. The seat-mounted electro-hydraulic controls provide precise blade control, quick steering response, and comfortable operation. The left ergonomic joystick provides intuitive control of machine direction and speed. It also includes buttons for programming independent forward and reverse operating speeds and a thumbwheel for precise on-the-go speed adjustments. The right ergonomic joystick controls the dozer blade. It includes a button for automatic blade shake and a thumbwheel for precise blade angle adjustment. The D6K incorporates a single pedal that combines the functions of a deceleration pedal and service brakes. The operator can easily program the operation of the deceleration pedal to provide either variable engine speed or variable transmission speed. In either configuration, pressing the pedal past the speed control detent activates the service brakes. An on-demand cooling fan lowers operating sound levels and improves fuel economy.
