Driving

The D5G has the power of proven turbocharged six-cylinder Caterpillar 3046T engine which delivers plenty of push. The power is smooth and responsive with excellent fuel economy and low noise emissions thanks to the turbocharger and high pressure fuel injection results. The CAT 3046T engine is designed for improved performance at lower engine speeds important for operators working in tight spaces at part throttle.

One thing I’m not a big fan of is the steering is proportionally controlled by the joystick position, but not the speed. Speed is not controlled by proportionally pushing the joystick further forward of backwards, but rather by two push buttons on the joy stick. You push one button to step up the speed, and the other to step it down. Each time you push the button it goes a little faster or a little slower. An indicator on the dash displays the machines current operating speed. When the joystick is moved to the neutral position, the tractor stops.

Maneuverability

The D5G easily maneuvers through side loading blade applications by engaging counterrotation briefly to correct machine position. Counterrotation also provides quick and easy maneuvering in confined work areas. The D5G has excellent tracking providing increased productivity on side slopes.

Construction

The Variable Pitch, Power Angle and Tilt (VPAT) blade has 14% increased capacity and is designed and built for versatility, durability and strength. The trunion is now mounted on the c-frame instead of the blade and the trunnion ball size has been increased to provide longer life and reduce ownership cost. The pin joints have also been improved to enhance durability and lengthen life. The mainframe has been modelled after larger Caterpillar tractors with a solid back bone for handling forces generated during tough dozing. Robotic welding process delivers reliability and durability need for construction sites.

Operator Station

The redesigned Operator Station is quieter and more spacious, based on the cab designs of the large Caterpillar track-type tractors. A new climate control system, increased leg room and enhanced visibility all enhance the ergonomics.

Other Cab comforts:
• Armrest adjustments
• Directed air vents
• Wide angle rear view mirror
• Cup-holder
• 12 volt power port
• Radio ready factory installed speaker and antennae
• Dome light
• Coat hook
• Tie down for lunch box
• Air conditioner

Visibility

The operator station provides an improved view of the blade and work site with 13% more glass area. The Angled doors on the left and right hand sides delivers improved visibility to the blade corners and edges. The operator can easily see blade corners and cutting edges so no more grading by feel.

Summary

The D5G combines the power of a larger tractor with the versatility and maneuverability of a smaller machine in meeting a wide range of job applications. Its comfortable operator station, excellent visibility and simple joystick control is everything you expect from Caterpillar.

D65EX-15EO Crawler Dozer

The GALEO brand is Komatsu’s lineup of advanced construction and mining equipment. Designed with high productivity, safety and environmental considerations in mind, these machines reflect Komatsu’s commitment to value, reliability and versatility.

Drive-Train

Featuring a turbocharged diesel engine with 153KW at 1950rpm which makes Komatsu superior for ripping and dozing operations. The direct fuel-injected engine with turbocharger ensures fuel efficiency while meeting Tier3 EPA emission standards and mounted to the mainframe with rubber cushions to minimise noise and vibration. The electronic power-train control improves reliability and smoother operation while maintaining optimal operational efficiency.

Steering and Travel Controller

The Hydrostatic Steering System delivers smooth, powerful turning powered by and independent hydraulic pump. When turning the outside track moves faster than the inside track resulting in smoother turning while not damaging the ground as the inside track is not locked. When load is applied and travel speed reduced the controller automatically downshifts to optimise the gear operation and fuel efficiency.

Console Interface

The palm controlled travel joystick delivers excellent control with a relaxed posture to reduce fatigue and the proportional pressure controlled blade joystick delivers fine control. Gear shifting is as simple as press of the thumb buttons. The seat has full 15 degree adjustment for ease of operator control during reversing and the console has travel control adjustment both for, aft and height as well as arm.

Maintenance

To ensure convenient maintenance the transmission, HSS and power train oil level gauge and tank are all on the right side of the dozer. A self-diagnosis function occurs when the machine is switched on and action codes are displayed on the console to alert the operator to abnormalities. A warning buzzer sounds for critical actions. The hydraulic piping for the blade is completely enclosed to ensure protection from damage and the modular power-train allows component to be mounted and dis-mounted without oil spillage.

Komatsu components are designed to work together for higher production and longer reliability. Building on almost 100 years of technology and expertise Komatsu provides exceptional technological innovation with reliability and value for money.
