D3G^Non-Current

Advantages

Current earth moving and fine grading processes are labor intensive, dependent on manpower and instruments. Maintaining consistent grade between grade stakes is challenging, even for experienced operators. The AccuGrade Laser Grade Control System reduces labor requirements, aids operators in maintaining a consistent grade across the worksite and reduces material cost.

Simple Operation

The AccuGrade System consists of 4 basic components:
• Laser Transmitter
• Laser Receiver
• Electric Mast
• In-Cab Display

1) Laser Transmitter

An off-board laser transmitter (sold separately) emits a thin beam of light that rotates 360º, creating a grade reference over the work area. The transmitter is mounted on a tripod so the laser beam can rotate unobstructed above the tractor.

2) Laser Receivers

A digital laser receiver, mounted on a telescopic mast above the blade's cutting edge, is used to detect the laser beam. During grade set-up, with the cutting edge placed at finish elevation, the electric mast automatically positions the laser receiver to within 1.5 mm of the center of the laser beam. As the blade moves above or below finish grade elevation during the grading process, correction information is sent to the in-cab display. One receiver is required for single dimension control (lift) and two receivers are required for two-dimensional control (lift and tilt).

3) Electric Masts

Electric adjustable machine-mounted telescopic mast(s) are used for mounting the laser receiver(s) over the cutting edge, ensuring unobstructed laser reception. Powered by an electric motor, the operator can vertically raise and lower the mast(s) from inside the cab for precise positioning of the receiver(s)' elevation.

4) In-Cab Display

The in-cab display with easy to read grade indicator and backlit elevation display delivers all AccuGrade system information to the cab for easy viewing by the operator. The in-cab display arrows show the blade's position relative to grade and indicates cut or fill requirements of the work area. A built-in beeper provides audible tones to indicate grade errors and switch activation. Push button operation allows the operator to easily switch from manual mode for rough grading to automatic for fine grading.

Applications

The AccuGrade System is designed for a wide range of construction earthwork applications requiring tight tolerances and high production rates. The single laser system or dual laser system can be selected depending on the job requirements. The single laser system is ideal for fine grading sites with flat, single slope surfaces. The more versatile dual laser system is well matched for single or dual slope surfaces such as industrial, commercial and residential building sites.

Automatic Blade Control Feature

Automatic control of the blade's lift and/or tilt, depending on single or dual receiver system, provides consistent accuracy with higher productivity by reducing blade control demands on the operator. Based on correction signals, a hydraulic control valve automatically raises or lowers the blade cutting edge to maintain the correct blade cutting edge elevation. A single push button mounted on the blade control lever, allows the operator to easily switch from automatic to manual control for various work conditions.

Weatherproof Design

All components are designed rugged for dependable performance in harsh environments.

Redesigned Operator Station

Based on the cab designs of the large Caterpillar track-type tractors, the operator station has been redesigned to be more spacious. The new ergonomic layout emphasizes simplicity, ease of use and comfort. A new climate control system (HVAC), increased leg room and enhanced visibility allow the operator to focus on the job. With 13% more tinted glass area, the operator station provides a clear view to the blade and the surrounding work site.

Simpler Operation, Improved Control

We listened to our customers and designed the new G-Series machines with even simpler operation and improved control. This allows the operator to concentrate on more important aspects of the job such as blade control.

Joystick Control

The joystick control is easy to use. Speed, direction and steering are all controlled with the joystick. The result is easier operation and improved productivity. Ergonomic placement reduces operator effort and fatigue.

Speed and Direction

The joystick has three simple detented positions for travel: forward, reverse and neutral. A new feature is the capability to utilize faster reverse speed as a percentage of forward speed for increased productivity. Two joystick-mounted buttons are used to infinitely increase and decrease speed. An indicator on the dash displays the tractor's current operating speed setting. When the joystick is moved to the neutral position, the machine stops.

Steering

With the machine moving in forward or reverse, move the joystick to the left to turn the machine to the left; move the joystick to the right to turn right. The more the handle is moved to the right or left, the tighter the turn. Regardless of ground conditions, steering is consistent and predictable. Moving the joystick to the far right or left will make the tracks counterrotate for maneuvering in tight work areas.

Counterrotation

The D3G maneuvers easily through side loading blade applications. Simply engage counter- rotation briefly to correct machine position. Counterrotation also provides easy, quick maneuvering in small, confined work areas.

Tracking

The D3G has excellent tracking capabilities which increase productivity on side slopes.

Powerturn

Utilizing active effort of both tracks during a turn allows for more pushing power at the blade and less spillage of material from the blade.
