GP3 Intelligent Slipform Paver

 

GOMACO GP3 Slipform Paver

 

 

The new GOMACO GP3 is designed for paving up to 30 feet (9.14 m) wide and to accommodate multiple width changes.

 

• The GP3 is available as a two-track or four-track slipform paver.

• GOMACO’s GP3 features a roller frame with dual-telescoping capabilities of up to seven feet (2.13 m) on each side of the paver, for a total of 14 feet (4.27 m) of automatic frame widening.

• The smart cylinders on the GP3 provide the width reference to the G+ controller and uses that information for steering setup and individual track speed control through radii.

• The GP3’s smart leg positioning includes rotary-sensored slew drives on the pivot arms of each of the paver’s four legs. The smart pivots on the legs provide the G+ control system with information on the angle of rotation and work together with the track rotation sensors to maintain the tracks in the straight-ahead line for steering.

• Rotary-sensored slew drives are also located on each of the slipform paver’s four tracks for the ultimate in smart steering technology and extreme steering with the tracks having the ability to rotate farther than ever before.

• The GOMACO GP3 easily turns radii with smart leg positioning and smart track rotation.

• The GP3 slipform paver has been designed for easy transport. The paver can be switched to the transport mode by simply driving the legs around to the transport position. The operator can take this paver to the transport mode in minutes without assistance.

• The slipform paver was designed to be easy to operate with the G+ control system. G+ allows quiet running technology and also load-sensed hydraulics for maximum paving performance and optimized fuel efficiency.

• G+ Connect™ allows all the smart accessories and guidance system for the GOMACO paver to be easily interfaced.

• GOMACO Remote Diagnostics (GRD) is so much more than telematics, giving owners the visibility of how, when, and where their equipment is being used.

• Load-sensed hydraulics for maximum performance and optimized for fuel efficiency.

• New hose and cable management features for hydraulic hose routing and frame cable organization.

• Retractable console to reduce shipping width.

• T-beam mounting rail incorporated into the telescoping frame.

• Isolated operator’s platform for operator comfort.

G+® Controls – Designed For Concrete Paving

It is now the technology that pulls everything together… G+ is the center that Connects all of the resources.

Once you experience G+ controls, you won’t be satisfied with anything else. It’s a control system that is both easy to learn and easy to operate. G+ expresses itself in easy to understand international icons and full script explanations. It operates in all the major languages of the world and in the imperial or the metric system. It has a lightning-fast processing speed and features two-way communications between the accessories and G+. Its instant digital feedback combined with the tight closed-loop electronic and hydraulic control creates a G+ experience that is smooth, efficient, and accurate. There is nothing on the market that can compare, because G+ is a proprietary system that was designed by our in-house control experts incorporating what we have learned from decades of experience in the field, and from what we have learned from you, our customer.

- Machine operation is simple.
- Machine response is fast.
- Troubleshooting is pinpointed, quick, and easy.
- Fault history available.

A flat-panel 6.5 inch (165 mm) anti-glare display screen is provided with sensor-controlled backlight levels for superior visibility in all operating conditions. The screen is rugged and shock resistant in its construction to protect against dust, moisture, and rain. G+ provides a full color display on the control panel to illustrate the various aspects of the paver for set up and operation. A “run” screen on the control panel illustrates the various aspects of the paver. It includes leg position, paving speed and percentage of drive, steering, travel information, grade information, deviation meters, and more. Newly designed icons and color graphics make it easy to understand and easy to identify the targeted functions. G+ receives a track speed reading from pulse pickups in the track motors to give you real time feet (meters) per minute and total linear footage (meters). G+ controls feature a detailed fault history with the time stamp, date, and information to track when each fault occurred. GOMACO’s G+ control system has been proven around the world.

 

 

 

The GOMACO GP3 is equipped with G+ controls and is slipforming a 25 foot (7.62 m) wide road with an integral curb on one side. The GP3 is also equipped with a 5400 series mold, 5400 series tie bar inserter (TBI), and a telescoping end sections for width changes.
