GOMACO GP4 Slipform Paver

 

 

• The GOMACO GP4 is designed for paving up to 40 feet (12.19 m) wide and to accommodate multiple width changes. The GP4 is available as a two-track or four-track slipform paver.

• The exclusive G+® control system easily interfaces with stringline or 3D machine guidance to slipform all of your project needs.

• GOMACO’s GP4 two-track and four-track slipform pavers have dual-telescoping capabilities of up to seven feet (2.13 m) on each side of the paver, for a total of 14 feet (4.26 m) of automatic frame widening.

• Smart cylinders in the roller frame provide the width reference to the G+ controller and uses that information for steering setup and individual track speed control through radii.

• The four-track GP4’s smart leg positioning includes rotary-sensored slew drives on the pivot arms of each of the paver’s legs. The smart pivots on the legs provide the G+ control system with information on the pivot arm angle and works together with the track rotation sensors to maintain the tracks in the straight-ahead steering line.

• Rotary-sensored slew drives are also located on all four tracks for the ultimate in smart steering technology and extreme steering with the tracks having the ability to steer farther than ever before.

• The GOMACO four-track GP4 easily turns radii with smart leg positioning and smart track rotation.

• The GP4 slipform paver has been designed for easy transport.

• G+ allows quiet running technology with its ability to control the cooling fan speed based on temperature inputs from the engine and hydraulic oil. Based on these inputs, the cooling fan can run at a slower speed producing less noise. G+ load-sensed hydraulics provide maximum paving performance and optimized fuel efficiency.

• The GOMACO GP4 has an isolated operator’s platform for operator comfort during a long day of slipform paving.

• The optional GOMACO Navigator allows the paver's smart accessories to be easily monitored and controlled.

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.

 

GP4 G+ controls

The exclusive G+ control system on the GP4 slipform paver is easy to learn and operate.

 

 

 

GP4 operator

Safety and comfort is a priority with GOMACO equipment. The GP4 features an isolated platform for all day operator comfort along with full visibility of the paving operation and full control of the operator’s panel.

 

 

 

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 imperial or metric units. 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.

- Control from stringline, 2D, or 3D guidance.

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. The “run” screen includes leg position, paving speed and percentage of drive, steering, travel information, grade information, deviation meters, and many more features that can be used when slipform paving. 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 speed and total distance traveled. 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.

 

 

Transport Made Easy

The GP4 slipform paver is designed for easy transport. The operator can take the paver to the transport mode in minutes without assistance. The paver can be switched to the transport mode by simply rotating the legs to the transport position. After the legs are in the transport position, G+ travel is switched to “Transport” for complete control. A retractable, sliding console reduces the shipping width of the machine.

Smart Frame Widening

Smart Frame WideningG+ knows the width of the paver’s dual-telescoping frame. Changing the width of the slipform paver’s mainframe is accomplished with the Smart Cylinders and GOMACO roller frame.

The smart width provides easy, accurate width change setup and a reference for G+ to control proper steering and track speeds while turning a radius at varying widths of the paver.

 

 

 

 

Smart Leg Positioning and Smart Track SteeringSmart Leg Positioning

Pivot arms for the paver legs feature rotary-sensored slew drives. These smart pivots provide the G+ controls with information on the pivot arm angle, which coupled with the track rotation sensors, maintain the tracks in the straight-ahead line for steering, even when the leg pivot is at an angle.

 

 

 

Smart Track Steering

Track steering and rotation is accomplished with rotary-sensored slew drives. This smart track rotation provides the G+ controls with exact track location and position. Extreme steering is now possible with the tracks having the ability to steer farther than ever before.

Smart leg pivoting and smart track rotation now lets the G+ system automatically control the direction and speed of each individual track as it travels through a radius.
