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 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.

• 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. 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.

GOMACO’S SELECTIVE STEER CONTROLS

Featuring Steering Choices For Job-Site Mobility And Transportability On Four-Track Pavers

GOMACO’s Selective Steer Controls feature forward/reverse steer and manual steering choices. The G+ controls feature control dials for manual steering and travel. The paver can be turned left or right with the G+ control steering dial as it is moved in the manual travel mode.

GOMACO’S G+ CONTROL SYSTEM EASILY INTERFACES WITH STRINGLESS TECHNOLOGY

The G+ control system allows GOMACO’s slipform pavers, trimmers, and placer/spreaders to be controlled by an automated 3D machine control system and not by stringline. The 3D control system is adaptable to the G+ control system. This system can accommodate radii or superelevations automatically according to design data.

Real-time navigation systems allow the project data created in the CAD system to be directly put into the paving process. There is no stringline installation or maintenance. The stringless control systems can save you time and money.

BAR INSERTION SYSTEMS DESIGNED TO FIT YOUR PROJECT SPECIFICATIONS

GOMACO offers several bar insertion systems that are designed to accommodate your project specifications. Hydraulic cylinder, air-powered, and manual insertion are the three types of bar insertion. Bar inserters include the frame-mounted, sidemounted, 5400 series, and trailing form. GOMACO’s bar inserters provide easy and accurate bar placement to job specifications.

GOMACO OFFERS A PATENTED COMPUTERIZED TRANSITION ADJUSTER

The specialized GOMACO G+® accessory control system allows for programmed transitions from a crown to a flat cross slope in a superelevation, or vice versa. The G+ system is used to control the operations of up to four power transition adjusters (PTA), four tie bar inserters (TBI), two side bar inserters (SBI), a paint marker, and automatically timed spray bar.

GOMACO’S PTA, TBI, AND SBI

Unparalleled Accuracy with the GOMACO Power Transition Adjuster (PTA)

GOMACO’s hydraulically-powered transition adjuster (PTA) provides on-the-go transitions in the crown of the concrete slab. A switch in the operator’s console controls the PTA in a positive or negative (up or down) motion. This flattens the crown in the paving mold/slab or adjusts the crown back into the mold/slab. These transitions are necessary in paving through superelevations and intersections.

This simple solution provides an easy method for an operator to perform a smooth transition where necessary and accomplish the required slab profile as specified.

DETACHABLE AUGER/STRIKE-OFF FOR WIDTH CHANGES AND SHIPPING

The 5000 series paving mold with a detachable telescoping auger/strike-off gives contractors the benefit of a mold that can be either an open front or an auger/strike-off. The optional detachable telescoping auger/strike-off provides easy width changes with the removable and telescoping sections.

The auger/strike-off is independent and can be raised and lowered hydraulically. The strike-off features a center insert with a transition adjuster to allow for crowning.

Both the strike-off and auger have six feet (1.83 m) of telescoping capabilities to aid in changing paving widths. When paving widths need to be changed, the contractor only has to add or remove a section of the paving mold and then telescope the auger and strike-off in or out, depending on the needed width. The telescoping auger incorporates bolt-on flighting to accommodate the changing widths.

Along with giving the contractor some extra versatility on their pavers, the detachable telescoping auger/strike-off provides ease in transportation. The auger/strike-off can be detached from the front of the mold and the wings on the sideplates can be folded in to allow the paver, with the mold still mounted underneath it, to be transported under 12 feet (3.66 m) wide on one truck. This design is based on a 5000 series open-front mold, allowing such molds to be retrofitted in the field.

GOMACO’S SELECTIVE STEER CONTROLS

Featuring Steering Choices for Job-Site Mobility and Transportability on Four-Track Pavers

GOMACO’s Selective Steer Controls feature forward/reverse steer and manual steering choices. The G+ controls feature control dials for manual steering and travel. The paver can be turned left or right with the G+ control steering dial as it is moved in the manual travel mode.

DESIGNED FOR SAFETY

The GP-2600 is carefully designed to give years of dependable and safe service. The emergency stop buttons are on the operator’s console, and on corners of the machine, which are easily accessible from the ground level. Another safety feature is a backup alarm, which is designed to alert personnel around the machine when the tracks are set to operate in reverse. Other safety features include track guards, warning decals, an operator’s manual, and a safety manual. GOMACO machines are also designed to provide the operator with excellent visibility over the entire paving operation. GOMACO Corporation recommends the implementation of all safety procedures.

ONLY GOMACO OFFERS EXCLUSIVE “SMART” CYLINDERS FEATURING PUSH-BUTTON STEERING CONTROL SETUP

Only GOMACO offers “smart” steer cylinders to aid in the setup and operation of the four-track paver, especially in minimum-clearance projects. Steering control has been simplified with exclusive “smart” cylinders, used for dependable steering control feedback, eliminating the sprocket, chain, and potentiometer at the top of each leg. The “smart” cylinder reduces moving parts and eliminates the physical adjustments to the steering system. GOMACO’s exclusive operating system now makes it possible to have push-button steering setup. The “smart” cylinders can be taught the desired degree of leg rotation, so that the tracks do not strike any object in minimum-clearance requirements. The operator has the option of overriding this setting.
