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 speed and total distance traveled. G+ controls feature a detailed fault history with a time stamp, date, and information to track when each fault occurred. GOMACO’s G+ control system has been proven around the world.
This GOMACO four-track GP3 is equipped with two 5400 series bar inserters to slipform this interstate project. The 5400 series bar inserter is rear loading for quick and easy accessibility.
The GOMACO four-track GP3 is equipped with a 27 foot (8.23 m) folding conveyor to slipform the variable barrier. The mounted conveyor feeds concrete into the mold’s hopper to deliver a consistent flow of concrete into the barrier mold.
A telescoping spreader plow on front of the paver spreads the concrete evenly ahead of the mold. Its telescoping ability also allows for easy width changes.
Outriggers can be added to the two-track GP3 for transport loading and frame widening. With the addition of the outriggers, the GP3 can be raised and a truck trailer can be backed underneath the machine.
A special front mounted conveyor was added to this two-track GP3 for concrete placement. The ready-mix trucks were not able to get in front of the machine because of the steel rebar grid laid out on the grade, so the conveyor was added and the trucks discharged the concrete from the left side of the paver.
Equipped with 3D machine guidance along with two paver-mounted GSI (GOMACO Smoothness Indicator) units, this GOMACO GP3 slipforms a 15 foot (4.57 m) wide section of highway.
This GP3 slipforms a 12 foot (3.66 m) wide truck apron with an eight inch (203 mm) high curb on the inside of a roundabout. The G+ control system allows the GP3 to maintain proper inside and outside track speeds through the radius.
Minimum clearance is achieved when the GP3 is turned to transport mode with a sidemounted mold to slipform a 12 foot (3.66 m) section of interstate.
The GP3 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.
G+ knows the width of its 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.
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.
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.
The GP3 is carefully designed to give years of dependable and safe service. The emergency stop buttons are on the operator’s console and on the corners of the machine, which are easily accessible from the ground level. The machine is equipped with 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, operator horn, 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.

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.
5400 Series Bar Inserter
The 5400 series bar inserter is front or rear loading and front inserting for ease of use. It mounts to the mold's T-bar and allows on-the-go crown changes, while maintaining a constant depth. The bar box is mounted to the paver's rear T-beam mounting rail for easy access and loading of the bar magazine. There are individual depth guides on the right and the left side of the bar inserter in order to keep bars parallel to the top of slab. The 5400 series bar inserter can hold up to 50 bars in the bar magazine and bar loading chain system.
The trailing form with manual, air-powered, or hydraulic bar insertion is designed to trail the track on two-track pavers. This system will accommodate most types of bars.
The hydraulic system includes vibration to the bar, and is designed for large bars. Vibration is applied to the bar during insertion, which provides consolidation of concrete around the bars. This system requires one vibrator circuit. The minimum slab depth required is six inches (152 mm) and the maximum bar length is 48 inches (1219 mm).
The four-track paver’s hydraulic powered bar inserter is located in front of the rear paver leg at the end of the mold.
The GOMACO four-track GP3 is equipped with an IDBI attachment. The IDBI is an independent attachment that is self-contained, self-powered, and can insert transverse dowel bars into the pavement.
Trailing Form and Bar Inserter
The trailing form and manual bar inserter is designed to trail the track on a two-track paver. This system will accommodate most types of bars.

• The GSI (GOMACO Smoothness Indicator) screen on the Navigator allows ground personnel to monitor paving smoothness for up to four GSI traces (two visible at a time) using either a real-time localized roughness graph or a simulated California profilograph.
• The machine speed is now logged, which makes it possible to relate the machine speed with the smoothness, as well as automatically track the machine's start and stop events.
The Navigator’s GSI trace screen showing the simulated California Profilograph graph.
• The ACC (Accessories) tab on the Navigator will allow ground personnel to monitor the pave time operation of the tie bar inserter (TBI), side bar inserter (SBI), and power transition adjuster (PTA).
• The Navigator supports up to four PTAs. To transition the PTAs, simply enter the new target height values for each PTA, enter the transition distance, and press start transition. The yellow line represents the current height of each PTA, and the red line represents the target height for each PTA.
• Four TBIs and two SBIs are supported on the Navigator. The machine position in the current dowel bar spacings is indicated by the red vertical line that will travel across the screen when the machine is moving. When the paver (red line) passes a TBI/SBI fire position, the fire lamps are illuminated.
ACC (Accessories) Screen shows how many PTAs, TBIs, and SBIs are set up on the paver, and the distance between them.
The SBI and TBI setup allows personnel to adjust the number of bars to be inserted and the distance between each bar. Simply set the DBI space, number of bars desired, and the bar spacings are calculated automatically.
• GSI (GOMACO Smoothness Indicator) utilizes compact and ruggedized CAN-based sonic sensors and a CAN-based digital slope sensor to read the smoothness profile anywhere on the slab’s surface.
• The GSI is mounted on lightweight aluminum to allow for easy handling and assembly and less maintenance.
• The lower profile mounting system allows the work bridge to be mounted directly above the GSI, if needed.
• A new mounting system places the GSI units evenly across the back of the paver for accurate measuring.
• Each GSI mount features a digital color LCD screen on each tracer bar providing digital diagnostics right at the sensor location.
• The optional Navigator's GSI screen provides a full diagnostics platform incorporating the GSI traces, bar insertion locations, transition adjusters, and G+ control in one location and on ground level.
Thanks to the redesigned lower-profile mounting system, the work bridge can be placed over top of the GSI tracing units.
