• Achieve Xtreme Steering with the rotary-sensored slew drives, on each of the three tracks for extreme steering.

- The extreme steering capabilities, combined with the Commander IIIx’s sensored All-Track Steering (ATS) and sensored All-Track Positioning (ATP), make it the ultimate, intelligent slipform paver.

- The intelligent ATP on the Commander IIIx includes a smart hydraulic cylinder on all three legs. The smart cylinders allow G+® to know the position of all three tracks and can make steering adjustments as needed.


• The Commander IIIx can now pour Xtreme radii with ease.

- G+ individual track speed control provides smooth machine travel around a radius.

- The G+ control system easily operates on stringline or interfaces with the 3D guidance system for curb and gutter and tight radius applications.

- The Commander IIIx features the GOMACO three-sensor radius system for stringline. When paving with stringline, the lead steering wand is allowed to leave the stringline and reference is switched to sensor number two for traveling around the extreme radius.


• Xtreme Intelligence

- Intelligent offset is accomplished with smart hydraulic cylinders for telescoping the mold mounting system. This provides G+ the ability for repeatable mold offset. The trimmerhead and mold have independent vertical adjustments for raising and lowering.


• G+ Radius Software for stringline allows you to select the size of your radius and G+ calibrates and manages all aspects of traveling around the radius, including track angles and individual track speeds.

- G+ Radius Software for the control system allows the operator to select the size of the radius and input it into the controller. As the Commander IIIx approaches the radius, with the values programmed in, the operator activates the radius feature, and the curb and gutter machine slipforms around the radius. An operator can now pour a radius with ease using the G+ Radius Software.


• GOMACO Remote Diagnostics (GRD) is so much more than telematics, and is available for machine troubleshooting, diagnostic reviews, software updates, and more. GRD provides you with live information of how, where, and when your equipment is being used.

The GOMACO Commander IIIx, three-track, uses rotary-sensored slew drives on each track to slipform this curved curb and gutter on a residential street in Canada. This Commander IIIx is equipped with GOMACO Remote Diagnostics (GRD) to assist in fleet management through your cell phone or laptop computer.



Using 3D machine guidance, the Commander IIIx slipforms monolithic sidewalk and curb and gutter within a new subdivision.




The operator has a complete view of the paving operation, from the delivery of concrete to the finished product, while always maintaining full control with the pivoting operator’s panel.

The roller frame is an essential part of the Commander IIIx and provides easy and accurate width changes. The frame hydraulically telescopes on the left side up to six feet (1.83 m).





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.







The Commander III has a GBox on every leg to accommodate improved steering and grade with G+ controls. It’s part of GOMACO’s electronic and hydraulic initiative. GOMACO’s GBox features a new location for convenient access to the sensor bulkheads, valve overrides, and reduces hose and wiring needs. The GBox provides ease in serviceability, troubleshooting, and provides quick access with a horizontal swing door at ground level.








GOMACO Remote Diagnostics (GRD)

The Commander III can be equipped with GOMACO Remote Diagnostics (GRD). This software allows operators to see when, where, and how their machines are being used. Operators have the capability to request software updates from GOMACO in Ida Grove, Iowa, remotely without service personnel traveling to the job site. GRD allows for fleet management through GPS location and troubleshooting abilities.





Designed For Safety

The Commander IIIx 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.

Intelligent All-Track Positioning (ATP)

Intelligent ATP provides versatility in our slipform pavers. Each leg has a reinforced steel attachment plate that allows extra leg height adjustments. ATP provides the capability to perform various applications and work with differences in grade elevations and unique job-site logistics.




Extreme steering and G+ controls now allow the Commander IIIx to slipform tight radii. The tracks on the Commander IIIx can be turned to extreme angles, for getting on and off stringline and maneuvering around job-site obstacles.




The GOMACO Commander IIIx can be transformed from a three-track curb and gutter machine to a three-track slipform paver with an undermounted mold at a maximum of 15 feet (4.57 m) wide, by adding the parts designated in orange on the drawing above.




The four-track Commander IIIx is also available with rotory-sensored slew drives.
