HIGHLIGHTS

Xtreme Radii Capabilities

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.

Selective Steering

Stringline Steer Mode

This mode is selected when steering is to be controlled by the steering sensors. The controller automatically recognizes where the sensors are plugged in and assigns steering, slope, or dual stringline to the appropriate tracks and display meters. With the machine on line and in automatic steer, the operator walks the machine in reverse to the existing curb and gutter, utilizing the Reverse Steer feature. Then, flips the switch to forward steer to start slipforming.

Coordinated Steer

For minimum turning radius. When the steer select switch is in the “coordinated steer” position, the steering control dial will control the turning of the tracks. When the dial is in the center position, the tracks will be straight ahead. If the dial is turned left or right from the center position, the leading tracks will turn in the corresponding direction and the trailing tracks will turn in the opposite direction.

Crab Steer

Walk sideways for ease in putting the machine on line. When the steer select switch is in the “crab steer” position, the steering control dial will control the turning of the tracks. If the dial is turned left or right from the center position, all tracks will turn in the corresponding direction to walk the machine to the side.

Front Steer

When the steer select switch is in the “front steer” position and the steering control dial is turned left or right from the center position, the front tracks will turn in the corresponding direction and the rear tracks will remain straight.

Rear Steer

When the steer select switch is in the “rear steer” position and the steering control dial is turned left or right from the center position, the rear tracks will turn in the corresponding direction and the front tracks will remain straight.
