Commander III Brings A New Dimension To Paving

The GOMACO Commander III is recognized around the world as the elite multi-application slipform paver in the concrete construction industry.

Whether the job calls for curb and gutter, monolithic sidewalk and curb and gutter, recreational trail, barrier wall, bridge safety parapet, up to 20 ft. (6 m) wide paving or irrigation canal, no other paving machine in history has been capable of tackling more types of projects and satisfying more customers.

The list of applications continues to grow as contractors and GOMACO work in partnership on new innovations and attachments. The Commander III is the most job-proven slipform paver in the world with over 40 years of technology built in.

Multi-Application Four-Track Paver

• The Commander III four-track is a revolutionary concrete paver for slipforming up to 20 ft. (6 m) wide, and the four-track framework is designed with built-in versatility.

• The four-track is chosen for its job-proven results throughout the world. Multi-application capabilities include primary and secondary roads, highways, city streets, ramps and approaches, parking lots, alleys, shoulders, golf cart paths, recreational trails, and more.

• The four-track features the exclusive G21/G22 digital operating system that is simple to operate and understand. The system features self-diagnostics for grade and steering, cross-slope, and push-button steering setup.

• Minimum-clearance paving is achieved by using the high-drive track(s) or by removing one rear track for zero-clearance projects.

• The four-track machine features a frame that hydraulically telescopes on the left side up to 6 ft. (1.83 m). All four legs pivot so they can be positioned in different locations.

• Choosing the four-track design adds versatility with job-to-job mobility. Swinging the pivoting legs to the outboard position for travel, the machine remains mobile and easy loading is achieved with a minimum transport width of only 8 ft. 3 in. (2.51 m) and length of 29 ft. 0.7 in. (8.86 m).

GOMACO’s V2 Dual Mold System Provides Quick Width Changes

The versatile GOMACO V2 is an optional dual mold system that is hydraulically adjustable for paving at different widths. The V2 makes width changes fast and simple and will even make on-the-go width changes for tapered slabs.

The configuration of the front and rear molds dictates the minimum and maximum paving widths and the amount of total width variation. It features separate mold control for the left and right side.

It is also available with a curb profile on one or both sides for municipal paving.

The V2 sectionalized mold system includes a spreader-plow with hydraulic vertical movement to control the head of concrete in front of the mold. The plow telescopes with the machine framework to accommodate the width change.

The GOMACO V2 paving mold was developed to adapt to virtually any paver operating in the field today.

A Commander With Two Molds Attached For Super Quick Changes

This contractor saves time on the project by side-mounting a 14 ft. (4.3 m) mold to their Commander III for minimum-clearance paving, while keeping their 16 ft. (4.9 m) paving mold and kit underneath the paver. When they’re ready for wider width work again, the side-mounted package is removed and the contractor slipforms in the conventional paving mode.

GOMACO’S Selective Steer Controls

featuring steering choices for job-site mobility and transportability

GOMACO’s Selective Steer Controls for both the three-track and the four-track Commander III feature a forward/reverse steer switch and a position switch used to select the stringline steer mode or one of the other choices for manual track steering with the steering control dial.

		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.
