The Commander III Brings A New Dimension To Paving

Commander III Three-Track

GOMACO's Patented Simultaneous Trimming and Pouring Design

GOMACO's patented trim/pour design assures maximum concrete yield. The Commander III is equipped with a 42 in. (1067 mm) wide sectionalized trimmerhead. Extensions are available on the unique sectionalized trimmerhead for trimming up to 120 in. (3048 mm) wide. This means more production because the trimmer cuts only as wide as necessary and eliminates unnecessary backfill behind the pour. The trimmerhead has a 36 in. (914 mm) hydraulic sideshift, 18 in. (457 mm) of hydraulic vertical adjustment and an extra 6 in. (152 mm) of manual vertical adjustment.

Fast Concrete Loading Provides Increased Production

The charging conveyor on the Commander III provides fast concrete loading which increases production. The conveyor is hydraulically powered and reversible, with a charging hopper. The charging conveyor is 24 in. (610 mm) wide and 17 ft. 1 in. (5.21 m) long between pulley centers. The belt speed is variable up to 320 fpm (97.54 mpm). The 4-way pivoting conveyor mount provides hydraulic positioning (slide and tilt) for negotiating discharge from the ready-mix trucks and grade variations. The belt wiper features segmented blades mounted on individual cushions. This allows the cleaning tips to conform to the center of the belt for continuous contact without the need for constant adjustment.

Travel speed on the Commander has nearly doubled. The track circuits on the three-track machine now provide up to 44 fpm (13 mpm) operating speed for high-production paving and 97 fpm (30 mpm) travel speed, allowing quick and easy job-site mobility. The four-track Commander has an operating speed of 33 fpm (10 mpm) and auxiliary up to 73 fpm (22 mpm).

The Commander III features the sideshifting and vertical-lifting trimmerhead, mold drawbar and hold-down assembly. The mounts on the Commander III provide up to 36 in. (914 mm) hydraulic sideshift, 18 in. (457 mm) of hydraulic vertical adjustment and 6 in. (152 mm) of manual vertical adjustment. This enables the trimmerhead and mold to be raised or shifted to clear obstacles. The versatility of the trimmer, mold, and the rolling hydraulic hold-down allows sloped paving applications while the machine remains level, thereby retaining stability. The hold-down assembly, with limiting rods, allows compensated pressure to be applied to the rear of the mold to control uplifting. The mold is designed to allow for side-to-side movement for radius work.

State-Of-The-Art Design With The Exclusive "Smart" Cylinders

Slipforming median barrier and bridge parapet are standard applications for the versatile Commander III. Whether you are paving standard or variable barrier, the three-track and four-track system assures stability over grade variations. The Commander III hydraulically elevates to slipform barrier or parapet without modifications. Minimum-clearance requirements are easily achieved with the side-mounted mold. The mold can be center-mounted to allow working in a 10 ft. (3.05 m) wide area. The Commander III four-track paver in the barrier mode (transport mode) is the choice for slipforming tall wall or variable barrier.

Commander III Four-Track Barrier Package

Four-Track Versatility For Barrier and Parapet

• 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 rideability results throughout the world. Multi-application capabilities include airport runways, 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 digital operating system that is simple to operate and understand. The G21 features self-diagnostics for grade and steering cross-slope and selective steer controls for paving accuracy and ease of operation.
• All-Track Steer (ATS) and All-Track Positioning (ATP) are features that provide contractors with a versatile machine. The advantages to ATS and ATP are maneuvering around obstacles, avoiding obstacles, set-up time, mounting molds, transporting the machine, and loading and unloading.
• Minimum-clearance paving is achieved by using the high-drive track(s) or by removing one rear track for zero-clearance projects.
• 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 transport width of only 8 ft. 3 in. (2.51 m) and length of 29 ft. 3 in. (8.92 m).
• The four-track Commander III can utilize the GOMACO Auto-Float^® for the final finish to a flat slab.

Commander III Four-Track

Three-Track Commander Transforms to a Four-Track Paver

The three-track Commander prime mover drives over the supported four-track frame. The left end car has been removed from the frame to allow the rear leg of the Commander to move through the framework.

The Commander is attached to the four-track frame. The pivoting left front mount is removed. The three-track assemblies (leg and track) are utilized for the four-track paving mode. The left front track assembly (Track #1) on the Commander is positioned as the left front on the four-track frame. The right front track assembly (Track #2) on the Commander is positioned as the right front on the four-track frame. The rear track assembly (Track #3) on the Commander is positioned as the right rear on the four-track frame. Location of steering cylinder on the track assembly dictates its positioning in the transformation.

The end car on the four-track frame is attached, and the left front track assembly from the Commander is attached. The additional fourth track assembly is attached to the left rear of the frame. The four-track paver drives over the paving mold for quick attachment.

The Commander III is carefully designed to give years of dependable and safe service. Emergency stop buttons are located on strategic areas of the machine. The E-Stops are on the operator's console and on corners of the machine or can be positioned at various points on the machine providing optimal use for specific applications. Other safety features include track guards, warning decals, an operators manual, and a safety manual. GOMACO machines are also designed to provide the operator maximum visibility over the entire paving operation.

Molded Fiberglass Shroud and Console Cover Provides Easy Access and Serviceability

The engine shroud and console cover are now molded fiberglass with gas shocks for easy access to all service areas. The Commander III has expanded capability for more horsepower and choice of John Deere and Caterpillar engines with up to 200 hp (149.2 kW).
