Fast Tracking Speed - Saves Time and Money

Fast Job-Site Mobility

High-Production Slipforming

The track circuits on the three-track machine provide up to 49 fpm (15 mpm) operating speed for high-production paving and 125 fpm (38 mpm) travel speed, allowing quick and easy job-site mobility.

GOMACO’s Simultaneous Trimming and Pouring Design

GOMACO’s 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 10 ft. (3.05 m) wide. This means more production because the trimmer cuts only as wide as necessary and eliminates unnecessary backfill behind the pour. The trimmerhead has 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. 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 four-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.

Wide Variety of Stringline, Clamps, Rods and Sensor Line Accessories Available

GOMACO has a wide variety of stringline, clamps, rods, and sensor line accessories.

GOMACO sensor line is designed specifically for electronically controlled equipment. Sensor line and sensors provide the grade and steering information linked to the GOMACO operating system, located on the operator panel. The GOMACO electronic-over-hydraulic sensor system provides intelligent control of grade and steering for paving accuracy, and ease of operation.

Stringline stakes are made of high carbon steel, designed for a long life. Stakes are available in various lengths, ranging from 18 in. (457 mm) to 5 ft. (1.52 m). The stringline stakes range in diameter from 0.75 in. (19 mm) to 0.875 in. (22 mm).

One-piece and quick-set spring-action zinc-plated clamps are available.

The stringline zinc-plated, slotted rods are 18 in. (457 mm) in length and will accommodate a 0.125 in. (3 mm) diameter stringline.

GOMACO has many other sensor line accessories to choose from.

Sideshifting and Vertical-Lifting Trimmerhead, Mold and Hold-Down

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 slope to be applied to the curb and gutter 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.

Guillotine-Style and California-Style Curb Depressors Available for Driveways

Another feature on the Commander III is the optional hydraulically powered driveway blockouts, available for curb and gutter molds. This feature allows the Commander III to eliminate wasted material while slipforming through driveways.

The Guillotine-style curb depressor is hydraulically powered. It has a straight blade that enters the face of the curb while slipforming through driveways. The depressor can be changed to other molds if molds are slotted and clamped to accept the driveway cutout.

The California-style curb depressor is hydraulically powered. It has a curved blade that enters the face for use on curb and gutter molds while slipforming through driveways. The depressor graduates the curb in and out for the driveway, providing a smoother finish.

Advantages of All-Track Steering (ATS) and All-Track Positioning (ATP)

GOMACO Corporation sells more curb and gutter machines than anyone else in the world and we offer machines with all-track steer and machines with single-track steer.

Slipforming median barrier and bridge parapet are standard applications for the versatile GOMACO Commander III. Whether you are paving standard or variable barrier, the three-track system assures stability over grade variations. The Commander III will 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.

Paving Packages Add Versatility To Three-Track Commander

The Commander III, in the three-track mode, equipped with the versatile 12 ft. (3.66 m) paving package, will handle paving widths from 7 ft. to 12 ft. (2 m to 3.66 m) with minimum side clearance. The 16 ft. (5 m) paving package can accommodate widths from 7 ft. to 16 ft. (2 m to 5 m). The 16 ft. (5 m) paving assembly includes frame extensions for 12 ft. (3.66 m), 14 ft. (4.27 m) and 16 ft. (5 m) wide pours, and a left leg mount. GOMACO paving packages are an easy bolt-on attachment without major structural modifications required. The paving package kit also includes additional vibrator circuits, valves, switches and hydraulics to change from the standard machine to paving package set-up. Whether you choose the 12 ft. (3.66 m) or 16 ft. (5 m) paving package option, you can be assured it will fit all of your wider width slipform paving applications.

GOMACO’S Selective Steer Controls

featuring steering choices for job-site mobility and transportability

GOMACO’s Selective Steer Controls for the three-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.

Designed For Safety

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 operator’s manual, and a safety manual. GOMACO machines are also designed to provide the operator maximum visibility over the entire paving operation.
