GOMACO GT-3200 50FPM Concrete Curb Gutter Slipform Machine

Complete Curb and Gutter Projects 50% Faster with Zero Rework

The GOMACO GT-3200 delivers precise curb and gutter slipforming at a maximum paving speed of 50 feet per minute (15.2 mpm), eliminating the need for manual trimming and dramatically reducing project completion time. This curb and gutter machine bridges the gap between smaller equipment and heavy barrier pavers, giving contractors professional-quality results without the frustrations of slow production, inconsistent profiles, or excessive hand finishing.

Why Contractors Choose the GT-3200 50FPM

• Doubles Production Speed – With slipforming at up to 50 feet per minute, the GT-3200 curb and gutter machine eliminates the waiting that comes with slower, traditional methods. Projects that once took days can be complete in a fraction of the time.

• Cuts Labor Costs – Fewer crew members are required compared to hand forming. The machine's precision means minimal rework, so people spend less time correcting mistakes and more time moving to the next site.

• Delivers Consistent Quality – Precise slipforming with hydraulic vibrators and the G+ control system produces uniform curb and gutter profiles every pass, eliminating the inconsistencies of manual work.

• Built for Durability – Powered by a 91 hp (67.9 kW) Tier III Caterpillar diesel engine, the GT-3200 is engineered for demanding commercial and municipal projects where reliability matters most.

• Simple Operation – The G+ control system allows operators to learn the interface quickly. The operator's platform offers excellent visibility over the paving operation, so every operator has an excellent view of the work at all times.

What Makes It Different

Most curb machines force contractors to choose between speed and precision. The GOMACO GT-3200 is built differently, delivering both without compromise.

• Hydraulically Telescoping Frame – The GT-3200's frame allows 36 inches (914 mm) of lateral leg movement to accommodate changing job site requirements. This means you can shift the mold deck without repositioning the entire machine, saving valuable time on every pour.

• Three-Track Crawler Design – The GT-3200 features a three-track crawler design for improved stability and maneuverability. Gear-driven and hydraulically powered with 11.8-inch track pads, the all-track drive system provides superior traction even on challenging terrain. It features two-speed track motors for speeds up to 136 feet per minute (41.5 mpm) during auxiliary travel.

• 3D Guidance Compatibility – The machine supports mmGPS and total station guidance systems, eliminating string lines and manual grade control for contractors who want to step into stringless paving.

• Quick-Detach Molds – The GT-3200 includes quick-detach molds for efficient profile changes. Swapping between curb, gutter, barrier wall, and flat slab profiles takes minutes rather than hours, keeping your crew productive instead of waiting.

How It Works

1. Setup and Positioning The telescoping frame adjusts up to 36 inches 914 mm of lateral movement to accommodate changing job site conditions. The GT-3200 can pour concrete on either side with adjustable track assembly, making it easy to set up regardless of site constraints. This machine is designed to perform in tight spaces and urban environments.

2. Concrete Delivery The auger system provides efficient concrete delivery to the mold through a standard 5.8 ft reversible charging auger with abrasion-resistant flighting. For higher-volume work, an optional 13.5 ft belt conveyor feeds the hopper continuously, allowing ready-mix trucks to discharge without repositioning. The GT-3200 allows for simultaneous trimming and pouring to maximize concrete utilization.

3. Precision Slipforming G+ controls and guidance sensors create perfect curb and gutter profiles at 50 FPM. Two hydraulic motor-in-head vibrators with four independent circuits ensure proper consolidation across the mold face. G+ controls offer instant digital feedback for smooth operation, and the result is a finished profile that requires minimal hand finishing.

Technical Specifications

The G+ control system provides a user-friendly interface and precise control. G+ operates in all major languages and measurement systems, features two-way communication with accessories, and includes a detailed fault history with timestamps for efficient service and diagnostics. G+ controls provide two-way communication with accessories, making the entire system work as one integrated unit.

The GT-3200 has a compact transport dimension for moving between job sites, and its relatively light class weight means fewer oversize transport permits compared to larger equipment.

It can be equipped with a sectionalized trimmerhead for obstacle clearance, featuring 14 inches of vertical lift and 36 inches of hydraulic sideshift, with a maximum trimmerhead width of 42 inches.

Ideal Applications

The GOMACO GT-3200 is the right equipment for projects that demand high-speed, precision concrete placement across the world:

• Municipal street and infrastructure projects – Long runs of curb and gutter on new or reconstructed roads where production speed translates directly to saved budget

• Commercial parking lot development – Extensive curb, gutter, and flat slabs placed efficiently across large site footprints

• Highway barrier wall construction – The machine can slipform barrier walls up to 40 inches tall, handling off-ramp and median barrier work with confidence

• Airport runway and taxiway projects – Strict profile tolerances and high volume requirements that benefit from consistent slipforming

• Housing development curb and gutter work – Subdivision infrastructure where the GT-3200 features front-steer capability enabling tight radius paving down to 24 inches, perfect for cul-de-sacs and curved streets

• Urban sidewalk replacement – The sidewalk variant with folding conveyor handles obstacles like light poles and trees, providing access to constrained areas that would challenge larger machines

Whether your company handles one application type or works across all of them, the GT-3200 adapts to share its power and efficiency across your entire project portfolio.

Frequently Asked Questions

How difficult is the GT-3200 to operate? The G+ control system makes operation straightforward to understand and learn. Operators of moderate experience typically become proficient within one to two job cycles. The 6.5-inch color anti-glare display provides intuitive feedback on grade, steering, deviation, and speed, so people can focus on quality rather than guesswork. The operator has an excellent view from the platform, which provides added confidence during every step of the paving process.

What concrete mix works best? Standard practice for curb slipforming calls for a slump of 3–5 inches with a maximum aggregate size of ¾ inch. Admixtures for workability and early strength are recommended. The GT-3200's four independent vibrator circuits compensate for minor mix variations, but consistent concrete delivery is important-over-slump leads to sagging profiles, while under-slump causes voids and poor consolidation.

Can it handle tight radii and corners? Yes. The GT-3200 can slipform a 24 inch (610 mm) radius using front-steer mode. The hydraulically telescoping frame provides 36 inches of lateral leg movement to accommodate changing job site geometry. For very tight turn situations, reduce speed and ensure the charging system feeds continuously to prevent voids on the inside of curves.

What maintenance is required? Key daily tasks include cleaning out concrete from the hopper and auger or conveyor, inspecting mold faces, checking vibrator circuits, and examining tracks and pads. Follow the Caterpillar engine maintenance schedule for the power plant, maintain hydraulic oil and filter schedules, and verify grade and slope sensors are functional. Stainless steel mold options help protect against corrosion and extend mold service life.

How does it compare to manual methods? Manual curb forming is significantly slower, more labor-intensive, and less consistent. The GT-3200's 50 FPM paving speed can more than double output compared to traditional methods. Fewer crew members are needed, alignment and grade errors are minimized through the G+ control system, and the consistent profile quality means contractors spend far less time on rework. The experience for satisfied crews is night-and-day different from hand forming.

What safety features does the machine include? The GT-3200 has emergency stop buttons on the operator's console, a backup alarm to alert personnel during reverse operation, track guards for enhanced safety around the drive system, and warning decals provided to inform operators of safety precautions. These security features protect crew members throughout every phase of operation.
