Sidemounted Trimmer For GT-3400 Trimmer

GOMACO has developed an attachment for the trimming of narrower widths for scab-on curb and gutter slipforming applications with the GT-3400 trimmer.

The GT-3400 trimmer’s new sidemounted trimmerhead attachment has a powerful, closed-loop trimmer that is 30 inches (762 mm) wide and has a wheel diameter of 56 inches (1422 mm). It features framework on the front to support the trimmerhead. The new trimmer has 18 inches (457 mm) of hydraulic vertical lift for depth adjustments and for easy shipping on a trailer. It also has a third conveyor for moving material. The extra conveyor transfers the trimmed material from the trimmerhead to the standard transfer conveyor.

G+ ConnectTM - A Revolutionary Control System For GOMACO Equipment

The proprietary CAN-based network on GOMACO products that allows fast, two-way communications between all accessories and the G+ controller.

GOMACO's exclusive G+ Connect is a closed-loop control system for both the electronics and hydraulics on GOMACO pavers. The closed-loop system between the paver's valve drives and various sensors means unparalleled accuracy. The sensored feedback ensures tighter, faster, and more accurate machine corrections. G+ Connect utilizes a CAN (control area network) network allowing all of the components of the system to easily communicate with each other for precision setup and paving. At the heart of G+ Connect is the G+ control system, GOMACO's proprietary software and control system.

Paver-Mounted GSI®

Immediate smoothness readings are available with the GSI on-board your paver. The paver-mounted GSI is a cost-effective quality control tool that is quick and easy to install on your GOMACO paver. Since it's on-board the paver, any interference with the rest of the paving train or finishing crew is minimal. It also has the capability of reading multiple traces, from one to eight.

The effectiveness and quality of the GSI has been verified by contractors on projects around the world and by independent studies.

Hydraulic Side Bar Inserter (SBI)

The GOMACO Hydraulic Side Bar Inserter (SBI) is designed to insert straight tie bars into the side of a newly paved slab using hydraulic force to insert the bar. Vibration, which is adjustable in a range of 2000 to 6000 vpm, is applied to the bar during the insertion process to assist with penetration and also consolidation of material around the bar. The insertion apparatus maintains its position with the side of the slab, as the paver continues to move forward during insertion of the bar. The SBI can be fitted to either the left side or right side of the paver or an inserter can be placed on both sides.

Commander III 4-Track Features Roller Frame

A roller frame provides easy and accurate width changes. The Commander III's frame hydraulically telescopes on the left side up to 6 ft. (1.83 m). The dual rollers, mounted to the top and bottom of the outer frame tubes, position the inner tube and reduce the amount of surface to surface contact area. This reduces friction and drag as the inner tube rolls when telescoping. The roller frame was originally developed for the Commander III with a V2 mold. The V2 is GOMACO's dual mold system that is hydraulically adjustable for paving at different widths. The roller frame provides a fluid action as the V2 mold is making on-the-go width changes for tapered slabs. The roller frame is now standard on all GOMACO Commander III four-track machines. It can also be retrofitted in the field on existing Commander IIIs.

Optional Folding Rear Conveyor Belt For 9500

The GOMACO 9500 trimmer or placer is available with an optional rear folding conveyor. The option allows the conveyor to remain attached to the 9500 during shipping. The 9500's shipping length, with the new folding rear conveyor, is just 41.8 feet (12.7 m). Shipping height is 11.5 feet (3.5 m).

Engineers rebuilt the conveyor to be stronger and more rigid with a new, truss-style framework. The switch to control the hydraulic folding operation of the conveyor can be placed at different locations on the back of the machine. The belt width is still 36 inches (914 mm) and the rear conveyor maintains its 160 degree swing with hydraulic height adjustment up to 12 feet (3.7 m). It has a 34.7 feet (10.6 m) long reach during machine operation, with a conveyor belt speed of 504 feet per minute (153.6 mpm) allowing fast placing of concrete or removal of trimmed material.

C-450 With Transitional Framework

The transitional framework is a new design option for the GOMACO C-450 cylinder finisher that provides faster assembly and weight savings compared to wider-width finishers requiring an overhead truss system. The new frame features transition sections connecting the C-450's standard 24 inch (610 mm) tall framework to the 42 inch (1067 mm) tall framework used on a C-750 finisher. The frame sections only need to be pin-connected and the cross arms bolted in place.

The overhead truss system is eliminated. The transitional framework not only provides a much quicker assembly time, but also decreases the weight of the machine considerably. It is estimated to be eight pounds per foot (11.9 kg/m) lighter when compared to a machine with overhead truss.

The transitional framework sections can also be removed and the C-450 can finish at smaller widths with its standard 24 inch (610 mm) framework. The new framework allows the versatility of two finishers in one for the narrower or wider widths. The new transitional framework can be added to new or existing C-450s.

GOMACO's line of bridge deck finishers is also available with the optional third wheel assist on the standard bogies to further distribute the machine's weight while traveling on the rails. The optional third wheel assist bogies, on each side of the finisher, consist of two single-wheel idler bogies attached to the spreader beam. It's a simple modification that can be made to any C-450 or C-750 to help spread the weight out and reduce the wheel load on the overhang brackets.

The All-American Canal: Slipforming 72 Feet (21.9 m) Wide...

The All-American Canal lining project through the Imperial Valley in California called for a new 23 mile (37 km) long concrete-lined canal to be built parallel to the existing unlined canal. Coffman Specialties would pave the six mile (9.7 km) long Reach Two and four mile (6.4 km) long Reach Three of the project. The proposed lined sections would have slopes of 1.75:1 and 2:1, a bottom width of 50 feet (15.2 m) and a top width spanning 150 feet (45.7 m). Slope widths would be variable, between 37.3 feet (11.4 m) and 45.7 feet (14 m). The concrete lining itself would be four inches (102 mm) thick.

The first piece of equipment was the canal paver. A GOMACO GP-4000 prime mover, set on top of a ten foot (3 m) tall framework, provides the power plant and control system for the paver. The mold sections are a 5000 series paving mold which were slightly modified. The machine is mounted on four tracks that are 13 feet, nine inches (4.2 m) long, 30 inches (762 mm) wide and 40 inches (1016 mm) high.

The second piece of equipment GOMACO built for the All-American Canal paving train is the water stop machine. It follows directly behind the canal paver inserting the transverse water stop material every 15 feet (4.6 m).

The work bridge is the third piece of equipment in Coffman Specialties’ canal paving train. It gives finishers a platform to work from and is used to cure the finished canal. A curing mechanism is mounted to the back of the work bridge to apply the white curing compound.

Place Stone Base Material With The PS-2600

A PS-2600 placer/spreader was recently equipped with a rock hopper to place stone base material. It was developed for a customer who needed a machine that could carry base material, rather than pushing a pile like regular placer/spreaders. After the material placement, the machine can be converted back to a traditional PS-2600 by removing the rock hopper and attaching the concrete strike-off and belt.

More on the PS-2600 placer/spreader and the rock hopper for placer/spreaders

GOMACO equipment will slipform concrete streets and highways, airport runways, curb and gutter, sidewalks and recreational trails, safety barrier, bridge parapet and irrigation canals.

Support equipment includes grade trimmers, concrete placers, concrete placer/spreaders and texturing and curing machines. We also offer equipment to finish flat slabs, bridges, and slopes.

GOMACO will consult on equipment for large or unique concrete paving projects. Our products are offered through a worldwide distributor network for local sales, parts and service expertise.
