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.

GOMACO's New G22 Operating System
|
-
The G22 is a revolutionary software and operating system that combines intelligence with simplicity for GOMACO construction equipment. The new graphical display provides the operator with an easy to understand interface to the machine controls. The G22 operating system is exclusive to GOMACO products.
- The G22 features a 6.5 in. (165 mm) anti-glare display screen with sensor-controlled backlight levels and the new TFT flat panel technology. It provides superior visibility under all operating conditions.
- A dual language option is available on the G22.
- The exclusive G22 provides push-button steering setup and trainable track steering when interfaced with GOMACO “smart” cylinders. Steering control has been simplified with the exclusive “smart” cylinders, used for dependable steering control feedback.
- The optional transition software system allows the operator to automatically transition in and out of “catch” or “spill” gutter.
- Advanced system diagnostics of the G22 automatically pinpoint and identify electrical circuit opens, shorts and fault codes to aid in troubleshooting.
- The G22 has more room for future expansion.
- Available as an option on the Commander III, GT-3600 curb and gutter machine, GT-3400 curb and gutter machine, GHP-2800 slipform paver, GP-2600 slipform paver, GP-4000 slipform paver, 9500 trimmer, and PS-2600 placer/spreader.

Skewed Tining Option Available For GOMACO Texture/Cure Machines
|
-
GOMACO’s T/C-400 and T/C-600 texture/cure machines are available with a skewed tining option. It allows the travel of the tining bars to run a skewed path, while the frame of the machine is square to the slab.
- The sprockets, chains and mechanical items are off-the-shelf pieces that are easily replaceable. The tine rake on the texture/cure is gear driven, and as the rake travels across the slab, it moves longitudinally in a sliding mechanism through the mount. The final tining pattern is accomplished simply by sliding only the rake.
- The sliding movement is controlled by a timing chain that runs from end panel to end panel. The direction of the skew can easily be changed by moving the timing chain either over or under the main drive sprocket on the upper carriage.
- The skewed tining option can also be easily retrofitted to existing GOMACO texture/cure machines.

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.

Removable Auger/Strike-Off For Width Changes And Shipping
|
 A special request by a customer has led to a GOMACO innovation, a paving mold with a detachable telescoping auger/strike-off. This innovation gives contractors the benefit of a mold that can be either an open front or auger/strike-off. It can then easily be broken down with removable and telescoping sections.
The auger/strike-off moves independently with hydraulically-adjustable mounts on the front of the mold. A self-supporting transition adjuster (TA) is standard to allow for crowning in the pavement.
Both the strike-off and auger have six feet (1.8 m) of telescoping capabilities to aid in changing paving widths. When paving widths need to be changed, the contractor only has to add or remove a section of the paving mold and then telescope the auger and strike-off in or out depending on the needed width. The telescoping auger incorporates bolt-on flighting to accommodate the changing widths.
Along with giving the contractor some extra versatility on their pavers, the detachable telescoping auger/strike-off can ease transportation. The auger/strike-off can be detached from the front of the mold and the wings on the sideplates can be folded in to allow the paver, with the mold still mounted underneath it, to be transported on one truck under 12 feet (3.7 m) wide.
The new design is based on a 5000 series open-front mold, allowing such molds to be retrofitted in the field.

Half-Width Placing With An RC Conveyor
|
 Here’s an economical system for quick discharge from ready-mix trucks. The RC Conveyor for half-width placing is a powered system with a unique divert-a-car for placing the concrete across the width of the slab. This has become a popular product with the need to get concrete trucks on and off the job site without piling the material. The RC Conveyor can reduce the number of trucks necessary, depending on job-site logistics.
