Designed To Meet Worldwide Demands In Slipform Paving, Superior Quality And Technology That No One Else Can Offer

The job-proven GOMACO GP-2600 is preferred by contractors throughout the world. All of the features that have made the GP-2600 the “Number One” mid-range paver in universal paving markets are still standard. The GP-2600 has even more outstanding features that provide today’s contractor with the ultimate paving machine of the future.

GOMACO provides the highest standard of quality in the industry with skilled personnel producing state-of-the-art machines. The GP-2600 mid-range paver is built with durability for construction job-site conditions. Quality control from GOMACO engineering through manufacturing provides low-maintenance equipment with superior paving performance. Safety standards are a priority in equipment designs.

The engineering teams have designed the GP-2600 for maximum versatility with proven rideability results. GOMACO has provided quality, versatility, proven performance, and dedication to customer satisfaction for over 40 years and will continue to meet the challenges of today and into the future.

The GP-2600 slipform paver is designed to meet the worldwide demands in new and reconstruction of highways, streets, parking lots, and airport pavements. This slipform paver is available with two or four tracks to meet varying applications and contractor preference.

The GP-2600 modular telescoping frame provides versatility. The GP-2600 provides contractors with a broad range of paving widths from 12 ft. (3.66 m) to 18 ft. 6 in. (5.64 m) with the unique telescoping frame that extends 6 ft. 6 in. (1.98 m) on the left side. The GP-2600 will pave widths up to 32 ft. (9.75 m) with additional frame inserts. Hydraulically pressure-compensated sideplates provide edge control and a paving depth up to 19 in. (483 mm).

Production and serviceability are key factors with the GP-2600. Over 10 percent more fuel capacity combined with engine fuel efficiency provide an extended day of paving, resulting in higher production. The segmented fiberglass shroud provides ease in serviceability. One section lifts up to allow easy access to the engine and service points.

The low-profile engine shroud designed for the GP-2600 provides enhanced rear visibility for the operator. This allows the operator to remain at the controls and see the entire paving operation. The GP-2600 is powered by a 275 hp (205.2 kW) Caterpillar, emission-controlled diesel engine.

An optional removable auger/strike-off offers ease in changing widths and transportability. The detachable telescoping auger/strike-off 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 is designed to move independently with hydraulically-adjustable mounts on the front of the mold. A self-supporting transition adjuster (TA) is standard to allow for crowning. Both the strike-off and the augers have 6 ft. (1.83 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 with 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 sideplate can be folded in to allow a four-track paver, with the mold still mounted underneath it, to be transported on one truck under 12 ft. (3.66 m) wide.

GOMACO’s Control System Easily Interfaces With Stringless Technology

GOMACO Corporation has the control system of the future. The G21 technology allows GOMACO’s slipform pavers, trimmers, and placer/spreaders to be controlled by an automated 3-D machine-control system and not by stringline. The 3-D control system is adaptable to the exclusive G21 control system. This system can accommodate radii or superelevations automatically according to design data.

Real-time navigation systems allow the project data created in the CAD system to be directly put into the paving process. There is no stringline installation or maintenance. The stringless control systems can save you time and money.

Unparalleled Accuracy With The GOMACO Power Transition Adjuster (PTA)

GOMACO’s hydraulically powered transition adjuster (PTA) provides on-the-go transitions in the crown of the concrete slab.

A switch in the operator’s console controls the PTA in a positive or negative (up or down) motion. This eliminates the crown in the paving mold/slab or brings the crown back into the mold/slab. These transitions are necessary in paving through superelevations and intersections. This simple solution provides an easy method for an operator to perform a smooth transition where necessary and accomplish the required slab profile as specified.

GOMACO’s Computerized Transition Adjuster

The illustration above shows a stretch of roadway with a 3 in. (76 mm) crown to a zero (0) crown into a superelevation and out from zero (0) crown to a 3 in. (76 mm) crown. The operator has dialed in a minimum crown of zero (0) and a maximum crown of 3 in. (76 mm). The encoder wheel assemblies positioned on two of the tracks measures the distance of the two track lines inside and outside of the slab. The transition computer automatically averages these two distances to the total change from minimum to maximum crown over the total distance entered for the transition.

GOMACO offers a computerized transition adjuster that meets the increasing demands for a smooth riding surface. The optional specialized computer control allows for smooth transitions from a crown to a flat cross slope in a superelevation, or vice versa, calculating the number of steps to make the transitions.

The computer controls and synchronizes the power transition adjuster (PTA) on the paver to make the necessary adjustments as specific stations are reached in the transition.

GOMACO’S Sensor Equipment Is Reliable And Cost Effective

Sensor line and sensors provide the grade and steering information linked to the GOMACO G21 digital operating system, located on the operator panel.

The GOMACO electronic-over-hydraulic sensor system provides intelligent control of grade and steering for paving accuracy, superior rideability and ease of operation.

GOMACO sensor line is designed specifically for electronically controlled equipment. GOMACO line rods are 3/8 in. (9.5 mm) diameter plated steel. The 18 in. (457 mm) length of the line rods allow an adjustment range of 12 in. (305 mm) for sensoring accuracy. The line rod clamps are rustproof and durable, made of solid aluminum.

GOMACO’s 48 in. (1219 mm) long sensor line stakes are machine tapered for easy driving and fast setup. The 3/4 in. (19 mm) diameter stake resists bending.
