GOMACO’s GP-2400 is the latest paver in its complete line of concrete slipform pavers to feature the V2 variable-width mold. The GP-2400 is capable of paving up to 24 ft. (7.5 m) wide and with the V2 mold on board, it can make 6.5 ft. (2 m) transitions to form tapered slabs on-the-go and make easy paving width changes.

The GP-2400 with V2 mold paving package features a hydraulically telescoping rolling frame for easy and accurate width changes. The frame has dual rollers, mounted to the top and bottom of the outer frame tubes, to position the inner tube and reduces the amount of surface-to-surface contact area. This reduces friction and drag as the inner tube rolls when telescoping and provides a fluid action as the V2 mold makes on-the-go width changes. The configuration of the front and rear molds dictates the minimum and maximum paving widths and the total amount of width variation. The molds feature dual power transition adjusters (PTAs) for crown height adjustment. It also is available with a curb profile on one or both sides for municipal paving.

A spreader plow with hydraulic vertical movement controls the head of concrete in front of the V2 sectionalized mold system. The plow rail has the ability to vary similar to the GP-2400’s framework to accommodate width changes. Proximity switches on the plow framework set the length of travel and these switches can be easily moved to change the plow’s settings. The plow’s horizontal and vertical movement can be operated manually or set on automatic.

The GOMACO GP-2400 two-track or four-track slipform paver is powered by a 174.5 hp (129.5 kW) Caterpillar diesel engine. Two-speed track motors provide quick jobsite mobility. The travel speed on the two-track GP-2400 is 105 ft. per minute (32 mpm), and up to 96 ft. per minute (29 mpm) for the four-track paver, to quickly move across the job site or travel from one pour to the next. Low speed is variable and features the smooth crawl that GOMACO pavers are known for when slipforming concrete.

The GP-2400 features the GOMACO-exclusive G+ control system that is both easy to learn and easy to operate. It expresses itself in easy to understand international icons and full script explanations. G+ operates in all the major languages of the world in either imperial or metric units. It has a lightning-fast processing speed and features two-way communications between paver accessories and the G+ controller. Its instant digital feedback combined with the tight closed-loop electronic and hydraulic control creates a G+ paving experience that is smooth, efficient, and accurate, according to the manufacturer.

G+ Connect features an entire library of sensor capabilities for controlling slope, grade and steer with set-up configurations for any project requirement. This includes paving with 3D stringless systems, laser control, sonic sensors, rotary sensors, slope sensors and all of their set-up requirements. Just connect to G+ Connect and the G+ controls automatically recognize them and communicates with them. Unique applications such as fill-in lanes, tunnel paving, half-width concrete overlays, and sonar steering off an existing barrier wall are examples of projects that can be accomplished through a variety of solutions from the Sensor Library.
