Designed For Safety

The GP-2400 is carefully designed to give years of dependable and safe service. The emergency stop buttons are on the operator's console, and on corners of the machine, which are easily accessible from the ground level. Another safety feature is a backup alarm, which is designed to alert personnel around the machine when the tracks are set to operate in reverse. Other safety features include track guards, warning decals, an operator's manual, and a safety manual. GOMACO machines are also designed to provide the operator with excellent visibility over the entire paving operation.

GOMACO Corporation recommends the implementation of all safety procedures.





GP-2400 Pours Safety Barrier With or Against Traffic


GP-2400 graphic


The versatile design of the GP-2400 four-track paver allows it to be a unique barrier machine capable of slipforming with or against traffic. Barrier paving is accomplished by swinging the paver’s four legs to the outboard or transport position. The G+ control system on the GP-2400 has the ability to pave in Normal, Transport Mode Right, or Transport Mode Left. A 24 inch (610 mm) wide conveyor attaches to mountings on the front of the machine for concrete delivery and can be positioned accordingly.

Bar Insertion Versatility


Bar Insertion Systems Designed to Fit Your Project Specifications

GOMACO offers several bar insertion systems that are designed to accommodate your project specifications. Hydraulic cylinder, air-powered, and manual insertion are the three types of bar insertion. Bar inserters include the frame-mounted, sidemounted, 5400 series, and trailing form. GOMACO’s bar inserters provide easy and accurate bar placement to job specifications.



5400 Series Bar Inserter

5400 series bar inserter

The 5400 series bar inserter is front or rear loading and front inserting for ease of use. It mounts to the mold's T-bar and allows on-the-go crown changes, while maintaining a constant depth. The bar box is mounted to the paver's rear T-beam mounting rail for easy access and loading of the bar magazine. There are individual depth guides on the right and the left side of the bar inserter in order to keep bars parallel to the top of slab. The 5400 series bar inserter can hold up to 50 bars in the bar magazine and bar loading chain system.




trailing form

The trailing form with manual, air-powered, or hydraulic bar insertion is designed to trail the track on two-track pavers. This system will accommodate most types of bars.

hydraulic powered magazine-style side bar inserter

The hydraulic powered magazine-style side bar inserter allows personnel to load multiple bars into a magazine clip. The bar inserter then releases a single bar and places it at the specified distance.




The hydraulic system includes vibration to the bar, and is designed for large bars. Vibration is applied to the bar during insertion, which provides consolidation of concrete around the bars. This system requires one vibrator circuit. The minimum slab depth required is six inches (152 mm) and the maximum bar length is 48 inches (1219 mm).

Trailing Form and Bar Inserter

The trailing form and manual bar inserter is designed to trail the track on a two-track paver. This system will accommodate most types of bars.

GOMACO’s Navigator


• The GOMACO Navigator software and display screen is an optional add-on for your paver to bring all of your G+ paver accessories together for easy control and monitoring.

• The touchscreen can be mounted at ground level on the paver to allow personnel the ability to fine tune the slipform paver's performance and configure settings for the GSI® (GOMACO Smoothness Indicator), SBI (side bar inserter), TBI (tie bar inserter), and PTA (power transition adjuster).

• Ground personnel can monitor the elevation and steering deviations for the machine and adjust sensitivities when required. The deviation meters are customizable and can be shown in a G+ bar graph, circular, or oscilloscope/histogram mode.

• The Navigator can be configured to make G+ accessories available on older G21/G22 slipform pavers.


Navigator’s home screen

Navigator GSI


• GSI (GOMACO Smoothness Indicator) utilizes compact and ruggedized CAN-based sonic sensors and a CAN-based digital slope sensor to read the smoothness profile anywhere on the slab’s surface.

• The GSI is mounted on lightweight aluminum to allow for easy handling and assembly with less maintenance. The lower profile mounting system allows the work bridge to be mounted directly above the GSI, if needed.

• The optional Navigator’s GSI (GOMACO Smoothness Indicator) screen allows ground personnel to monitor paving smoothness for up to four GSI traces (two visible at a time) using either a real-time localized roughness graph or a simulated California profilograph.

• The machine speed is now logged, which makes it possible to relate the machine speed with the smoothness, as well as automatically track the machine's start and stop events.

digital diagnostics

The LCD screens provide digital diagnostics at the sensor location or can send readouts to the optional Navigator system attached on the side of the paver.








Navigator Accessories

• The ACC (Accessories) tab on the Navigator will allow ground personnel to monitor the real time operation of the tie bar inserter (TBI), side bar inserter (SBI), and power transition adjuster (PTA).

• The Navigator supports up to four PTAs. To transition the PTAs, simply enter the new target height values for each PTA, enter the transition distance, and press start transition. The yellow line represents the current height of each PTA, and the red line represents the target height for each PTA.

• Up to four TBIs and two SBIs are supported on the Navigator. The machine position in relation to the current dowel bar spacings is indicated by the red vertical line that will travel across the screen when the machine is moving. When the paver (red line) passes a TBI/SBI fire position, the fire lamps are illuminated.


ACC (Accessories) screen

ACC (Accessories) Screen shows how many PTAs, TBIs, and SBIs are set up on the paver, and the distance between them.



TBI/SBI setup menu

Personnel enter the number of bars required between each horizontal joint into the TBI/SBI setup menu. Navigator then calculates the space between each bar and the horizontal joint and makes managing bar placement simple and easy.
