Designed For Safety

The 4400 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 Corporation recommends the implementation of all safety procedures.



G+® Controls – Positively Simple!

GOMACO's Exclusive Proprietary Software And Control System

4400 G+ controls

The 4400 barrier paver features the exclusive GOMACO G+ control system with self-diagnostics for grade and steering. It is able to operate in multiple languages, by customer choice, and offers metric or imperial measurements. The G+ control system has been designed in-house by GOMACO's control experts. It features new and easy-to-operate hardware with steering and travel dials. The elevation jog buttons, located to the left of the display screen, are used to manually change the elevation of the leg when the control loop is set to manual mode. The steering jog buttons, located above the display screen, are used to manually change the steer direction of the leg when the control loop is in the manual mode. A full color display on the control panel illustrates the various aspects of the paver for set up and operation.

4400 tall wall

Production on this project near Springdale, Arkansas, averaged 600 feet (183 m) per night. The contractor slipformed 76 to 78 inch (1930 to 1981 mm) tall wall over steel-cage reinforcing with a GOMACO 4400.




4400 bridge parapet

This crew slipforms new bridge parapet on a flyover for the Memphis I-40/240 interchange project. They are working 108 feet (33 m) above ground level with their GOMACO 4400 barrier paver.

4400 barrier

The hydraulic system design of the 4400, along with the effectiveness of load-sensed pumps, proportional solenoids, and the G+ control system, helps to optimize fuel efficiency for a minimum of 18 hours of operation per tank.




4400 sidewalk

The 4400 paves a sidewalk with finishers applying a hand-broomed texture behind the machine.

4400 shipping

GOMACO's 4400, with the auger still attached, can be driven right into a container for ease in ocean freight shipping.




4400 shipping

A wired remote, which interfaces with the 4400's G+ control system, was designed to guide the machine into and out of the container.




4400 tall variable barrier

This 4400 slipformed a variable barrier with 36 inches (914 mm) of variable height adjustment on each side and can reach a wall height as tall as 6.5 feet (2 m).
