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.
GOMACO's Exclusive Proprietary Software And Control System
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.
High-production variable barrier was achieved with a GOMACO RTP-500 rubber-tracked placer and 4400 barrier machine.

The right-side pour barrier wall is slipformed on top of a footer, right next to a new sound wall along the Capital Beltway.
Taller or existing barrier molds can be utilized on the 4400. Side-mounting adaptors for the molds include adding a section of framework and adaptor flanges (shown below). The added sections allow these molds to be attached to the 4400.
Left-side pour, with side-mounting attachments for barrier wall over 39.4 inches (1000 mm) tall or existing barrier molds.
Both of these drawings illustrate the maximum amount of sideshift available on the 4400's barrier mold and tracks in either the right-side or left-side pour configuration. The hydraulic mold mounting beams telescope on the right or left side up to 36 inches (914 mm).
