GOMACO Corporation’s new 4400 barrier machine for right-side and left-side slipforming made its World of Concrete show debut in 2012 at the Las Vegas Convention Center, Jan. 24 to 27. The new machine, built specifically for barrier applications, features operator comfort and visibility with its U-shaped operator’s platform featuring vibration isolation and a high-capacity cooling package on the engine. Ease in operation also is provided by the GOMACO’s G+ control system, which is capable of operating in multiple languages.

GOMACO engineers built the new 4400 around the design concept of a left-side and right-side slipforming capable machine with symmetrical steering and minimal set-up changes for switching profiles from side-to-side. Its GOMACO U-shaped operator’s platform, with vibration isolation, puts the operator on top of the action. The U-shaped platform and side-to-side sliding control console accommodate right-side and left-side pour and provide a 360 degree view of the entire paving operation.

The 4400 features a Cummins QSB3.3, 99 hp (74 kW), Tier III power-optimized diesel engine for fuel efficiency and approximately 18 hours of continuous barrier slipform paving. The new G+ control system coordinates the speed of the hydraulic fan with engine and hydraulic oil temperature. The tractive system on the 4400 features super low, allowing for the minimum speed and smooth crawl necessary for a vertical wall. The new G+ speed dial turns to adjust in one percent increments and speed display feedback allows for smooth, precision paving speed control.

It has the new GOMACO Barrier Hook-and-Go mold mounting system to quickly mount barrier molds up to 39.4 in. (100 cm) tall on either side of the machine. An optional sidemount attachment is available for barriers taller than 39.4 in. or existing barrier molds.

GOMACO barrier molds are designed for proper vibration and consolidation of material, with the GOMACO-exclusive trailing stainless steel for superior finishing. The barrier machine features the new 4400 series, 16 in. (40.6 cm) diameter auger, with the pitch and speed designed specifically for transporting low-slump concrete. Its four-way hydraulic positioning capability allows the auger to be placed perfectly for concrete receiving and delivery to the mold on either side of the machine.
