Gomaco will use ConExpo to launch its new 4400 barrier slipformer. A new frame design means barriers can be formed either to the left or right, and the control console can be moved from side to side for the best possible visibility. Features also include the company's G+ control system, which makes the machine simple to use and is available in a variety of languages. Power comes from a 99 hp (74 kW) Cummins QSB 3.9 engine.
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 standing vertical wall. The new G+ speed dial turns to adjust in deviations of 1% increments and speed display feedback allows for smooth, precision paving speed control.
The 4400's unique 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 console accommodate right-side and left-side pour and provide a 360° view of the entire paving operation. Safety is first in all of Gomaco's design considerations. The 4400 features track guards and ground level emergency stops to keep everyone safe while working around the machine.
The 4400 includes Gomaco's 'barrier Hook-and-Go' system, which allows barrier moulds up to 1 m high to be mounted quickly on either side of the machine. A standard side mount is available for larger structures.
It also features the new 4400 series auger with the pitch and speed designed specifically for transporting low slump concrete. The sixteen inch (406 mm) diameter auger has polyurethane, bolt-on blade liners for extended wear and protection. 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.
