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.
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.
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.
The 4400 paves a sidewalk with finishers applying a hand-broomed texture behind the machine.
A 9500 placer works in front of a 4400 barrier paver on a project in southern Russia. The project is the M4 Don Federal Highway between the cities of Rostov-on-Don and Karasnodar in southern Russia.
The 4400 slipforms a 19.7 inch (500 mm) slot drain.
The 4400's U-shaped operator's platform, with vibration isolation, puts the operator comfortably 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 degree view of the entire paving operation.
The right-side pour barrier wall is slipformed on top of a footer, right next to a new sound wall along the Capital Beltway.
The 4400 uses 3D stringless technology to slipform a barrier.
This contractor used one of their existing barrier molds on their first pour with their new 4400.
This 4400 slipforms left-side pour U-channel,500 millimeters (19.7 in) tall, below grade next to an existing roadway on the island of Mauritius.
The 4400 slipforms left-side mount barrier wall next to traffic.
GOMACO's 4400, with the auger still attached, can be driven right into a container for ease in ocean freight 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.
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).
What we really wanted with the 4400 was the capability to pour wall with the direction of traffic. Plus, I like the 4400’s size, the fact that it’s equipped with an auger, and the way it’s built to be a barrier machine. The 4400 is performing really well. We haven’t had to worry about our new machine’s performance at all. That 4400 is just so smooth. The smoother a machine operates, the smoother the finish will be on the wall, and you only have to look at the wall to see how nice it is.
Good Paver For Us
We’ve had that machine (4400) for one and one half years now and have put some serious hours on it. It has been a very good paver to us.
I Would Recommend it to Other Barrier Contractors
It is great, but that’s what I expected from GOMACO. The 4400 is very handy when you are working in close quarters in traffic. It’s a compact machine and doesn’t take a lot of room. And pouring from the right side makes things easier, especially with our ready-mix trucks, because we don’t need as much room to get them positioned and turned around. The GOMACO 4400 is a good machine for barrier and has been designed well for balance, stability, and sturdiness. I am very happy with it and I would recommend it to other barrier contractors.
