| Attachment for Super-B slipform paver Power Curber has developed a new attachment for its 5700-Super-B slipform paver that automates the installation of steel cable barriers in highway medians. The company's post-hole digger attachment allows the machine to dig pier holes up to 34" deep, then slipform concrete foundations for steel cable posts. The process is faster than current manual methods and produces a concrete foundation that prevents grass from growing around the posts, simplifying grass-cutting maintenance. The post-hole digger attachment mounts on the left rear of the 5700-Super-B and is powered with the machine's auger conveyor circuit. The auger for the post-hole digger operates inside a cylinder. It moves the dirt upward into a hinged chute, catching the material before it hits the ground. The hinged chute allows the material to be dumped out of the way of the slipform application and eliminates the need for a crew member to move the dirt manually. After the holes are dug, the 5700-Super-B slipforms the foundation, filling the holes with concrete as it passes over them. The machine's vibrators consolidate and strengthen the concrete, eliminating voids, then a crew member inserts a tube into the pier. A steel post is inserted into each tube and the wire rope is strung between the posts. write your comments about the article :: © 2006 Construction News :: home page |
