Horizontal Directional Drilling - Directional-thrust boring machine

The PD-6 directional-thrust boring machine from Pow-r Mole Sales was designed for use in difficult soil conditions where a pipe or cable is to be installed under a road or in an area that cannot be dug. It can install pipes by either directional-thrust boring or pipe bursting. It can operate from a pit only 56 inches long and has a thrust force of 84,822 pounds at 3,000 psi. The maximum push rate is 7 feet per minute and it can install up to 8-inch ID pipe in most compressible soils. The high-strength steel frame is protected with a chrome-plated steel guide bar. The pushing mechanism slides on bronze bushings and uses wiper seals to keep lubricant in and water and dirt out. 800/344-6653; www.powrmole.com.
