Steering The Bore
The PD-6 was designed for use in difficult soil conditions where a pipe or cable is to be installed under a road or
in an area which cannot be dug. The PD-6 can install pipes by either directional thrust boring or pipe bursting.
These machines are excellent in areas where space is limited.
The PD-6 will operate from a pit only 56 inches long and has a thrust force of 84,822 lbs@ 3,000 psi.
The maximum push rate of PD-6 is 7 feet/minute and it can install up to 8-inch ID pipe in most compressible soils.
Minimum Maintenance-Maximum Life
The high strength steel frame is protected from wearing forces by a chrome plated steel guide bar. The pushing
mechanism slides on bronze bushings and uses special wiper seals to keep the lubricant in and the water and dirt
out. The patented mechanism provides long lasting service with a minimum of maintenance.
How It Works
The Model PD-6 uses a cylinder-actuated positive-locking, non-slip jaw assembly that provides a steady force when
driving push rods. Sections of 2.5' push rods are screwed together and thrust into the ground. When the target
pit is reached, the steering head is removed and the appropriate ground expander is attached. The pipe or cable
that is to be installed is attached with a grip to the expander and the rods are retrieved until the pipe is installed.

The PD-6 uses detection technology located in the head of the rod to accurately establish its location
underground to within inches. The detection equipment provides information that indicates the orientation,
location and depth of our conically shaped steering head. This allows you to guide the rods around obstacles
such as pipes, ducting and building foundations safely and accurately until the final target is reached.
