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. This system is capable of bursting cast iron, concrete, asbestos cement, PVC, ductile iron, orangeburg and clay pipe from 3 to 8 inches. 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 or pulling rods. Sections of 2.5' push rods are screwed together and thrust into the ground or existing pipe. When the target pit is reached, the lead head is removed and the appropriate ground expander or pipe bursting expander is attached. The pipe that is to be installed is attached with a grip to the expander and the rods are retrieved until the pipe is installed.
