Pipe Bursting Tools

Modular pipe bursting machine

The Model PD-33 pipe bursting machine from Pow-r Mole Sales has a 24-inch stroke. Its nonslip cylinder-activated jaws prevent cable damage, while developing 60,000 pounds of pulling force at a rate of 6 feet per minute. It offers a cost-effective alternative to open-cut by reducing excavation up to 85 percent, and can burst cast-iron, concrete, HDPE, asbestos cement, PVC, ductile iron, Orangeburg and clay pipe from 2 to 6 inches. It’s a modular machine and can be disassembled into easily transported pieces with no single part weighing over 98 pounds. 800/344-6653; www.powrmole.com.

Pipe bursting puller

The Model 7000 pipe bursting puller from Poweram replaces existing utilities by pulling pipe splitting and/or bursting tools through the old pipe and pulling a new pipe into the same space. The new pipe can be the same size or larger than the old pipe. With over 118,000 pounds of pulling force, it can split or burst up to 12-inch pipe and pull back up to 16-inch pipe in most soil conditions. The longest practical distance depends on the type of pipe to be replaced, terrain (grade changes), soil conditions, and repair couplings or splice pieces encountered. 715/537-9050; www.poweram.com.

Lateral pipe bursting machine

The lightweight lateral pipe bursting machine from RODDIE Inc. slides apart into two components of 50 and 60 pounds that can be lowered and reassembled by hand in the excavated pulling pit. In most cases this machine is powered and operated by a mini-excavator or bobcat tractor. It is capable of a pulling force of 30 to 50 tons, and can be used on 4-, 6- and 8-inch sewer laterals, but can also replace 1- to 4-inch water services. 888/406-3821; www.pipeburstingamerica.com.

Pipe bursting system

The UnderTaker pipe bursting system from Spartan Tool will replace existing sewer laterals with new, seamless, high-flow HDPE pipe from 2 to 6 inches in diameter. The system sets up quickly, without any tools, and handles up to three 45-degree bends in the existing pipe. No component weighs over 70 pounds, so it’s easy to position for any job with very minimal disruption to the customer’s yard or business. 800/435-3866; www.spartantool.com.

Hydraulic bursting pump

The ergonomic Hi-Flow 13HP hydraulic pump from TRIC Tools delivers 4 gpm up to 5,000 psi, measures 28 by 27 by 26 inches, and weighs about 280 pounds wet.
