Focus on Pipe Bursting From HammerHead® Trenchless at UCT 2016

Pipe bursting contractors now have 99 tons of pulling force for their sewer, water and gas line replacement jobs from the new, powerful, compact HydroBurst® 100XT static pipe bursting system from HammerHead Trenchless Equipment. Featuring tethered remote control, the streamlined 100XT pays out rod very quickly due to the pipe industry’s first automated rod spinning assembly and the unique design of its hydraulic cylinders. The company featured the new product at their booth at the Underground Construction Technology International Conference and Exhibition in Atlanta in early February.

Alan Goodman is a global sales manager for HammerHead Trenchless Equipment. He said that the 100XT might be the only bursting machine some contractors ever need. The unit weighs just 3,200 pounds and is only 39 inches high by 30 inches wide.

“It has the muscle to replace pipes up to 16 inches in diameter,” Goodman said, “yet is compact enough they won’t mind using it for pipes as small as 4 inches.”

The pulling machine’s water-cooled PP4500 hydraulic powerpack with 72.7 hp Kubota engine pumps hydraulic fluid at up to 43.5 gpm and 4,500 psi. In 50-ton mode the unit directs all hydraulic fluid to just two of the cylinders, which then can move twice as fast as in 100-ton mode.

Although some jobs will require access to the machine’s 100-ton capacity, Goodman said, jobs that require 50 tons of pullback or less mean the actual pipe burst will also be done that much faster.

Pull rod used by the 100XT is the same lightweight 2.5-inch, API-threaded rods used by other models. The spinner assembly incorporated on its carriage is rated to 250 foot-pounds. The spinner allows rod to be fed from behind. As the unit is pushing during payout, rod can be added without stopping the machine. The result is that as the unit is pushing during payout, rod can be made up, or tightened, simultaneously.

Putting the 100XT operator on the surface with remote control frees up workspace in the pit for the rod handler, permits the best view for more efficient control of the operation and also enhances overall worksite safety. Lever-actuated controls on the puller itself facilitate initial training and orientation at the machine and provide redundant backup, ensuring job completion if for any reason the remote control cannot be used.
