Top 100: New Tool for Pipe Bursting

HB80 HydroBurst fits between Hammerhead's smaller HB5058 and larger HB125. The static pipe-bursting machine can be used on water, sewer and gas lines from 4 to 12 inches. It has 80 tons of pulling force and weighs 3,060 pounds for ease of transport. Rod design allows for a positive grip to the rod and eliminates jaw slippage. A spinner eliminates the need to hand-spin rods, and a set of vices torque the rods together to form a uniform rod string. Estimated list price: $110,000 to $145,000.
