The HammerHead HydroGuide HG1200 winch is designed to be more efficient and easy to use in pipe bursting, sliplining and slitting applications. The unit has a hydraulic downrigger that automatically deploys the boom downhole and can fine-tune the depth up to 18 feet. It also has precision controls for line speed, from 0 to 111 feet per minute, and pressure, from 0.5 to 12 tons. A Tier 4 Kubota D1105 four-cycle diesel engine provides power, and a radial piston motor provides consistent pulling power. 800/331-6653; www.hammerheadtrenchless.com.
