New HDD Designed for Optimum Performance

摘要

Ditch Witch has expanded its line of horizontal direction drills (HDD) with the recent addition of the model JT40. The design philosophy behind the JT40, says Ditch Witch, is "to equip utility contractors with the latest technology for optimal drilling productivity." According to the company, the JT40 is designed with "next-generation enhancements" that include several patent-pending features that promote productivity and operator comfort. The JT40 is compact, reducing its job-site footprint, says Ditch Witch, and the new model has increased pipe-rack capacity, compared with previous models. With an overall length of 290 inches, the 160-horsepower (gross), Cummins-powered JT40 features thrust/pullback forces of 40,000 pounds, 5,500 lb.-ft. of spindle torque from a two-speed drive system, maximum spindle speed of 225 rpm, and carriage speeds of 180 fpm for both thrust and pullback.
