The Toro DD4045 horizontal directional drill has 40,000 pounds of thrust and pullback, and 4,500 lb.-ft. of rotary torque.
It features a 160-horsepower, Cummins QSB4.5 diesel, liquid-cooled engine and an on-board, infinitely variable drilling fluid pump that delivers a flow of up to 70 gpm.
Open-top vice wrenches provide visibility of the tool joint to allow for faster connections and breakouts. The quad rack and pinion carriage design spreads the carriage load evenly for travel. The carriage gear track is also welded, not bolted, to the frame. The two-speed carriage allows travel up to 140 ft/min.
For hard rock drilling conditions, an air hammer can be easily integrated and controlled from the DD4045's LCD display.
With flexibility to use single- or dual-stick controls while drilling, the DD4045 allows the operator to choose the control style that matches his or her preference. Operators can also choose to use the cruise control feature when back-reaming. The unit is equipped standard with 52 pieces of 10-foot, one-piece forged drill pipe. The pipe basket is also removable, which makes changing pipe or adding pipe for longer bores fast and efficient, Toro says.
