Horizontal direction drill Machine DDW-250
DDW-250C drilling rig is designed as integral rubber tracked drive with self-powered function which is featured as convenient transportation and flexible movement. The drilling rig adopts rack and pinion for feeding and pull back which has high efficiency and reliable performance, also convenient for maintain. Low speed but big torque cycloid motor for rotary, pullback is drived by piston motor and reducer, famous brand hydraulic pump and motor supplied from American invested company, in order to supply reiable performance, the hydraulic components we use are all supplied by the best manufacturer in domestic and abroad. The control consoles can be rotary to have the best review. Closed operating cab could equipped with air conditioning, which is comfortable for operator, use pipe loader to reducce the intensity of labor, work efficiency.
