Product Features 1. This type of drilling rig power standard four-cylinder Yuchai YC4D80, motor 45kW, motor 55kW. The standard configuration of three meters 76mm diameter drill pipe or a variety of optional twist drill rod. It is diesel, electric dual-use models, the power switch at any time. 2. Strengthening the strength of each aircraft structural parts, fully bear the original ZGYX-3500 rig the functional requirements. 3. With high torque orbital motors drive double turret, reducing the failure rate and the heavy volume of original ball motor. Greatly strengthened the rig torque (up to 5500N? M), making it more rock pore size range, it can be widely applied in foundation pit anchor, with pipe, large diameter twist drill rod operation. The self-developed high-performance wet-air filter, air filter with a dry form tertiary air filtration systems, better protection of the diesel engine; 5. two-speed rotary valve switching easy to operate, can meet the operational needs of different torque and speed . 6. Strengthening standard travel motor assembly, climbing more powerful, more reliable quality. 7. The high-torque rotary head with high and low speed switching device can be widely used large diameter bolt, with pipes and DTH drilling. 8. Standard strengthen walking motor, more powerful walking, climbing stronger, lower failure rate. Recommendation 1. Compressor program supporting high altitudes: 250SCY-17, ordinary altitudes: 177SCY-17, 191SCY-17 2. Chai shift in air pressure: 178SCY-14.5, 138SCY-14.5,139SCY-14.5,190SCY-16 3 Chai shift high pressure: 177SCY-17,250SCY-19,260SCY-21 4. Power shift in air pressure: 90SDY-14.5,132SDY-13 5. Power shift high pressure: 185SDY-17,200SDY-21 Note: Depending on the pore size and Air line distance matching various types of air compressors.
