• DKZ-10 drill rig is driven by frequency conversion motor as main drive and by hydraulic transmission as assisting power, saving energy, reducing cost and easy to operate. Construction parameters such as rotational speed, rotary torque and power head speed can be displayed and adjusted under requirements.
• All components are on the track chassis. With wireless remote control or operated by workers on the drill rig, it can realize walk by itself.
• It has long feed stroke of 1700mm with low frequency of disassembly, which can increase labor efficiency and decrease labor intensity.
• With frequency conversion drive, the drill rig is continuously viable according to stratum and slagging, to avoid drilling accidents.
• Utilize frequency conversion motor and reducer casing for rotation to provide large output torque, which can achieve constant torque and constant power operation. It is continuously viable according to stratum and bore diameter.
• The feed system is driven by independent frequency converter, and is able to float and hover by depressed drilling through winch, wirerope and pulley blocks. Its feeding speed is continuously viable.
• In normal drilling, the hydraulic system has low power consumption and produces little heat, which can ensure the reliability of hydraulic system components.
