- The DKZ-10 drill rig is driven by a frequency conversion motor as the main drive and by hydraulic transmission as the assisting power. This saves energy, reduces costs, and ensures an easy operation. Construction parameters such as rotational speed, rotary torque and power head speed can be displayed and adjusted under different customer requirements.
- All components are on the track chassis. With a simple wireless remote control or operated by workers on the drill rig, it features a self-walk function. .
- It has a long feed stroke of 1700mm with a low disassembly frequency, which increases labor efficiency and decreases labor intensity.
- With a frequency conversion drive, the drill rig is continuously viable according to stratum and slagging, thus avoiding drilling accidents.
- Utilization of a frequency conversion motor and reducer casing for rotation provides a large output torque, thus achieving a constant torque and power operation.. It is continuously viable according to stratum and bore diameter.
- The feed system is driven by an independent frequency converter, and is able to float and hover via a depressed drilling through a winch, wirerope and pulley blocks. Its feeding speed is continuously viable.
- In normal drilling, the hydraulic system has a low power consumption and produces little heat, which ensures the reliability of hydraulic system components.
