- ZLJ-650 drilling rig has 3 gears of rotation speed and torque is larger at low speed, so it has wide applications.
- It has long vertical feed stroke of 400mm, which is helpful to increase drilling efficiency and reduce drill plugging and drill burning accidents.
- Drilling is smooth and stable and fixing is simple. High-speed drilling has good stability.
- Drilling pressure gauge and hydraulic pressure gauge are combined together and oil shockproof structure is adopted. This gauge has simple drilling pressure graduation, accurate indication and long service life.
- It has less control handles and the operation is flexible and reliable.
- ZLJ-650 drilling rig is designed with advanced structure and rational layout and it's convenient for maintenance and repair.
- ZLJ-650 drilling rig has small size, light weight and good dismountability so that it's convenient for moving and transporting.
