Features

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.
