Features

ZLJ-3300 drill rig has many (8) rotation speed gears and reasonable rotation speed range (the highest is 1000r/min and the lowest is 53r/min) and torque is larger at low speed. This drilling rig has wide applications.
It has two gear reverse speeds (45r/min, 212r/min), which is convenient for accident treatment.
It has long vertical feed stroke of 560mm, 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.
It adopts dual oil pump to supply oil with less power consumption and the oil temperature of hydraulic system is lower.
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 rational layout so the operation is flexible and reliable.
In addition to high-speed drilling, ZLJ-3300 drill rig can also be used for low-speed large borehole drilling.
In addition to normally-closed hydraulic upper chuck, ZLJ-3300 drill rig is also equipped with mechanical manual lower chuck.
