ZLJ Underground Tunnel Drilling Machine
ZLJ series Geological drill machine is widely used in different angle to exploring water, gas, anti-dust and kinds of construction boring and geological coring drilling.
The drilling machine consists of main frame, gear box, rotary device, winch, band-type brake, hydraulic system, electric system. It adopts mechancial transmission, hydraulic feeding. It is characterized by light weight, compact size, simple structure and easy to maintain.
We also can add the crawler chassis according to actual work condition.
