DFJ-1W24 Single Boom Underground Jumbo Drills for Mining/Tunneling
DFJ-1W24 jumbo drill apply to mining and tunneling, such as metal mine, hydro-power tunnel, railway, Highway national defense and other underground areas. Hydraulically controlled with one boom.

Product Application

DFJ-1W24 jumbo drill is applied to mining and tunneling, such as metal mine, hydro-power tunnel, railway, Highway national defense and other underground areas. 

1. Wheel single boom drilling jumbo can apply to the excavation drilling in the mining, hydro-power tunnel, railway, road and other underground tunnels. it is full hydraulic drilling and traveling with diesel engine

2. The hydraulic parallel holding can make sure the hold depth and space between, and improve the quality of blasting

3. Telescopic boom can make up of the angle when drill the hole of bottom, thus no blind angle left

4. The standard configuration with imported drifter and rotary actuators, stable performance and high efficiency.

5. The hinge of heave-duty chassis, diesel engine four-wheel drive high traveling speed for transitions. the diesel engine and drive axle are international brand, double brakes for traveling and emergency braking.

6. The cable reel can save the labor and improve the safety.

Drill speed could reach 0.8-2m/min and diesel engine drive the tyre-carrier Travel, the traveling speed can reach 6.5km/h. Wheel type carrier can realize flexible traveling, fast movement forward and backward

8. Special hydraulic boom with double Tripod suspension for accurate hydraulic parallel holding in all directions.

9. The system automatically stop compact at destination, with functions of anti-jamming, water mist Flushing, easy operation, safe and reliable.
