hydraulic twin boom jumbo drilling machine,
twin boom jumbo
High efficiency, hydraulic single boom DJ-131 drilling jumbo in underground lead mine
Drilling jumbo is a mining equipment widely used in underground mining if mining is done by drilling and blasting, such as coal, lead and zinc mine. It is also used in tunnel ,culvert tunnelling, railway, highway engineering with advanced hydraulic system and anti-clamping bit device ,the rock drilling rig is a modern equipment of convenient, safe and reliable operation. Equipped with the best international brand drifter, our drilling jumbo can reach 0.8~2m/min drilling speed, and can be applied to 6.1x6.08m tunnel section.
Hydraulic boom with double tripod suspension for accurate hydraulic parallel holding in all directions, direct, fast, easy operation, good accuracy and accurate positioning between holes;
Telescopic boom make up of the angle when drilling the hole of bottom and top, thus no blind angle left.
Rotary actuators with high rotation torque, high load capacity.
International first class drifter with high hardness, high drilling speed, low drilling tool wastage and low failure rate and etc.
Sturdy, articulated carrier with four-wheel drive, powered by diesel engine, high speed and flexible transition improve the working efficiency;
Central lubrication system;
Four jacks for stable set up.
Hydraulically controlled drilling system which incorporates the anti-jamming function rotation pressure controlled feed(RPCF); Impact, rotation and feed adopt separate hydraulic pump, independent control loop ensure ensure the stable power output.
Automatically controlled cable reel;
FOPS telescopic protective roof;
Electrically driven piston compressor.
