Features of DFJ-2W100 WheelUndergroundDrilling Jumbo for Mining/Tunneling etc.
1. Hydraulicboom a. 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. b. Telescopic boom make up of the angle when drilling the hole of
bottom and top, thus no blind angle left. c. America HELAC rotary actuators with high rotation torque, high
load capacity, no position shift, Compact, good anti-pollution
capacity, Heavy-duty and etc.
2. Rock drill France Montabert rock drill with high hardness, high drilling
speed, low drilling tool wastage, low failure rate and etc.
3. Hydraulic feed a. Heavy-duty aluminum feed with high bending and torsional
resistance for maximum durability. b. Snap-on stainless steel sleeves & polymer contacts.
4. Carrier Sturdy, articulated carrier with four-wheeldrive powered by diesel engine, high speedand flexible transition improved the working efficiency; power
steering; Both service brakes and Emergency system brakes; Central
lubrication system; Four jacks for stable set up.
5. Control system 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 the stable power output.
6. General a. Cable reel, control the cable automatic, Save labor and improve the safety. b. Hydraulically driven telescopic protective roof. c. Electrically driven piston compressor.
