Product Details

Main Specification:

1,Rock drill

l ZY104M Thanks to the double buffering, ZY104M rock drill promise good drill steel economy.

l Oil sheet reduces wearing to the mechanical interfaces inside rock drill.

2,Compound coordinate

l Double triangle floating cylinders support accuracy leveling to the boom in all directions.

3,Feed

l Heavy duty alumina alloy feed performs long service life and high strength to bending and distortion.

l Covered by stainless steel coat and lined by synthetic pads for moving parts offer the boom an extension to service life.

4,Control system

l Automatic collaring, lubrication and water subjected percussion, Feeding follows rotation, Percussion follows feeding and auto anti-jamming are inclusive to the function of hydraulic drilling control system.

Dual speed travel forward and backward. Slope automatic adaption by speed decreasing and torque improving prevents engine from extinguishing.

l Simple and reliable circuit and modular segments plus CAN communication compose electric system.

Advantage

1.The most important feature of J21 will privilege mining customers to experience a total different service and low operational cost besides overall superior performance on drilling efficiency, passing ability, stability in various applications.

2. The jumbo patented self-balancing chassis layout design is optimized with oscillation +/-10°on rear shaft to ensure both longitudinal and horizontal safety and stability to 1.7m width chassis at +/-41°turning angle.

3. The high performance drilling with low cost consumables of J21 is very much comparable with even large tunneling jumbos

4. Cylinder wire type full automatic paralleling aluminum alloy feed guarantee stability and precision of drilling with its rigid shape and protected wearing pad and sliding steel coat. The improved measuring, flushing, lubrication and rock drill automatic return mechanism promise higher efficiency to rock penetration.
