PRODUCT NAME:
ZEGA UJ18 Underground drilling Jumbo
- ZEGA UJ18 drilling jumbo is applicable for narrow & low underground mining tunnel and construction tunnels. Direct control hydraulic system & 4-wheel driven articulated steering is great for rough road conditions & fast approaching & departing from working face. High efficiency drifter is excellent for faster work time & lower tool consumption. UJ18, the best choice for low & narrow underground mining & tunnel conditions.
I. Control system:
Automatic hydraulic drifter control system with auto collaring, percussion auto stop if lack of lubrication and water, auto controlled feeding by rotation pressure and auto controlled percussion by feed pressure, and auto anti-jamming.
Dual speed tramming, auto slowing down and torque output increase to prevent engine from stopping if overloaded while climbing.II. Multiple coordinate boom
Double triangle floating support boom for accurate hydraulic parallel holding of the boom in all directions.IIIFeed beam:
Heavy duty aluminum alloy feed beam with great bending and torsion resistance for long service life.The beam surface covered by stainless steel wrapper and lined by synthetic wear resistant pads between moving parts for longer service life.IV. Drifter:
ZY104M drifter with Dual buffering for longer service life of drill tools.Pressurized oil protection film and full lubrication to reduce internal wear and tear of the drifter.V. Chassis
Strong articulated and heavy duty chassis with four-wheel drive.Driven by 4-cylinder diesel engine.Four hydraulic jacks for stable positioning.
Dual circuit pedal brake system with emergency stop control for safe braking when one side oil pipe or even both damaged. -
