Open pit multifunctional DTH/RC drill for blasting hole drilling
WITH BUILT-IN AIR COMPRESSOR+ROD MANIPULATOR+CABIN
Dragon GP830 is all-in-one hydraulic DTH drilling rig, which brings you more automation, higher working efficiency,
better reliability and simpler operation. The FOPS-approved cabin and automatic pipe handling system are equipped. Heavy-duty undercarriage with wide tracks ensures its travelling safety while move quickly. Hydraulic dust collecting system meet the latest environmental protection regulations and it is reliable solution to meet the modern green mining.
Features of Dragon GP830 drill rig
♦ Fully automatic drilling, single operator is needed.
♦ Imported REXROTH and EATON hydraulic control components ensure the powerful torque output, meet various medium-big size hole request.
♦ Telescopic heavy-duty drill arm provide bigger fan shape drilling coverage, improve the effective drilling time.
♦ Diesel engine is powerful, impact force, feeding force and rotation speed can be adjusted according to different rock conditions, suitable for various terrains.
♦ Atlas air compressor imported from USA. Working pressure can reach 25bar, displacement can reach 28m3/min, feeding speed is high, and hole forming quality is good.
♦ The EFI Cumins QSZ13 diesel engine offers large power and meets EU stage III emission standard;
♦ Hydraulic rod changer and drilling tool positioning device realize the automatic rod handling.
♦ Hydraulic crawler oscillation mechanism and dual-speed travelling motors.
♦ Air-conditioned cabin with ROPS/FOPS.
♦ Efficient automatic pulse-jet dust collection mechanism.
♦ Dust suction cap could slide up and down.
High efficiency
It is equipped with small electrical air compressor, when start the engine, the small air compressor work firstly to reduce the load on the main air compressor to ensure the engine's smooth start and decrease the starting damage.
Three-degree-freedom, multi-directional drilling arm structure, with an telescopic straight boom, effectively expand the drilling coverage.
Durability
The heavyduty undercarriage is featured of robust structural strength, wide tracks and excellent gradeability, which ensures its stability while travelling and working. It use motor-driven planetary reducer and chain wheel mode, chain's strength is high, working life is long, adjustment is easy.
Convenience
Repair and maintenance are very convenient since that maintenance and check points are easily accessible, engine compartment is well organized, and all service doors can be easily opened and closed.
Drill machine's working data, reminder and alarming are all integrated on the instrument panel, convenient for the operator to control the machine.
Safety
The closed cabin is equipped with aircon, FOPS approved, which meet EU and US safety protection standards. The all around large safety windows offer great visibility to the operation to control the drilling precision. The ground clearance is more than 400mm and suit for various tough terrains, greatly reduce the possibility of collision between chassis and ground.
