Hfg-21j Hydraulic Rock Drill for Sale

HFG-21J hydraulic rock drill for sale
 
The Main Features:

Applicable for blast hole drilling of underground mining, tunneling and bolting operation.

Function Configuration:

Equipped with environment friendly diesel engine to drive tramming and positioning, electrical motor to drive drilling operation, the dual power configuration allows the rig for fast maneuverability and zero emission with very low noise level of drilling operation. The rig is also equipped with high efficiency hydraulic drifter and heavy duty floating and steady combo boom drilling system, with high accurate automatic horizontal positioning and 360 rotating function, which allows the rig to finish 35 m2 face drilling coverage in one operation and also can be used for bolting and many other applications.

Tramming:

With high pressure and closed cycle hydraulic system to drive four wheels, for two speed transmission while moving forward and backward. With engine non stop when overloaded and climbing slopes, the rig will automatically adjust to lower speed with higher torque output. The two loop circuitry pedal braking system plus emergency braking device can ensure tramming safety. With only width of 1.65 m of ultra-narrow articulated heavy duty chassis design, the minimum turning radius is 2.8m with 14 degree climbility and tramming speed up to 12 km/h and the rig aims to drill blast holes in underground mines and tunneling excavation as well as bolting operation with professional narrow design in mind.


Control System:

With automatic hole collaring and percussion shutdown function after the drilling procedure completed plus 3 seconds delay to flush the hole bottom, the rig returns automatically to start mode. With AUTO shutdown protection function of the drifter and the rock drill tools, the rig will lubricate the drifter when rock drilling idle and when water flushing on. Advanced combo automatic anti-jamming system can adjust the rotation, feed and percussion pressure automatically according to the rock condition to ensure rock drilling operation always in optimum mode.

Intelligent Technology:

With CAN technology, modular layout of all electric system, and simplified circuitry increase reliability. The display panel in the canopy shows all drilling parameters and running state of the rig with automatic alarms and warnings, and data storage, to allow one man operation easy and trouble shootings simplified.

Product Features:

1.Feed: Heavy duty aluminum alloy feed beam with high anti-bending and torsion-resistant features and high corrosion proof assures long beam service life. The beam surface also is wrapped with stainless steel sheet and PTFE anti-wear lining applied between moving parts to further increase service life of the feed system.
2.Rock Drill: HF104M drifter with dual-damping system ensures best rock drilling tools service life. Pressurized oil film protects and lubricates all moving parts surface, decreasing interior wear of the drifter.
3.Safety Canopy: FOPS design for falling objects protection with lifting feature.
4.Large-capacity Cable Reel: Larger-capacity cable reel for 70 m travel without cable disassemble.
5.Positioning legs: Four heavy duty telescopic hydraulic legs for precise positioning and stability during drilling operation.
6.Console: Highly integrated System and one place layout design for easier, simpler and more convenient operation.
7. Braking system: Designed and developed specially for underground work environment - the dual braking system, besides front and rear axle wheel wet brakes, with front axle spindle wet brakes and rear axle closed hydraulic parking brakes and emergency shutdown brake added.
