Product Description
Electric motor diesel engine power Down the hole drilling rig KG420S KG420SH limestone cement quarry dust collection splined Axial piston Motor pump steering
Please note, KG420S and KG420SH need separated diesel portable compressors supplying compressed air, 13-18 m3/min at 13-18 bar. ( 460 - 636 cfm 189 - 250 psi 1.3-1.8 Mpa)
Features,
Ultra-reliable Extra long working life, especial for drilling in high levels of dust, high altitude or elevation places
3 m drilling rods / tubes automatically added or unloaded drilling up to 25 m depth for large scale quarry or mine
Main benefits
Low fuel consumption (electric powered drilling available) and high penetration rate
High performance with reliable hydraulic control system,ergonomically designed operator environment,good visibility and hand reach servicability on the ground
Heavy feed and rotation unit designed for any ground condition
Operation friendly for easy drilling and tramming
Main application:
Construction
Aggregate quarries
Open-pit mining
Cement, bluestone and limestone
Quick Facts
Hole diameter: 90-152 mm,
Horizontal hole Height Max. 2850 mm;
Rated hole depth: 25 m ( with drill rod added or unloaded manually)
Engine power(on the rig): 55kW electric motor + 58 kw rating at 2200 rpm YuChai(Cummin optional)
Exact positioning and easy to maintain
The well positioned, manual type swing control panel allows the operator to see the hole clearly and position the rig with precision. The design of the
machine is simple. Main components are conveniently accessible for service and maintenance, when required.
Technical Sepcifications
Matched excavators, haul trucks, crushers etc. could be supplied,
