KG520/KG520H Surface Drilling Rig
Features:
Powerful Rotary Head
Cycloid rotation double motor for powerful rotation torque.Bigger and stronger designed rotation head for smooth high torque output and less drill tool jamming with seamless speed regulation.
Strong Heavy Duty Feed Beam
New design positioning system,easier for operation in the worst situation.Cylinder & rope feed mechanism for smooth operation.Nylon slide piece for longer feed beam service life.The guide rail is installed in an inclined way,making operation and observations easier”
Flexible Boom
Multi-directional Drilling Design.For complex drilling conditions,350mm ground clearance for horizontal drilling applications,is suitably qualified for horizontal drilling at a low level.
Hydraulic System
The hydraulic system is upgraded,the hydraulic cylinder is more reliable,the system flow is increased,and the rotary drilling speed is increased
Enlarged Dry Type Dust Collector
KG520H is with Dust Collector.It is Hydraulic Cyclonic Laminar Flow.Reduce dust and protect workers’ health. Reduce air pollution and protect the atmospheric environment.
Diesel Engine
Equipped with the Yuchai four-cylinder engine (China III,Opational:China II), Reduce emissions and protect the environment.
Track Oscillation for better tramming & cross terrain performance”
Construction Steel Crawler
Equipped with speed reduction tramming system and standard excavator track for compact structure.Excellent off-road performance with powerful two-speed hydraulic tramming system for extreme low failure rate.
Control Panel
All controls integrated on the control panel for convenient operation by single operator,higher work efficiency & lower drilling cost,safer and more comfortable operation.
Walking Hydraulic Motor
Dual-speed tramming plunger hydraulic motor.Low noise, high efficiency, long service-life, high power, easy maintenance.
