Powerful Rotary Head
Big and strong 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 mine drilling rig Design.For complex drilling conditions,325mm ground clearance for horizontal mine drilling rig applications,is suitably qualified for horizontal drilling at alow 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
Control Panel
All controls integrated on the control panel for convenient operation by single operator,higher work efficiency & lower mine drilling rig cost,safer and more comfortable operation.
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.
Diesel Engine
Equipped with the Yuchai six-cylinder engine (China III), Reduce emissions and protect the environment.
KG300GF Open-air photovoltaic drilling rig can be equipped with 1 ton frame winch for feed(optional), convenient for hoisting drill bit and drilling tool,impact device, etc. When used on large slopes, you can choose to use 8-ton frame winch for rig(optional) to ensure sufficient traction when using the drill rig.
Walking Hydraulic Motor
Dual-speed tramming plunger hydraulic motor.Low noise, high efficiency, long service-life, high power, easy maintenance.
