Powerful Rotary Head
Cylinder & rope feed mechanism for smooth operation.Nylon slide piece for longer feed Carriage service life.The guide rail is installed in an inclined way,making operation and observations easier.
Strong Heavy Duty Guide Rail
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.
Dry Type Dust Collector
KG420TH with Dust Collector.It is Hydraulic Cyclonic Laminar Flow.Reduce dust & protect workers’ health.Reduce air pollution & protect the atmospheric environment
Diesel Engine
Equipped with the Yuchai four-cylinder engine (China III),Reduce emissions and protect the environment.
Oil Cylinder & Hydraulic System
Optimize oil cylinder,upgrade hydraulic system.The hydraulic cylinder is more reliable, the system flow is increased, and the rotary drilling speed is increased.
Crawler & Walking Hydraulic Motor
The folding frame track and four-wheel drive are adopted; Add track leveling cylinders;Dual-speed tramming plunger hydraulic motor.Low noise, high efficiency, long service-life, high power.
