KT7D Integrated Drilling Rig
Features:
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 Carriage
New design positioning system,easier for operation in the worst
situation.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.
Hydraulic System
The hydraulic system is upgraded,the hydraulic cylinderis more reliable,the system flow is increased,and therotary drilling speed is increased.
Flexible Boom
Multi-directional Drilling Design.For complex drilling conditions,
430mm ground clearance for horizontal drilling applications,is
suitably qualified for horizontal drilling at a low level.
Enlarged Dry Type Dust Collector
It is Hydraulic Cyclonic Laminar Flow.Reduce dust and protect workers’ health. Reduce air pollution and protect the atmospheric environment.
Auto Drill Rod Changer
Rod storage rack and auto changer. High efficient,fast and reliable mechanical rod changer.Clamp type hydraulic handling platform for difference sizes of rod to handle easily.
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 failurerate.
Diesel Engine
Equipped with the Yuchai or Cummins engine (China III), Reduce emissions and protect the environment.
Track Oscillation for better tramming & cross terrain performance
Screw Air compressor
All-in-one surface drilling rig,build in Kaishan screw air compressor 15 m³/min,18bar.
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.
