The drilling machine is driven by diesel engine, and rotary head is equipped with international brand low-speed and large-torque motor and gear reducer, feeding system is adopted with advanced motor -chain mechanism and adjusted by double speed. Rotating and feeding system are controlled by hydraulic pilot control which can achieve step-less speed regulation. Breaking out and in drill rod, leveling the whole machine, winch and other auxiliary actions are controlled by hydraulic system. The structure of rig is designed to reasonable, which is easy to operate and maintenance.
Key Features & Advantages
1. Full Hydraulic Control
The speed, torque, thrust axial pressure, reverse axial pressure, thrust speed and lifting speed of the drilling rig can be adjusted at any time to meet the requirements of different drilling conditions and different construction technologies.
2. Top Drive Rotary Propulsion
It is convenient to take over and unload the drill pipe, shorten the auxiliary time, and is also conducive to follow-up drilling.
3. Multi-Function Drilling
All kinds of drilling techniques can be used, such as DTH, air/mud reverse circulation, cutting, cone, and pipe following drilling. It can install mud pump, foam pump, generator, and hoists based on client needs.
4. High Efficiency & Low Cost
Due to full hydraulic drive and top drive rotary propulsion, it has fast drilling speed and short auxiliary time. The down the hole hammer drilling technology in rock ensures high operation efficiency and lower single meter cost.
5. High Leg Crawler Chassis
The high outrigger is convenient for loading and transportation, allowing direct loading without a crane. Crawler walking is exceptionally suited for movement in muddy fields.
6. Oil Mist Eliminator
Equipped with an efficient and durable oil mist device and pump, ensuring that the high-speed running impactor is lubricated constantly to significantly extend its service life.
7. Adjustable Axial Pressure
Positive and negative axial pressure valves can be adjusted to ensure that the impactor obtains optimal matching pressure as drill pipe weight increases, maintaining higher impact efficiency.
8. Optional Rig Chassis
To fit different transport scenarios, the drilling rig chassis can be optionally mounted on crawler chassis, truck chassis, or trailer chassis.
