1. Convenient & Flexible to Operate
Hydraulic drilling rig’s speed, torque, propulsion shaft pressure, countershaft pressure, propulsion speed, lifting speed, and programmed empirical rig parameter matching scheme can be adjusted at any time to meet the needs of different drilling tools and different construction processes.
2. Top-drive Rotary Propulsion
The power head has patented anti-impact design technology. The rotary reducer is reliable and durable, and it is convenient for the drill pipe to be connected and unloaded, shortening the auxiliary time, and is also beneficial for drilling with the pipe.
3. Multi-purpose Drill
Various drilling technology can be used in this kind of drilling machine, such as: drilling through the hole, through air reverse circulation drilling, gas lift reverse circulation drilling, cutting drilling, cone drilling, pipe drilling and core drilling under development and so on. The drilling machine can be equipped with mud pump, foam pump and generator according to the user’s demand. Drilling machines are also equipped with a variety of standard winch.
4. High Working Efficiency
Adapted to various drilling processes and different use environments, the control is convenient and flexible, the drilling speed is fast, and the auxiliary time is short, so the work efficiency is high and the risk of construction accidents is reduced.
5. Low Cost
Drilling on rock is mainly based on the drilling technology of DTH hammer, which is effective in rock drilling high rate, single meter drilling cost is lower. This kind of drilling rig is durable, low failure rate, high reliability, greatly reduce your later maintenance costs.
6. High Leg & Crawler Type
The high-legged legs are easy to load and transport, and can be directly loaded without a crane. Crawler walking is more suitable for muddy on-site movement.
7. Positive and Negative Axial Pressure Adjustment
The optimum impact efficiency of the various impactors has their optimum axial pressure and speed. During the drilling process, as the number of drill pipes increases, the axial pressure on the impactor also increases. Therefore, the positive and negative axial pressure valves are adjusted during construction to ensure that the impactor can obtain a more matching axial pressure. The impact efficiency is the highest at this time.
8. Proprietary Technology of Oil Mist and Oil Mist Pump
Impact on high speed running at all times during drilling lubricate the machine to extend its service life.
9. Drilling Rig Chassis
It can be either a tracked self-propelled chassis or a vehicle-mounted self-propelled chassis or a trailer type chassis.
10.Comparing with Others, the Value of Our Used Rig is Higher
Since the main components of the rig are all imported brands, the main frame of the rig is made of high-quality high-strength low-carbon alloy steel, which increases the overall strength and is super wear-resistant. There is also a heavier hydraulic system, which is very valuable.
