HYDRAULIC DRILLDRILLING RIG TOP HEAD DRIVE DTH AND MUD HIGH TORQUE

Product selling points

The drilling depth is 200-2000m, and the hole diameter covers 100-2000mm.

Full hydraulic control is convenient and flexible

The rotating speed, torque, propulsive axial pressure, counter axial pressure, propulsive speed and hoisting speed of the drilling rig can be adjusted at any time to meet the requirements of different drilling tool operating conditions and different construction processes

Top drive rotary propulsion lift

It is convenient for the connection and unloading of drill pipe, shortens the auxiliary time, and is also conducive to the following pipe drilling.

Multifunctional drilling

All kinds of drilling techniques can be used in this kind of drilling machine, such as down hole drilling, through air reverse circulation drilling, air lift reverse circulation drilling, cutting drilling, roller drilling, pipe following drilling and core drilling under development. The drilling machine can install mud pump, foam pump and generator according to the needs of users. The rig is also equipped with various winches as standard.

High efficiency

Due to the full hydraulic and top drive rotary propulsion and lifting, it is suitable for various drilling processes and various drilling tools, with convenient and flexible operation, fast drilling speed and short auxiliary time, so the operation efficiency is high.

Low cost

In rock drilling, DTH hammer drilling technology is the main one, which has high efficiency and low cost.

High leg crawler type

High outrigger is convenient for loading and transportation, and can be loaded directly without crane. Crawler walking is more suitable for muddy field movement.

Positive and negative axial pressure adjustment

The best impact efficiency of all kinds of impactors has the best axial pressure and rotation speed. In the process of drilling, with the increasing number of drill pipes, the axial pressure of the impactor is also increasing. Therefore, in the construction, the positive and negative axial pressure valves are adjusted to ensure that the impactor can obtain more matching axial pressure. At this time, the impact efficiency is higher.
