In the classification of horizontal directional drilling rigs, this hydraulic type and the pipe jacking of the earth pressure balance type are both very good practices when they are used. When people use them rationally, they can indeed bring better results. Some good advantages, this classification can be better used according to the distinguishing aspects of people’s use, so people can achieve a good effect in this way.
There are many classifications of horizontal directional drilling rigs. Of course, there will be differences in some aspects according to different working locations and working environments. Then when solving such a situation, you can still make good use of this aspect and make better use of it. , Because this advantage is still a very obvious part, when the classification of the attention itself is rationalized, it will be very good to bring better results, the typical classification can be better used, it is indeed a classification In terms of standardized models, good results can be found.
Horizontal directional drilling rigs can be divided into tonnage:
Large drilling rigs with a pullback force of 450 tons-600 tons,
Medium-sized drilling rig, with a drag force of less than 450 tons and greater than 150 tons,
Small drilling rig, the drag force is between 27-150 tons
Horizontal directional drilling rigs are classified according to the walking mode:
Wheel type and crawler type
