Classification

According to the characteristics of the rig, the classification method of the rig is also different. Here are two points:

1. DTH drilling rigs can be divided into two categories: downhole and open air, depending on the location of use. Downhole downhole drilling rigs can be divided into self-propelled and non-self-propelled according to the presence or absence of the traveling mechanism; there are many open-air DTH drilling rigs in China, mostly self-propelled.

2. According to the different apertures, the down-the-hole drilling rig can be divided into light-drilling boring machine (80~100mm aperture), medium-sized down-the-hole drilling rig (aperture 130~180mm), heavy-duty down-hole drilling rig (aperture 180~250mm)
