Hydraulic water well drilling rig introduction

YG-300 hydraulic water well drilling rig

In this article, we take YG-300 hydraulic water well drilling rig from YG Machinery as an example to introduce. YG-300 water well drilling rig is a fully hydraulic drive, power-head drilling rig. It is mainly suitable for the construction of water well drilling rigs and geothermal hole construction. It is also suitable for the construction of large-diameter vertical holes or unloading holes in geotechnical engineering such as hydropower stations, railways, highways, and urban foundations; grouting reinforcement holes; small foundation pile holes; Micro piles and so on. The drilling rig uses a variety of techniques, such as conventional down-the-hole hammer drilling, long auger drilling, mud circulation drilling, follow-up drilling, roller cone drilling, hydraulic hammer drilling, etc. If you want to know more, please click here for more details.

Main feature

● The drilling rig has strong drilling capability, a wide application range, fast drilling speed, strong accident handling ability, and high drilling efficiency.

● The powerhead of the drilling rig can be changed mechanically/hydraulically. Suitable for various drilling methods such as down-the-hole hammer, follow-up pipe, full set of pipe rapid alloy rotation, etc.

● The main shaft adopts a telescopic mechanism, which can effectively protect the drilling tool; the powerhead and the orifice can be reversed to obtain a larger drilling angle.

● The drilling rig is equipped with hydraulic clamping and shackle device or pipe screwing machine, automatic shackle, reducing auxiliary time and labor intensity.

● The drilling rig is mounted on the crawler chassis, which makes the whole machine shift and walk faster and more convenient.

● The main components of the hydraulic system of the drilling rig are made of domestic and foreign famous products so that the performance of the whole machine is stable and reliable, and the service life is long.

● The YG water well drilling machine can be applied to a variety of drilling process methods.

● Spiral drilling without circulating fluid, air down-the-hole hammer drilling, mud positive circulation full-pipe drilling, air down-the-hole hammer and tube drilling, roller cone drilling, etc. There is YG official website you can check if you are ready to contact them.
