YQZ180D Trailer Mounted Drilling Rig is a light, efficient and multi-functional drilling equipment. The drilling rig adopts a two-wheel trailer type, which makes the turnaround convenient and fast. It is mainly suitable for drilling small-bore water wells, ground temperature air-conditioning holes and other wells, especially for water intake projects in mountainous areas and rock formations. The efficiency is more than ten times higher than the traditional rotary drilling rig, and the economic benefits created for users are very considerable. Especially, it solves the construction problem of a rotary drilling rig in hard rock stratum and can work efficiently under various geological structures.
