Simple Maintenance Trailer Mounted Drilling Rig Fast Transition Narrow Road Access
Tire type Trailer Mounted Drilling Rig is a small and medium-sized drilling equipment with a four-wheel trailer/self-propelled tire chassis as the walking mechanism. It is divided into three types: traction wheel, four-wheel self-propelled wheel, and car mounted wheel. It relies on diesel power and supports two drilling processes: mud rotation and impact down the hole drilling. It is mainly used for shallow, medium, and deep well water intake construction.
