XY-44A is a modified and improved deep/middle-hole core drill rig, with complete functions and stable performances. It can be used to not only the big/small-diameter core drilling with carbide & diamond bits, but also the engineering construction in such fields as engineering geological exploration, building engineering, hydropower, highway, railway and harbor construction, etc. This machine is characterized by rational structure, light in weight, powerful capacity, as well as the standardized components and high unification for product series.
