Description

Z-1250 drill rig is designed for working in narrow spaces, such as tunnel, culver and foundation ditch. With its rotating-percussion rotary head, it is suitable for drilling in stratum formations of sticky clay, sandstone as well as partially decomposed rock stratum. With down-the-hole hammer, it can drill in hard rock formation efficiently. The emission standard of its power engine is TIERIII. With 360 degree horizontal and vertical rotating tables, it can be used efficiently for drilling holes to front facet, flank facet as well as ceiling of tunnels. In the operation panel, there is a special designed operation handle for shifting to grout jetting drilling technique, with suitable rotating and pull back speed for high efficiency grout jetting.
