TheJL590-3 crawler hydraulic DTH driling rig is equipped with a Yuchai four-cylinder engine, with a light and durablestructure, easy operation and low maintenance cost. it is specially designed for scenes such as quarries, open-pit coal minescement mines, etc. lt can efficiently complete blasting holes and pre-spliting hole driling operations. lt has the advantages offast driling, large diameter and strong adaptability. t is widely used in building materials, coal, metallurgy, chemical industry,as well as construction, hydropower, ransportation, national defense and other engineering fields. lt is the main equipment inefficient mining and engineering construction.

QY series water well driling rig is a light, efficient and multifunctional drilling equipment. lt is mainly used for driling wateiwells, aqricultural irigation wells and other wells, especially for water proiects in mountainous areas and rock formations. Thedriling rig adopts new hydraulic technology, equipped with large torgue hydraulic rotaion motors and a large-diameterhydraulic cylinder for propulsion and lifting. lt is equipped with ordinary alloy dril bits and other driling tools for rotary drling:conventional ball tooth dril bits are used in hard rock formations for impact rotary driling and high-speed hole formation. inunstable formations such as aravel laver, workers can use DTH hammer with following casing.
