DZ300 full hydraulic water well drilling rig

The rig can be used in DTH drilling work. Lifting the drilling rig, drill pipe loading and unloading, turning and feeding, legs, winch, walking and other movements are all operated by the hydraulic system, which significantly reduced labor intensity, improve construction efficiency and quality of the project. 1.hydraulic system from the diesel engine, electric motor to provide strong impetus dual role, the user can freely switch according to site conditions, to meet customers requirements in different conditions of use. 2.high quality DTH drilling is to provide air and displace waste by the air compressor , a variety of operating impactor, drill bits can be equipped according to pore size can be equipped with 3.walking is on their own track-type structure, easy to move. Crawler chassis, steel track plates. 4.drilling and lifting adopt oil tank & chain structure, it is safe and reliable. drilling speed can be adjusted according to different working conditions, improve the efficiency of the footage. 5.hydraulic system is equipped with separate hydraulic oil cooler to ensure that drilling job can go on in high temperature. 6.lifting hoist can lift 0.8 tons of drilling devices flexibly. 7.4 hydraulic leveling jacks can adjust the rig to be level fast. 8.frame can be fixed with the rig body when rig is working, which can drilling, ensure job stability. uniquely designed drill-centering device, combined with the level meter to ensure the accuracy of drilling rigs and drilling the hole verticality. Centering device is very easy to use. 9.special Lubricator compressed air systems can effectively improve the impactor’s life. 10.self-compensated protection can protect drill pipe thread to extend the using life of drill pipe. 11.gas seal structure is unique, it has good sealing effect and durability. 12.roller slide is strong and has a long life.
