double hoists set, large module, hyperboloid turntable, large torque, so it is easy to operate. CYT-400 engineering and water-well drilling rig adopts large gantry frame which up and down is controlled by mechanical system, double hoist set, large module, hyperboloid turntable, large torque and easy to operate. This type of driller is used in construction of high-rise building, highway and road, ports, dams and large-diameter borehole piles and deep well drilling.
