The main feature of the winch pressurized rotary drilling rig is the rotary drive’s longpressurization stroke, capable of uniformly pressurizing a casing over ten meters in length.followed by driling and pile pouring.It can provide comprehensive construction solutions forcomplex geological conditions such as underground rivers and karst caves;

High power, high displacement, high torque, and high pressure provide strong power for productsin large-diameter pile holes, hard rock, and deep pile construction; A solid and stable designconcept allows for strong power to be unleashed; The powerful lifting ability of the main winchensures the safety and efficiency of drilling tool lifting during the construction of large piles;
