The Hydraulic Rotary Rig is a pile drilling equipment that drives the drill rod to rotate and cut the strata through hydraulic power. It is mainly used for large-diameter, deep-hole drilling operations such as building foundations and bridge pile foundations. Its core components include the drill rod, power head, and hydraulic system of the Rotary Piling Rig, which can adapt to various geological conditions such as clay, sandstone, rock formations, etc. Compared with impact drills, this type of equipment has the characteristics of high efficiency, low pollution, and excellent hole quality and is widely used in modern infrastructure projects.

Rotary piling rig application
- Building foundation: large diameter cast-in-place pile construction of high-rise buildings and factory buildings;
- Bridge engineering: ultra-deep pile foundation drilling of cross-river and cross-sea bridges (using Rotary Piling Rig rotary drilling rig);
- Wind power construction: rock formation drilling for wind turbine foundation;
- Municipal engineering: subway station retaining piles and underground continuous wall construction;
- Mining exploration: geological sampling and shaft pre-drilling.
Rotary drilling rig for sale working principle
- Power transmission: The hydraulic system drives the power head to rotate, driving the drill rod and drill bit to cut the formation;
- Drilling control: Apply vertical pressure to the drill bit through the pressure device to improve cutting efficiency;
- Muck discharge: The muck cut by the drill bit is discharged out of the hole with the spiral drill rod or pump suction system.
- Hole wall protection: Use mud wall protection or casing follow-up to prevent hole wall collapse;
- Intelligent adjustment: Some Hydraulic Rotary Rigs are equipped with a formation adaptive system to adjust the speed and pressure in real time.
Advantages of hydraulic rotary rig
- High efficiency and energy saving: the drilling depth can reach 50 meters per day, and the energy consumption is 40% lower than that of an impact drill;
- Environmental protection and low noise: construction noise <75dB, dust pollution is reduced by 80%;
- Accurate hole formation: verticality error ≤1%, aperture deviation ≤5cm (Rotary Drilling Rig for Sale);
- Strong adaptability: various strata can be processed by replacing drill bits (such as cone drills and spiral drills);
- Intelligent control: one-button operation on the touch screen interface, supporting remote fault diagnosis.
