When soft soil layers, hard rock formations and tight construction schedules intertwine to form construction challenges, traditional pile foundation construction methods are often inadequate, leading to low efficiency and rising costs. The solution for modern engineering lies in a key technological upgrade — the adoption of rotary piling machine. Taking the YG-30 model as an example, this article will analyze how it has become a core tool for overcoming complex geology and ensuring the on-time and high-quality delivery of projects.【WhatsApp/WeChat/Phone】+86 13837122632
Compared with traditional construction methods, the modern rotary piling machine has achieved a qualitative leap, and its value is reflected in multiple dimensions:
High Construction Efficiency and Precision: From positioning, drilling to hole forming, the process is highly mechanized and standardized, with fast hole forming speed and precise control of verticality and hole diameter, laying a perfect foundation for subsequent construction procedures.
Excellent Stratum Adaptability: By adjusting the power head between “high-speed low-torque” and “low-speed high-torque” modes and adapting different drilling tools, it can easily handle a variety of complex geological conditions ranging from soft soil, sandy gravel to soft rock.
High Safety and Automation Level: The safety control technology based on main winch lifting force detection and bottom contact protection functions have greatly improved construction safety. Operators can complete most operations in the cab with low labor intensity.

Rotary Piling Machine Working Process Analysis
An efficient hydraulic rotary rig follows rigorous construction logic:
Positioning and Preparation: Move the equipment to the pile position, level it through hydraulic outriggers and luffing mechanisms, and accurately align it with the hole position to ensure the verticality of the mast.
Drilling and Soil Extraction: The power head drives the drill pipe to rotate, while the pressurization system provides downward pressure. The drill bucket cuts the soil layer and collects soil residue. After being fully loaded, the main winch lifts the drill bucket at high speed (up to 70m/min).
Slag Discharging and Hole Forming: Move the drill bucket to the soil unloading area through the slewing mechanism and open the bucket door to discharge slag. Repeat this cycle until reaching the designed depth, and finally conduct hole cleaning and quality inspection to prepare for concrete pouring.
The technical details of the YG-30 equipment fully embody the design essence of modern hydraulic rotary piling rig:
Powerful Power and Transmission System: Equipped with a Cummins 154KW engine, it provides sufficient power for the hydraulic system; the maximum output torque of the power head reaches 100kN.m, combined with dual-mode variable speed, ensuring powerful drilling performance.
Stable and Efficient Winch and Pressurization System: The main winch with single-layer rope arrangement features fast lowering speed and effective rope disorder prevention. The long-stroke winch pressurization system provides a maximum pressing force of 110kN, which is especially suitable for complex working conditions requiring casing installation.
Stable and Flexible Chassis and Luffing Mechanism: The high-strength chassis is equipped with a large-diameter slewing bearing, boasting strong load-bearing capacity. The large triangular or parallelogram luffing mechanism ensures stability during operation and flexibility in positioning.
