The screw pile driver adopts hydraulic drive technology, drives the spiral drill rod to rotate through the power head, and gradually screws the pile body into the ground. This construction method does not require the violent vibration of traditional piling and reduces the impact on the surrounding environment. It is especially suitable for urban residential areas or geologically sensitive areas. As an industry-leading manufacturer, YG’s pile drivers are equipped with high-precision hydraulic control systems that can accurately control the drilling depth and torque to ensure that the vertical error of the pile foundation is less than 1%.

Pile driver machine application scope
The screw pile driver is highly adaptable and covers the following main fields:
- Construction engineering: used for house foundations, bridge supports, high-rise building pile foundations, etc., especially suitable for complex geological conditions such as soft soil and sandy soil.
- Energy infrastructure: In photovoltaic power stations and wind farms, photovoltaic brackets and wind power foundation piles can be quickly installed, and construction efficiency can be increased by more than 30%.
- Traffic engineering: Pile foundation construction of highway guardrails, railway signal towers, and port terminals can be operated flexibly in narrow spaces.
- Municipal engineering: The foundation of street lamp poles, billboards, and temporary buildings is fixed, and no large machinery is required to enter the site, saving costs.
Features of hydraulic pile driver
- Advantages of the hydraulic system: YG spiral pile driver adopts full hydraulic drive (hydraulic pile driver), with stable power output and torque up to 27kN・m, which can adapt to soils of different hardness. The hydraulic legs and slewing mechanism support 360° rotation, precise positioning, and reduce manual adjustment time.
- Environmental protection and energy saving: The construction process is noise-free and vibration-free, which meets the requirements of urban environmental protection. Compared with traditional pile drivers, energy consumption is reduced by 40%, reducing carbon emissions.
- Intelligent control: Equipped with a digital instrument panel, it displays parameters such as drilling depth, torque, and oil pressure in real time. The operator can complete the settings through the touch screen to reduce the difficulty of operation.
- Modular design: YG products support the rapid replacement of drill rods and drill bits, adapt to different hole diameters of φ150-800mm, and meet diverse construction scenarios.
Spiral pile driver working principle
- Positioning stage: The hydraulic legs stably support the pile driver, adjust the position of the drill rod through the slewing mechanism, and align it with the pile position.
- Drilling stage: The power head drives the spiral drill rod to rotate at high speed (the speed can reach 62r/min), the spiral blade cuts into the soil, and the torque is used to screw the pile body into the ground. The soil rises and is discharged along the spiral blade to form a complete pile hole.
- Pile formation stage: After the drill rod reaches the designed depth, the hydraulic system rotates in the opposite direction to pull out the drill rod, and the pile body remains firmly underground. If grouting is required, concrete can be injected through the center tube of the drill rod to increase the bearing capacity of the pile foundation.
