In the field of foundation engineering, the Italian SOILMEC SM09 and SM21 drilling rigs are globally recognized for their flexibility and reliability.
The SM09 rig, with its compact design and operational agility, excels in small sites and challenging geological conditions, efficiently handling various small-scale pile foundation projects.
Meanwhile, the SM21 rig, with its higher power and torque output, is ideal for medium to large-scale pile foundation tasks, providing a robust foundation for bridges, skyscrapers, and other major infrastructure projects.
However, as construction standards rise and processes become increasingly complex, the original power heads on these rigs have struggled with large 1.6-meter-diameter mixing piles, often revealing issues such as insufficient power and low efficiency. These challenges hinder the ability to meet demanding schedules and quality expectations.

As a factory specializing in construction machinery for over 20 years, YONDA introduces the 804 high-performance power head retrofit kit, designed to fully unleash the potential of your SM09/SM21 rigs:
▷ Master 1.6m Large-Diameter Mixing Piles: Equipped with four hydraulic motors in parallel drive, the power head delivers up to 63 kNm of torque, effortlessly tackling complex formations such as dense clay and gravel layers.
▷ Four-Speed Gearbox Technology: Adjust to soil resistance with four speed and torque settings ranging from 18-72 rpm and 15-63 kNm, significantly enhancing construction efficiency.
▷ Seamless Retrofit Design: The kit is fully compatible with the original SOILMEC structure, requiring no major modifications to the rig’s main body. This allows for quick installation and commissioning, reducing both retrofit costs and downtime while improving the equipment's cost-efficiency and return on investment.

For those seeking high-performance mixing pile construction equipment, a retrofitted SOILMEC SM09/SM21 rig equipped with the YONDA 804 power head is the ideal choice. It not only revitalizes second-hand equipment but also provides a competitive edge in large-scale infrastructure projects and foundation treatment works. Embrace a new era of efficient and high-quality mixing pile construction.
