Hydraulic Impact Hammer with High Impact Energy per Blow and Low Noise Eco

The Hydraulic impact hammer HDY22 is the latest generation of energy-saving and environmentally friendly piling equipment from our company. Designed to meet the demanding requirements of foundation construction in Southeast Asia, India, and Russia, the HDY22 combines advanced hydraulic and electrical control technologies to deliver outstanding performance in various geological conditions. Whether you are driving precast concrete piles or steel pipe piles, this hammer provides a perfect balance of power, precision, and sustainability.

With a maximum strike energy of 330 kN·m and a hammer core stroke of 1500 mm, the HDY22 delivers exceptional high impact energy per blow. This characteristic ensures that each strike drives the pile deeper into the ground, reducing the total number of blows required and accelerating project completion. The 22,000 kg striking body mass generates a powerful impulse that easily penetrates dense soils, stiff clay, and even soft rock layers commonly found in Russian and Indian terrains. Contractors working on large-scale infrastructure, port construction, and high-rise building foundations will appreciate the efficiency gained from this high-energy design.

Urban expansion and environmental regulations are increasingly strict across Southeast Asia and India. The HDY22 features low noise eco friendly operation, thanks to its fully enclosed hammer structure and advanced vibration damping system. Noise levels are significantly reduced compared to traditional diesel hammers, allowing daytime and even nighttime work near residential areas without complaints or penalties. Moreover, the hydraulic system eliminates exhaust emissions at the point of use (when paired with an electric power station option), making it a green choice for sensitive environments such as city centers, near schools, hospitals, and ecological zones.

Different soil layers and pile types require different impact strategies. The HDY22 offers adjustable impact frequency control ranging from 20 to 70 blows per minute. Operators can easily dial in the optimal frequency via the electronic control panel, matching the hammer’s output to ground resistance. For soft soils, a lower frequency prevents pile damage; for hard layers, a higher frequency delivers rapid penetration. This flexibility is especially valuable in India and Russia, where site conditions can vary dramatically within a single project. The adjustable frequency also helps avoid resonance with surrounding structures, enhancing safety and precision.

At the heart of the HDY22’s efficiency lies the dual pump flow merging system. The power station (model D550) is equipped with two Rexroth A11VLO series axial piston pumps – one A11VLO260 and one A11VLO190 – operating in parallel. When high flow is demanded during the hammer lifting phase, the dual pump flow merging system combines the output of both pumps to rapidly raise the piston. During the drop phase, the system seamlessly reduces flow to save energy. This intelligent hydraulic management results in faster cycle times, lower fuel consumption (or lower electric power draw), and reduced heat generation. The system also uses internationally renowned components: Rexroth main pumps and valves, Hedrick return filters, and Trelleborg seals, ensuring reliability even in extreme temperatures – from Siberian cold to tropical humidity.

For Southeast Asia (Indonesia, Thailand, Vietnam, Philippines):

• Low noise operation allows work near villages and tourist areas.

• High impact energy per blow reduces piling time in soft to medium soils.

• Dual pump system handles high ambient temperatures with efficient cooling.

For India:

• Adjustable impact frequency control adapts to varied soil strata (black cotton soil, laterite, alluvium).

• Low maintenance cost design (using premium seals and filters) minimizes downtime.

• D550 power station with diesel engine provides reliable power even in remote sites.

For Russia:

• Robust construction and high-quality hydraulic components operate reliably in sub-zero conditions.

• High impact energy per blow drives piles through frozen ground and gravel layers.

• Eco-friendly operation reduces environmental impact in protected natural areas.

The HDY22 Hydraulic impact hammer combines high impact energy per blow, low noise eco friendly operation, adjustable impact frequency control, and a dual pump flow merging system into one reliable machine. Whether you are building highways in India, residential towers in Jakarta, or energy infrastructure in Siberia, the HDY22 delivers faster, quieter, and more efficient pile driving.
