240 kJ Impact Energy · 16,000 kg Drop Weight · 5-9 m Effective Depth
HC240 complete machine overview
16-ton drop hammer delivering 240kJ impacts, compaction depth exceeding 5m — solving factory foundation settlement issues
On-site footage of Rapid Impact Compaction (RIC) factory foundation improvement. The depth of each impact crater visually demonstrates the magnitude of natural settlement that would occur without proper ground treatment.
At only 7 meters working height, it operates efficiently inside factory buildings — highly mobile, flexible, and ideal for confined industrial environments.
Complete HC240 technical data — core parameters, dimensions, hydraulic system requirements
With powerful impact energy and deep compaction capability, HC240 is widely used across large-scale foundation projects
Deep compaction of embankments over 10m, breaking oversized stones and reducing soil porosity for dense, stable deep layers
Factory ground foundation improvement, solving natural settlement issues and ensuring safe operation of heavy equipment

With outstanding performance and reliability, HC240 is the go-to choice for large-scale foundation engineering projects
16-ton drop hammer with 240kJ impact energy penetrates deep soil layers effectively. Shock waves travel over 5 meters — ideal for high-fill and deep soft soil compaction.
At just 7.613m working height, HC240 operates efficiently inside factory buildings and under bridges — far more adaptable than large dynamic compaction machines.
31.5 MPa high-pressure hydraulic system with integrated accumulator, filter, and overload protection. Auto-stop on overload — stable, reliable, easy to maintain.
Attaches to 70t+ excavator front via special flange connection. Quick to install and remove. One carrier machine handles multiple attachment tools — lower total equipment cost.
Overload protection, buffer locking, and emergency stop are all integrated. The professional control system provides automatic protection under abnormal conditions.
Large-area compaction completed efficiently per hour. Layer-by-layer compaction with real-time compaction monitoring. Quality is controllable and traceable.
Four-step standardized workflow ensures consistent compaction quality every time
Position excavator on level ground; connect HC240 hydraulic lines and control cables
Move HC240 to work area; adjust so the compaction plate contacts the ground level
Start the hydraulic compaction program; apply designed number of blows per lift
Verify compaction density; move to next point and repeat until area is complete
Answers to the most common questions about HC240 hydraulic impact hammers
The HC240 is ideal for deep compaction of high-fill embankments, factory foundation reinforcement, soil-rock fill areas, dam reinforcement, and bridge abutment backfill — any project requiring 5-9m effective compaction depth.
The HC240 requires a 70-ton or larger excavator as the carrier. It needs approximately 600 L/min hydraulic flow and 31.5 MPa hydraulic pressure. Verify excavator hydraulics match HC240 requirements.
HC240 delivers 240kJ impact energy (vs 150kJ), 16,000kg drop weight (vs 10,000kg), 5-9m effective depth (vs 4-8m), and weighs 28.9t (vs 21.5t). HC240 is built for deeper, heavier compaction tasks.
Yes. With a working height of just 7.613m, the HC240 operates efficiently inside factory buildings. Its compact design and excellent mobility make it ideal for confined industrial environments.
Compaction quality can be verified through density tests (sand cone / nuclear gauge), plate load tests, and settlement observation. A test section is recommended before full production to determine optimal blows per layer.
Ensure ground bearing capacity supports the machine weight, keep the compaction plate level, limit lift thickness to 1.5-2.5m per layer, and monitor vibration impact on nearby structures during operation.
