New Underwater Hydraulic Breaker

Underwater construction is becoming increasingly safe and precise, while also requiring environmentally friendly practices.

 Our new underwater hydraulic breaker is designed for non-explosive underwater demolition, making it ideal for port maintenance, marine restoration, bridge pier repair, seabed trenching, 

and controlled rock removal around foundations.

This next-generation breaker features a high blow frequency and concentrated impact force, effectively breaking rock while minimizing impact transmission and environmental disturbance.

Key Specifications

Impact Frequency: 90-120 times per minute

Chisel (Rod) Diameter: 235 mm

Impact Force: Up to 51,586 lbs (as specified by the customer)

Operating Environment: Fully submersible (suitable for saltwater and freshwater)

Mounting Method: Compatible with amphibious excavator and crane hydraulic systems

Key Features and Benefits

1. High-Frequency Impact for Fast Demolition

This breaker delivers 90-120 impacts per minute, repeatedly impacting the rock to fatigue and break it down. This allows for faster demolition than conventional breakers, reducing on-site construction time and vessel operating costs.

2. Large Chisel Diameter for Deep Crack Propagation

The 235mm chisel concentrates energy into a narrow area, effectively initiating and propagating cracks in hard rock.

3. Powerful Impact Force

Rated at up to 51586 impact forces, it delivers the powerful force required for demanding underwater demolition, while the high-frequency impact ensures continuous demolition rather than a single, powerful blow.

4. Non-Explosive (Controlled) Demolition

This breaker avoids the use of explosives and the associated permitting, safety zone, and environmental impacts of blasting. It enables precise demolition in sensitive environments such as docks, pipelines, and densely populated shoreline projects.

5. Reduced Acoustic and Vibration Impact

The design minimizes transmitted vibration and acoustic shock, reducing the risk to nearby marine life and structures compared to traditional blasting.

6. Robust Marine Structure

The design is corrosion-resistant, pressure-sealed, and designed for long-term operation in both saltwater and freshwater environments.

Typical Applications

Port and wharf maintenance

Dredging and construction in densely populated areas

Bridge pier and pile foundation repair and removal

Underwater concrete removal and cofferdam decommissioning

Offshore wind turbine foundation preparation and repair

Dredging support requiring precise rock removal

Installation and Operation Precautions

Loader Compatibility: Match the hydraulic flow and pressure to the rated range of the breaker. We provide a compatibility checklist for common underwater excavator models and crane-mounted hydraulic systems.

Environmental Monitoring: Before operation, conduct baseline turbidity and acoustic monitoring as required by regulatory agencies. Real-time monitoring helps minimize environmental impact.

Maintenance: Regularly inspect seals, chisels, and internal valves to prevent seal damage caused by improper construction practices and external rock damage during operation to extend service life. Spare chisels and a basic seal kit should be kept on site.
