Product Description

Product Description

A hydraulic breaker is a high-performance demolition attachment designed for excavators, backhoes and skid steer loaders. This robust tool utilizes the host machine's hydraulic system to deliver powerful, repetitive impact forces for breaking rock, concrete and other rigid materials in construction, mining and demolition applications.

Key Specifications:

• Impact Energy Range: 500-15,000 Joules

• Operating Weight: 50-5,000 kg

• Working Pressure: 100-180 bar (1,450-2,600 psi)

• Required Oil Flow: 20-300 L/min (5-80 GPM)

• Blow Frequency: 300-1,500 blows per minute

• Tool Diameter: 50-200 mm (standard chisel sizes)

The hydraulic breaker consists of three main components:

1. Housing - High-grade steel construction with reinforced design

2. Impact Mechanism - Nitrogen-charged accumulator and piston system

3. Tool Bits - Replaceable chisels (moil, blunt, flat types)

Operating Principle:
The breaker converts hydraulic energy from the carrier machine into mechanical impact force through a reciprocating piston. When activated, high-pressure oil drives the piston to strike the tool bit, which transmits the energy to the work material. The nitrogen accumulator stores energy for consistent performance.

Performance Advantages:

• 30-50% faster breaking than conventional methods

• Reduced noise/vibration compared to explosive demolition

• Precision breaking capability for selective demolition

• Minimal maintenance requirements (seal replacement every 2,000 hours)

• Compatible with all major excavator brands (CAT, Komatsu, Volvo etc.)

Typical Applications:

• Foundation demolition in urban areas

• Secondary rock breaking in quarries

• Trenching through hard strata

• Concrete structure dismantling

• Frozen ground breaking

Selection Considerations:

1. Match breaker size to carrier machine weight

2. Verify hydraulic flow/pressure compatibility

3. Select appropriate tool bit for material type

4. Consider automatic lubrication systems for intensive use

Maintenance Requirements:

• Daily inspection of mounting pins/bushings

• Regular nitrogen pressure checks

• Timely tool bit rotation/replacement

• Hydraulic filter changes per manufacturer schedule

Leading manufacturers include Atlas Copco, Montabert, Furukawa, and with models available for machines from 1-100 ton classes. Proper selection and operation can achieve 10,000+ working hours service life.

The hydraulic breaker, also known as the demolition hammer, is a powerful construction tool used for breaking apart concrete, asphalt, rocks, and other hard materials. Equipped with a heavy-duty piston that operates within a steel housing, it harnesses the hydraulic power of excavators or loaders to deliver rapid, repeated impacts. Its design ensures high-efficiency demolition, reducing manual labor and accelerating construction or demolition projects. The breaker's versatility allows it to be adapted to various sizes and applications, from light-duty jobs to heavy-duty demolitions, making it an indispensable asset in the construction and mining industries.
