Definition and Function

Pile Breaker:

Definition: A mechanical device specifically designed to cut and remove concrete cast-in-place piles.

Function: Primarily used for swiftly cutting off pile heads in pile foundation projects, adaptable to various pile forms, including cast-in-place and prefabricated piles.

Hydraulic Breaker:

Definition: A highly efficient hydraulic impact vibration machine, often referred to as a hydraulic hammer.

Function: Utilized to break hard materials such as concrete and rock by generating high-speed impact force on the material’s surface.

Structure and Working Principle

Pile Breaker:

Structure: Composed of components such as cylinders, drill rods, and module bodies.

Working Principle: A power source applies pressure to multiple cylinders, which drive the drill rod to squeeze the pile body, effectively cutting off the pile head.

Hydraulic Breaker:

Structure: Consists of a movement mechanism, cylinder body, piston, and drill rod.

Working Principle: Uses high-pressure hydraulic oil as a working medium. The valve control system and cylinder piston system collaborate to move the piston back and forth rapidly, converting hydraulic energy into mechanical energy to deliver strong impacts via the drill rod.

Application Scenarios and Advantages

Pile Breaker:

Application Scenarios: Commonly used in pile foundation construction, and for the maintenance or demolition of infrastructure such as high-speed railway bridges and industrial or civil construction pile foundations.

Advantages: Offers fast cutting speeds, high precision, ease of operation, convenient maintenance, low noise levels, and cost efficiency during construction.

Hydraulic Breaker:

Application Scenarios: Primarily employed for crushing hard materials like concrete and rock, frequently used with excavator loaders or wheel loaders for efficient demolition work.

Advantages: Versatile with the ability to handle multiple working modes and materials; can sometimes replace pile drivers for driving smaller piles, especially in close-proximity pile foundation scenarios.
