The wedge principle (Shown on the right) works by adding  power to the A direction, resulting in the power transferred to the B direction to become

even larger. The eventual direction power and splitting distance of B are decided by the counter wedge angle.

Hirado’s Powerful Rock Splitter makes full use of this principle by using the hydraulic pressure to push into the A direction and generate splitting powers up to 3600 ton.

The wedges of the Powerful Rock Splitter are specially designed to endure extreme power and last long. In addition to the standard wedges, customized wedges can be produced as well to suit the needs of the user.

Operation of the Powerful Rock Splitter is simple and it can be attached to a majority of excavators (7 ton+).

Depending on the model, the Powerful Rock Splitter uses 25 or 35MPa of Hydraulic Pressure, which is achieved by connecting the hoses to the excavator connections.

In addition, Hirado’s Powerful Rock Splitter utilizes a unique and innovative valve system. This system ensures that the pressure from the excavator does not need to be calibrated, prevents wear and damage due to overpressure and allows for a simple plug-and-go action to save valuable time.

The Powerful Rock Splitter is efficient, safe, fast and powerful and can be used both vertically and horizontally for a variety of rock splitting work in quarries, open pit construction sites, tunnels and mining.
