Hydraulic rock splitter HRB-1000

The Yamamoto Hydraulic Rock Splitter is a powerful and efficient tool designed for blast-free rock removal and hard rock excavation. While explosives remain a common method for breaking rock, increasing regulations and safety concerns—such as vibrations, flyrock, and noise—have led to strict restrictions or complete bans on blasting, especially in densely populated or sensitive areas. The Yamamoto Rock Splitter provides a safe and hydraulic-powered alternative to traditional blasting. Based on the wedge and feather principle, it utilizes hydraulic force to split the rock instead of relying on impact or explosives. This makes it an ideal solution for blast-free mining, rock splitting, and controlled excavation in challenging environments. How Does the Hydraulic Rock Splitter Work? The splitter is typically mounted on a standard excavator, utilizing the carrier’s hydraulic system for operation. However, it can also be adapted to cranes or custom carriers depending on the project’s needs. Thanks to its simple installation, the rock splitting machine can be quickly transferred between different carriers, ensuring flexibility across multiple excavation projects. For large-scale rock excavation in hard rock, no mechanical method is more efficient, safe, and quiet than the Yamamoto Hydraulic Rock Splitter.
