Electric stone splitting machine YG series

Product Overview
Hydraulic rock splitter for controlled non-blasting fragmentation of hard rock and boulders. Supplied in three wedge lengths to adapt to hole depth and target split. Suitable for urban excavation, trenching and secondary breaking in mining where blasting or noise is restricted.

Tip
Choose the diesel-driven pump station for remote sites or locations without reliable electrical supply. Diesel units enable mobile operation and reduce dependency on external power.

Why it works

• Massive force: High-pressure hydraulics drive the center wedge outward, producing large tensile forces that split rock from within.
• Simple principle: Rock has low tensile strength; applying a wedge force exploits this to create controlled fractures.
• Complete technical support: Documentation covers correct hole diameter, drilling depth and step-by-step operation to ensure consistent results.

Field Results / Case Study
A contractor working in a residential area in California used a diesel pump station and multiple hydraulic splitter guns to remove large granite boulders where blasting was prohibited. Correct hole preparation and coordinated splitting allowed rapid removal, reduced onsite time and lowered labor and rental costs compared with jackhammers.

Markets & Typical Applications
Non-blasting rock breaking in urban excavation, trench works, landscaping, controlled secondary fragmentation in mining and quarries where noise or blasting restrictions apply.
