A hydraulic rock splitter is a machine for hydraulic rock splitting. It breaks rock and concrete without using blasting. This rock splitter machine is quiet, safe, and makes no dust. It is used in cities, tunnels, and near buildings where blasting is not allowed. This portable rock splitter can be carried to any job site. The machine uses hydraulic pressure to push wedges into a drilled hole and split the material from inside.
YG Machinery makes reliable hydraulic rock splitters for construction, mining, and demolition work.

Main Structure of Rock Splitter Machine
This rock splitter machine has a few main parts:
Splitting Wedges – These are the parts that touch the rock. They are made of strong steel. The wedge set has one middle wedge and two side wedges.
Hydraulic Cylinder – This gives power to push the wedges. It uses oil pressure to move the wedges forward and backward.
Control System – This lets the operator control the rock splitter machine. You can change the splitting force and speed.
Hydraulic Power Unit – This sends high-pressure oil to the cylinder. It is small and easy to move around the job site. This portable rock splitter can be carried by one worker.
Working Principle
The working principle of this hydraulic rock splitter is simple. High-pressure oil pushes the middle wedge forward. The middle wedge goes between two side wedges and pushes them outward. This creates a strong splitting force that breaks the rock from inside.
Here are the steps:
Step 1: Drill a hole in the rock or concrete. Use 42mm or 46mm drill bit.
Step 2: Put the wedge set into the hole.
Step 3: Start the power unit. High-pressure oil pushes the middle wedge.
Step 4: The wedges expand inside the hole. The rock or concrete splits in 10 to 15 seconds.
Step 5: Move to the next hole and repeat.
This method makes no vibration. It is safe to use near buildings and roads. This is why many people choose non explosive demolition for city work.

Applications of Rock Splitting Equipment
This rock splitting equipment works well in many jobs.
Construction – This concrete splitter breaks concrete walls, floors, and columns when fixing or tearing down old buildings.
Mining – This rock splitter machine breaks big rocks into small pieces so they are easy to move and process.
Quarry – This hydraulic rock splitter gets big stone blocks from the mountain. Split along natural lines to get good quality stone.
Demolition – Tear down old buildings, bridges, and piers.
Tunnel – Break rock inside tunnels and subways. Good for small spaces where big machines cannot go.
Road and bridge – Remove old concrete when fixing roads and bridges.
For concrete placement after demolition, a small concrete pump moves material efficiently.

Why Choose YG Machinery
YG has been making hydraulic rock splitters for many years. The wedges are made of forged and heat-treated steel, so they do not break easily under high pressure. We test each rock splitter machine before shipping to make sure the hydraulic system has no leaks and the splitting force is correct. If you need spare wedges or hoses for your concrete splitter, we keep them in stock and can ship fast. Our factory makes these portable rock splitters directly, so you do not pay extra for a middleman.
For larger jobs, YG also offers excavator-mounted rock splitters. These attach to excavators and provide more splitting force for big rocks and heavy demolition work.
