S1200-E Hydraulic Rock Splitter
Excavator-Driven Power for Large-Scale Rock Removal
On a big excavation, the slowest part is often the rock itself. Blasting is risky near roads and buildings, and breakers make a lot of noise and shake everything around them. A large hydraulic splitter avoids both problems. The S1200-E Hydraulic Rock Splitter is made for this kind of work. You drill a deep hole, lower the wedge set into it, apply pressure, and the rock parts along the line you marked.
It is designed to be run by an excavator, so the operator stays in the cab while the splitter does the heavy work. Here is what it offers and where it fits.

What Is the S1200-E, Really?
Think of a very large wedge that works from inside the hole and pushes the rock apart. The S1200-E Rock Splitter has a hydraulic cylinder that drives a centre wedge between two counter wedges, and its long wedge set reaches deep holes. That depth is what lets it open thick rock in a single pass and keep a steady pace across a whole site.

How the Splitting Works
Hydraulic pressure moves the centre wedge forward between the two counter wedges. The counter wedges push hard on the hole walls, a crack begins, and it spreads through the rock along your planned line. In simple terms, the S1200-E Rock Splitting Machine converts hydraulic pressure into a very large sideways force, quietly and with almost no vibration. Each hole takes about a minute.
A typical job goes like this:
- Mark the splitting line and drill holes of 108 to 118 mm, about 1800 to 2000 mm deep.
- Lower the wedge set into the hole.
- Connect the hydraulic supply from the excavator and start.
- Keep building pressure until the rock opens up.
One useful habit: drill your holes towards a free face. The split pieces get room to move, and the break comes away cleaner.
Where You Can Use It
The S1200-E is at home on open trenching, foundation excavation and tunnel work. As an S1200-E Heavy Duty Rock Splitter, it also handles open pits, shafts, micro-tunneling and mining faces, where hard rock has to come out without blasting. Concrete demolition on large structures is well within its range too.
Why Controlled Splitting Makes Sense
The force acts from inside the rock, so the crack follows your line and the ground around it stays intact. You also get large, clean pieces that are easy to load and haul away.
That means work can carry on next to roads, buildings and finished surfaces, which matters on sites where blasting is not allowed.
Prepare Before You Begin
A little preparation saves a lot of time on site:
Safety and Maintenance
Good habits keep the tool reliable, project after project.
Built to Run on Your Excavator
At around 850 kg, this splitter is meant to be carried by a machine. Used as an S1200-E Excavator Rock Splitter, it moves from hole to hole in minutes while the operator stays safely in the cab, which keeps the whole job moving.
Who Uses the S1200-E?
If your work needs deep holes, high force and low noise, the S1200-E is a strong choice.
