S1200 Hydraulic Rock Splitter
Heavy-Duty Splitting for High-Volume Rock Excavation
Small splitters are fine for a boulder or a slab, but they cannot keep up with a full excavation face. When you have to clear thousands of cubic metres of hard rock, and blasting is not allowed, you need a splitter with far more reach and force. The S1200 Hydraulic Rock Splitter is built for that scale. Drill a deep hole, lower the wedge set in, apply hydraulic pressure, and the rock opens up along the line you marked, quietly and without vibration.
It sits above the S950 in size and force and runs on an excavator, so the operator works from the cab. Here is what it offers and where it fits.
What Is the S1200, Really?
Picture a very large wedge that pushes outward from inside the hole instead of hitting from outside. The S1200 Rock Splitter uses a hydraulic cylinder to drive a centre wedge between two counter wedges, and it is designed to be carried by an excavator. Its long wedge set reaches deep holes, so it can open thick rock in one go and cover a lot of ground in a day.

How the Splitting Works
The cylinder pushes the centre wedge between the two counter wedges. The counter wedges press against the walls of the hole with enormous force, a crack starts, and it travels through the rock along your planned line. Put simply, this S1200 Heavy Duty Rock Splitter turns hydraulic pressure into a huge sideways force, with no noise and almost no vibration. One hole usually takes about a minute.
A typical job goes like this:
- Mark the splitting line and drill holes of 108 to 118 mm, roughly 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 thing that helps: 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 is made for open trenching, foundation excavation and tunnel work. As an S1200 Mining Rock Splitter, it suits open pits, shafts and micro-tunneling, where noise, vibration and flyrock need to be kept under control. Depending on the rock, it can clear roughly 250 to 300 m³ a day.
Why Controlled Splitting Makes Sense
Since the force acts from inside the material, the crack follows your line and the area around it stays intact. You also get large, clean pieces that are easier to load and haul away.
That lets work continue near roads, buildings and finished surfaces, which matters on sites where blasting is not an option.
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.
Made for Your Excavator
At around 850 kg, this splitter is meant to be carried by a machine, and that is what keeps it productive on big jobs. Fitted as an S1200 Excavator Mounted Rock Splitter, it moves from hole to hole in minutes while the operator stays safely in the cab.
Who Uses the S1200?
If your work needs high volume, deep holes and low noise, the S1200 is a strong choice.
