Rock splits from the inside out.
Rocks are strong in compression and weak in tension. We use that weakness.
PISTON SPLITTER ROD / DL SERIES
Split from the Inside
The piston extends inside the borehole, expanding outward like an invisible wedge. Tensile stress does the rest, along the plane you choose.
3,500-Tonne Class Force
From about 1,500 t on the DL-90 to 3,500 t on the DL-180. Granite, basalt, reinforced concrete, and hard limestone split on demand.
Fast, Parallel Splitting
Each split takes 15-30 seconds, and one power unit runs up to six rods in parallel for output that multiplies.
Static, Safe, Permit-Free
No explosives, no vibration, no flyrock, no dust. Works in urban zones, sensitive sites, and gassy mines without blasting permits.
Field Proof

CASE FOOTAGE · PLUNGER SPLITTER
Three moves. Thirty seconds each.
Drill, insert, split, and move to the next hole.
Insert the Splitter
Place the piston rod into the hole and connect it to the power unit with the high-pressure and low-pressure hoses. One unit drives up to six rods.
Hydraulic Splitting
Rated pressure of 100-120 MPa drives the piston outward, generating up to 3,500 t of lateral force. The rock cracks in 15-30 seconds. Release, pull, repeat.
Four power units. One matched to your site.
Diesel for the field, electric for the grid. Two sizes of each.

Frequently asked questions.
What buyers ask before switching to piston splitting.
How fast is it compared with a breaker hammer?
Each split takes about 15-30 seconds, and one power unit runs up to six rods in parallel. For hard rock, the piston splitter consistently outproduces a breaker hammer.
Which power unit do I need?
Diesel DL-8P or DL-15P for field sites without grid power; electric DL-4KW or DL-7.5KW where power is available. Rated pressure runs 40-100 MPa depending on the unit, with peaks up to 120 MPa.
What borehole does it need?
Borehole diameter matches the rod: 90-180 mm, with a minimum depth of 1.0 m (compact models) or 1.5 m (DL-180). Hole spacing is 500-2,000 mm depending on the rod, per your rock plan.
Is it safe near buildings and in gassy mines?
Yes. Splitting is static and non-explosive: no vibration, no flyrock, no dust, no gas. It runs in urban zones, sensitive sites, and gassy mines without blasting permits.
