Its Working principle is Like universal Hydraulic rock splitters consist of two wedges which are inserted in a pre-drilled hole and a hydraulic cylinder is pushing out a over-sized center wedge between the two side super sized counter wedges forcing them to separate.

This new design, it is more advance and high efficiency and productivity than traditional hand held hydraulic splitter.For vertical applications (shaftsinking, open pit excavation), the rock splitter is mounted on a chain or wire from a conventional excavator of 12-tons class or larger.

Wood box size : 2070mm*730mm*730mm, G.W. : 1090 KG.

Work process

1. Drill the hole of which diameter is bigger than 80mmØ and 1~3 meter deep by crawler drill, or ProDemo™ Excavator- Mounted Rock Drills available.

2. Switch on the Power switch on the control box.

3. Control the counter wedge is toward free face by wedge turning lever

4. Put the power jumbo cylinders into the holes and then push the rock toward the free face side.

5. Super wedge rock splitters consist of two over size wedges which are inserted in a pre-drilled hole and a hydraulic cylinder is pushing out a jumbo center wedge between the two side wedges forcing them to separate

6. Push down the center wedge by lever on the control box , Totally 12,000~ 24,00 ton power pushes the rock for 2-4 minute and then the rock will be split.

7. Breaking the rock, pull out the center wedge to the end.

8. Take out the wedge set from the hole for next hole break job.
