darda Hydraulic rock splitter

1. instruction

Hydraulic rock splitter can reduce costs, save time and make demolition work profitable using the hydraulic splitting method. Hydraulic splitting means controlled demolition. As the direction of breaks can be determined, concrete can be cut in sections as large as your equipment can handle. Hydraulic splitting eliminates both shocks and vibrations associated with large impact tools.

We have four types of PowerStation for the hydraulic rock splitter: pneumatic, electric, gasoline, diesel. Every type of PowerStation can hole up to ten cylinders.

2.working principle

Phase 1

First, a hole of a precise diameter and depth is drilled into the material. The wedge set (one wedge and two counter wedges) is inserted into the drill-hole.

Phase 2

The wedge is driven forward under hydraulic pressure, forcing the counter wedges apart with a force of up to about 700 tons. The materialsplits within seconds.

Phase 3

With enlarging counter wedges the split can be expanded to its maximum width. Reinforcing rods break or can be cut up with a suitable power tool
