Hydraulic rock breakers
Download Darda catalog
Hydraulic rock breakers or hydraulic wedges can replace other demolition methods.
Much safer than blasting and expansive cement.
- Some models have a breaking strength exceeding 400 tons.
- They are lightweight, easy to use and transport.
- They break rock and concrete.
- Suitable for use in closed spaces or hard-to-reach places.
- It does not produce dust, noise or vibrations.
- It produces the break in seconds, it is precise and you can control the direction.
- It is easily controlled with one hand, except for the C20 model.
- They require a hydraulic group, except for the C20 model.
