Concrete Crunching
Hydraulic
crunching for walls, concrete slabs or masonry
Crunchers are hydraulic jaws, which span a wall, concrete slab
or masonry, crushing and breaking as the jaws close.
Crunching is a fast controlled exercise, which is relatively dust,
vibration and noise free, they can be hand held or be an attachment
to a remote controlled demolition machine as shown in the picture.
