Hydraulic bursting and crunching

Hydraulic bursting and crunching rigs use a combination of steel rams to apply extremely high but localised compressive or tensile stresses to break up concrete.

Bursting equipment is introduced into pre-cored holes, typically 150mm in diameter, and expanded hydraulically using a wedge like action to crack and burst the surrounding concrete into manageable sized sections.

Concrete crunching uses the opposite technique, whereby  hydraulic rams apply compressive forces to crush concrete sections.

The techniques are free of vibration and silent, and offer a cost effective way to remove concrete slabs and walls in noise, dust and vibration sensitive areas.

The hydraulic power pack can be powered by petrol, diesel or electric motors, allowing its use in a wide variety of environments including confined spaces.

Concrete crunching heads can be mounted on conventional or remote controlled tracked carriers with hydraulic booms, increasing capacity and productivity, whilst significantly reducing risk to operators.
