A very quiet and efficient method of controlled demolition used to remove large concrete structures such as foundations, pillars, bearers and concrete walls. Holes are drilled in the concrete structure and the bursting head, which contains a number of pistons, is inserted. Hydraulic pressure is provided by a motor, powered by electricity, diesel or petrol.
The build-up of lateral forces against the inside of the holes induces cracks in the concrete. The cracking follows the plane of weakness created by the holes that were drilled previously. The process is repeated until the whole structure is fractured into smaller sections and ready for removal.
Hand held crushing again is extremely effective operation and a practical method of reducing concrete walls to rubble. These tools provide a low noise operation for areas that are most sensitive and where other plant or equipment cannot be used.
A retractable counter balance is used to allow operators easy manoeuvring of the jaws.
