Along with hand crunching and bursting techniques, Denver Construction Services have also recognised the requirement for alternative machines that can accommodate larger controlled demolition projects. With this in mind, Denver Construction Services now operate in Brokk Robotic Demolition Machines which can operate in confined spaces, in weight restricted areas, in noise restricted areas, and are remote controlled for safer operation.

The operative controls the machine from a control box which is connected to the machine by cables and radio signal. The machine itself is powered by 3 phase electric, eleviating exhaust fumes and ensuring low noise output. The Brokk machine can be fitted with a percussive breaker, crunching jaws, and buckets, to suit a wide range of controlled demolition projects. The Brokk robotic machine also offers the complete solution to any potential HAVS problems.

Hand operated concrete crushers are now widely used by Denver Construction Services to quickly, quietly and with no vibration, break up walls, stairwells and in situ floor slabs up to 350mm thick. They are often employed in conjunction with diamond cutting techniques.

The unit (shown here) operates using high pressure hydraulic technology. A built in hydraulic ram opens and closes special alloy jaws to give crushing loads of 30 tonnes or more, which is normally sufficient to break the strongest of 300mm thick reinforced concrete walls. Hand operated crunchers used in confined working space areas are now in many cases the modern day alternative to noisey and dusty breakers. *With no hand arm vibration, they can also eliminate any potential HAVS problems.

Concrete bursting is a method of controlled demolition which once again is now widely used by Denver Construction Services. Bursting offers a noise free, quiet and efficient method of controlled demolition especially in confined space areas such as foundations, columns, beams and internal concrete walls. Holes are pre-drilled using non percussive diamond coring rigs (shown opposite) in the concrete structure to be demolished. On completion the burster head (which contains two pistons) is inserted into the required demolition grid hole.

Hydraulic pressure provided by 3 phase power, diesel or petrol power packs are then applied to the bursting head until such time as the build up of applied piston pressure inside the holes induces cracks in the concrete structure.The cracking itself follows the grid of weakness created by the previously drilled holes.

The bursting process continues and is repeated until such time that the entire structure has been fractured into smaller sections enabling debris removal to take place. Once again, with no hand arm vibration, bursting can eliminate any potential HAVS problems.
