A hydraulic breaker pack consists of a petrol-powered hydraulic power pack connected by hose to a hand-held breaker gun. The power pack converts petrol engine output into hydraulic pressure, which drives the breaker piston at high frequency into the material being broken. The operator positions the breaker point, chisel, or spade on the surface and guides the tool as it works — the hydraulic system does the forcing.
Builders, demolition contractors, groundworkers, utilities companies, road repair crews, drainage installers, and property renovation teams all regularly hire hydraulic breakers. Common applications include breaking up concrete slabs before excavation, removing sections of asphalt or tarmac for reinstatement, cutting through block and brick walls during structural alterations, breaking frozen ground in winter site conditions, creating openings for drainage channels or utility routes, and general demolition of hard-standing areas and substructures.
The Belle Bulldog hydraulic power pack delivers 20 litres per minute at 140 bar of hydraulic pressure to the breaker gun. Its integrated Power-On-Demand system cuts fuel consumption by up to 50% compared to constant-run power packs by reducing engine speed when full hydraulic flow is not required, then bringing it back instantly when the trigger is pulled. This is what makes the hydraulic system considerably more fuel-efficient than a diesel road compressor running a pneumatic breaker at equivalent output.
