Heavy Hydraulic Breaker
High-energy breaker for excavators above roughly 25 t, used in quarry secondary breaking, hard rock excavation and heavy structural demolition.
Features
- High impact energy at a lower blow rate, which is what breaks massive hard rock rather than bruising it.
- Heavy silenced housing with replaceable wear plates on all bearing faces.
- Automatic greasing as standard, since manual lubrication cannot keep up at this duty.
- Requires a dedicated high-flow auxiliary circuit with adequate return capacity and cooling.
- Tool diameters above 150 mm, where tool cost per hour becomes a real line in the job budget.
Specifications
| Figure | Typical range | Unit | Why it matters |
|---|---|---|---|
| Carrier operating weight range | 25 - 70 | t | Only a heavy carrier can hold the tool down |
| Breaker service weight | 1 800 - 5 500 | kg | Substantial reduction in lift at reach |
| Impact energy class | 3 500 - 12 000 | J | Hard massive rock needs energy, not frequency |
| Required oil flow | 180 - 350 | l/min | Needs a dedicated high-flow circuit |
| Oil cooling requirement | cooler capacity per duty cycle | Continuous breaking heats the carrier's oil | |
| Tool diameter | 150 - 210 | mm | Tool consumption dominates running cost |
