Hydraulic Breakers and Hammers
Handheld Hydraulic Breakers
Operator-held breakers run from a hydraulic power pack or a carrier's auxiliary circuit, for utility work, slab breaking and confined demolition. Vibration and weight decide how long they can be used.
Features
- Hydraulic drive gives more energy per kilogram of tool than a comparable pneumatic breaker and needs no compressor or airline.
- Vibration-damped handles are what determine how many hours a day the tool can legally and comfortably be used.
- Power pack flow and pressure have to match the tool; a mismatched pack shows up as low blow energy or an overheating tool.
- Underwater versions with exhaust routing exist for pier and cofferdam work.
- Tool steels, retainers and the bushing are the consumables, and the bushing wear determines when the tool starts to wander.
Specifications
| Figure | Typical range | Unit | Why it matters |
|---|---|---|---|
| Tool operating weight | 15 - 35 | kg | Sets what one operator can work with through a shift. |
| Required oil flow | 20 - 40 | l/min | Has to match the power pack or carrier circuit. |
| Impact rate | 1 000 - 2 500 | bpm | Governs output on slabs and thin concrete. |
