Pneumatic paving breaker

A handheld air breaker for concrete, asphalt and rock, in light, medium and heavy weight classes. The tool most site compressors exist to supply.

Features

Weight class decides the work: roughly 10 kg for slabs and asphalt, 20 kg for reinforced concrete, 30 kg and above for mass concrete and rock.
Impact energy per blow matters more than blow rate on hard material, and the two trade off against each other in the same air supply.
Anti-vibration handles and isolated grips cut declared vibration substantially, which directly extends permitted daily use.
The lubricator has to be set and checked — a dry breaker destroys its own piston and cylinder within hours.
Steels are consumables: moil points for breaking, chisels for cutting, asphalt blades for surfacing, all in the tool's shank size.

Figure	Typical range	Unit	Why it matters
Tool weight class	10 / 20 / 30	kg	Matches the tool to the material.
Air consumption	900 - 1 900	l/min	The compressor sizing input.
Impact rate	1 100 - 1 600	blows/min	With energy per blow, sets progress.
Shank size	25 × 108 / 32 × 152	mm	Fixes which steels fit.
Declared vibration	8 - 19	m/s²	Caps operator exposure time.
