The Atlas Copco LH 390 is a 60 lb-class handheld hydraulic paving breaker for heavy concrete break-out, bridge-deck demolition, full-depth asphalt removal, footing and pile-cap work and frozen-soil utility trenching. Fed 8 GPM of hydraulic oil at 1,668-1,886 psi from a portable power pack or a skid-steer or excavator auxiliary circuit it delivers 1,150-1,600 BPM from a 73 lb, 30 in. tool with no compressor on site.

Where air is impractical, hydraulics carry the day: one quiet power source, two hoses, full breaker performance, with return-line pressure capped at 290 psi. Crowder Supply stocks matching power packs alongside the Atlas Copco hydraulic breaker line. Chucks in 1-1/8 x 6 in. and 1-1/4 x 6 in. hex run standard heavy steels and if you are comparing hydraulic against air and gas designs, start with the paving breaker guide.

Atlas Copco LH 390 FAQ

What do I need to power the LH 390?
A hydraulic supply of 8 GPM at 1,668-1,886 psi with return-line pressure no higher than 290 psi from a portable power pack or the auxiliary circuit of a skid steer or excavator. No compressor is required.

Is the LH 390 a mounted excavator breaker?
No it is a 73 lb handheld paving breaker. A skid steer or excavator only serves as its hydraulic power source through the auxiliary circuit; the tool itself is operated by hand.

Which handheld hydraulic breaker class do I need?
The 60 lb-class LH 390 handles heavy break-out such as bridge decks and pile caps on an 8 GPM circuit. For lighter slab and sidewalk work on 5 GPM, look at the 40 lb-class Chicago Pneumatic BRK 40 VR.
