№637000 Hydraulic hammer to order, inexpensive

Got this Hanyun breaker bout 6 months back - total beast compared to our old stuff. Cranks out 3800 joules per hit which is why we grabbed it. Handles ridiculous jobs our other hammers couldn't touch. Been using it mostly for the tough commercial demos - ya know, those old foundations with rebar everywhere. 300 strikes a minute means you're not sitting around waiting. Had it on that hotel job down by the river - tore thru their basement walls like they were nothing. The special machinery runs pretty smooth for being such a heavy hitter. Only had to swap seals once since we got it. Keep the oils changed regular and it just keeps hammering.
