To improve performance and simplify service, Caterpillar has introduced the H140D hydraulic hammer with a redesigned operating cycle. The new design has an impact energy rating of 3,155 foot-pounds (2 percent more than the C-series model) and an impact frequency of 350 to 600 blows per minute (25 to 30 percent higher). The H140D is ideally matched to Cat 325C and 330C excavators and can also be used with Cat 322C or similar sized excavators. An automatic shutoff feature stops the hammer when it has no material underneath it, which prevents blank firing and extends the hammer’s life.
