A new range of hydraulic hammers from Case have impact energy ratings from 350 to 1,200 foot-pounds. A narrow, rectangular shape, says Case, allows these tools to work in tight trenches and on congested demolition sites.Walt Moore, Senior Editor A new range of hydraulic hammers from Case have impact energy ratings from 350 to 1,200 foot-pounds.
