CAT® B-PREFIX HAMMERS FEATURE LOW OWNING AND OPERATING COSTS, VERSATILITY, EASE OF USE MACHINE PRODUCT & SERVICE ANNOUNCEMENTS CAT® B-PREFIX HAMMERS FEATURE LOW OWNING AND OPERATING COSTS, VERSATILITY, EASE OF USE For Worldwide Release: June 2018 Release Number: 131PR18 Cat® B-Prefix hydraulic hammers, available in B4(s) and B6(s) silenced and B4 and B6 non-silenced versions, are designed for "plug-and-play" operation with a range of compact equipment—while delivering optimum life-cycle value. The new hammers are suited for skid steer loaders, multi-terrain loaders, compact track loaders, mini hydraulic excavators (3- to 8-ton operating weights), and backhoe loaders working in a range of construction and light-demolition applications, including site prep, landscaping, masonry, and concrete breaking.
