Cat B-Prefix Hydraulic Hammers
Cat’s B-Prefix hydraulic hammers could be your next exceptional choice when it comes to a machine that is not only simple in design and maintenance, but also offers exceptional reliability and ease-of-use. This line of hammers was designed for operations 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. Designed for “plug-and-play” operation, these versatile hammers are available in B4(s) and B6(s) silenced and B4 and B6 non-silenced versions. As a package solution, the matching Caterpillar-designed hydraulic kits are also offered and the best fit for Cat machines, providing customers a breaker package with superior design and benefits.

Quality engineered

  • Design

    • Simple, reliable, industry-standard modular design with two moving parts in the piston and valve

    • Flat-top mounting enables compact working envelope and compatibility with a full complement of brackets to suit preference of coupler, linkage kinematics, or machine size

  • Field service

    • Bushings are field-replaceable, and lower bushing can be rotated 90 degrees for improved wear performance

    • Included toolbox contains charging kit, hammer paste, and spare parts

    • Housings are designed to facilitate common maintenance items. Grease fitting and gas pressure check point are easily accessed with hammer on machine

  • Gas operation

    • Gas-fired operation cycle delivers consistent, long-term high production

  • Major components

    • Cylinder, back-head, front-head, piston, and tool are manufactured with high - quality materials and processes

  • Housings

    • Heavy-duty housing construction protects against breakage and wear

  • Piston

    • Piston transfers long shock waves into material; piston diameters are matched for maximum energy transfer; piston design and surface finish provide superior oil retention and seal life

  • Oil-control valve

    • Inward-type oil-control valve has high structural integrity and low failure rate

  • Mounting brackets

    • Interchangeability between H-prefix and B-prefix models

Tool types for the new hammers include moil, cone, parallel and transverse chisel, and blunt, allowing the hammer to be adapted to an extensive range of applications.
