As a package solution, the matching Caterpillar-designed hydraulic kits also are 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.
