New Cat E-Series hammers
Three new hammers designed to deliver enhanced durability and easy operation and maintenance
CATERPILLAR have added three new models to their E-Series hammer line – the H140Es, H160Es and H180Es – for use on medium and large excavators.
Designed for extended durability and reliability, and offering features such as automatic shut-off, silencing and vibration buffering, Cat E-Series hammers are designed to be field-serviceable with common hand tools to keep them operating at peak performance.
Wholly designed, engineered and manufactured by Caterpillar, the new hammers provide an optimum match with Cat excavators ranging from the 324E to the 374D L. Mounting brackets are available for Cat quick couplers.
The energy classes of the H140Es, H160Es and H180Es are 6,000ft-lb (8,135J), 8,500ft-lb (11,525J) and 12,000ft-lb (16,270J) respectively.
E-Series hammers feature a new symmetrical housing design, which allows for 180-degree rotation of the housing to compensate for wear, effectively extending the life of the housing. The lower portion of the housing incorporates protective rock edges to allow quick positioning of boulders. An optional wear package is available to further enhance hammer durability in severe applications.
Other E-Series features include automatic shut-off, which instantly stops the hammer when the tool breaks through material, thereby increasing hammer reliability and durability by eliminating the high internal stresses created by blank firing.
Another feature in each E Series Hammer is an external pressure control valve, which reduces service time when an adjustment is necessary, while sound suppression comes as standard for environmental protection and enhanced operator comfort.
Caterpillar hammer settings are pre-programmed in Cat excavator tool control systems for easy set up. The oil flow and pressure are fully adjustable in the tool control program, and actual hammer working hours can be recorded for routine maintenance purposes.
