December 7, 2016 – The largest hammer of the Cat E Series Hammer line is the H180Es. This premium hammer has a rugged design for extended durability and solid reliability, and offer features such as automatic shut-off, silencing and vibration buffering make them easy on the operator.

All E Series Hammers are designed to be field serviceable with common hand tools to keep them operating at peak performance.

Cat E Series hammers are wholly designed, engineered and manufactured by Caterpillar and are an optimum match to Cat carriers. The H180Es hammer matches up with Cat excavators ranging from 40 to 80t (349 – 374). Mounting brackets are available for Cat quick couplers. The energy class of the H180Es is 12,000 ft-lb (16,270 J).

E Series Hammers feature a symmetrical housing design, which allows rotating the housing 180 degrees to compensate for wear, effectively extending the life of the housing. The lower portion incorporates rock edges that add protection to the housing and enable quick positioning of boulders. An optional wear package is available to further enhance hammer durability in severe applications. The new housing is built for strength and lowers life cycle costs. E Series  hammers are fully supported by Cat dealers so that customers can work with a single organization for machine and work tool parts and service.


Caterpillar hammer settings are preprogrammed in Cat excavator tool control systems for easy set up. The oil flow and pressure are fully adjustable in the tool control program. Also, actual hammer working hours can be recorded for routine maintenance purposes.
