For Release in: Americas North & South: November 2013
Release Number: 365PR13
Ten new Cat® E-Series hammers - designed for use with mini excavators, skid-steer loaders and backhoe loaders - are available in both "silenced" and side-plate versions. Four sizes - H35, H45, H55 and H65 - are offered in two mounting configurations for installation on both Caterpillar and competitive carriers.
Silenced hammers, identified with "s" in the model designation, use a fully enclosed housing to suppress noise, a valuable feature in sensitive work environments and in small-machine applications in which the hammer is in close proximity to the operator. Non-silenced, side plate models are available for all four sizes.
Flat-top models allow versatility for installation on Caterpillar and equipment made by other manufacturers. Pin-on models are available for the H55E and H65E in applications that require a dedicated, hammer-equipped Cat machine.
Premium features
Several features assure convenient installation, comfortable operation and long hammer life. These hammers are designed and engineered to match auxiliary flows and pressures of the Cat machine. Plus, hydraulic ports are positioned for convenient installation. As soon as the hammer is "plugged" in, it is ready to perform.
Suspension system on the silenced models include buffers at the top and bottom to absorb reflective forces and isolate them from the machine. A suspension jack helps to dampen vibration and sound. The result is quiet, reliable operation and reduced operator fatigue.
To protect the hammer from internal stress, an automatic shut-off can be activated. This instantly stops the piston when the hammer breaks through material which in turn protects the hammer from blank-firing.
Easy maintenance
These new E-Series hammers include 47 percent fewer parts than did their D-Series predecessors. This allows for quicker and easier servicing. When it comes to daily maintenance, a single grease point is conveniently located and easily accessed. Tool changes are accomplished with common hand tools.
