Caterpillar has introduced two new hydraulic breakers as part of its Performance Series Hammers range.

The new Cat H190 S and the H215 S models are the largest in the attachment range, which comprises seven other models, and have been designed for use on large excavators for demolition, quarry, and general construction applications.

They are built for high production tasks and are said to deliver consistent breaking power and emit less waste from internal heat for more power delivered to the tool.

“With piston and tool matched in diameter and mass, these new hammers offer increased power transmission frequency,” said Cat.

“Operators can switch power mode from high frequency/low power to low frequency/high power, giving the ability to fine tune power to the material being broken.”

Now available in Europe, North America and South America, the H190 S and H215 S offer 370 to 530 and 300 to 520 hammer blows per minute respectively. 

The breakers include a buffering material that dampens vibration feedback to the carrier and they can be configured for joystick or pedal control to suit the operators preference. 

They are also equipped with an automatic shut-off that prevents blank firing and hammer damage. According to the manfacturer, the feature can be turned off to allow for horizontal and overhead operation on tunneling and mining applications.

Specifically designed for use with Cat’s next gen excavators, the H190 S hammer is sized for mounting on Cat machines with operating weights of between 43 and 80 t, which includes the Cat 349 through to the 374 excavator models.

Meanwhile the larger H215 S is designed for use with the 374 and 395 machines, weighted at between 65 and 120 t.

“Next gen excavators automatically recognise the H190 S and H215 S Hammers and prompt operators to select the correct tool programme,” said Cat.

“Protecting the cab and keeping the attachment in predefined operating areas at the jobsite, the new hammer dimensions are included in Cat E-Fence technology.”

Users can also configure the hammer’s pressure and flow rates on the in-cab touchscreen through Cat’s excavators Product Link technology via the Cat App.

Both models include an on-board autolube system as standard, providing continual greasing during hammer operation to improve attachment longevity, and are available with an optional wear package that protects the hammer housing when working in extreme environments.
