Introducing new CAT® Hammers H190s & H215s Easier And Safer With Advanced Technology

Hydraulic hammers are one of the most versatile work tools available and able to extend the usefulness of skid steer loaders, backhoe loaders and excavators of all sizes in applications from civil construction, road building, earthmoving, quarrying and mining.

New hydraulic hammers H190S and H125S are now added to the Cat® hammer line-up which offers high levels of features and technology that delivers greater productivity at the jobsite. “The introduction of these hammer models expands the portfolio and supports our strategy of offering customers options at differing value points,” Cat Work Tools consultant Mr Jason Zhang stated. He also added that these new hammers cover Cat 349-395 excavators with carrier weight ranging from 45 tonne to 120 tonne fulfilling the hammer need for the large excavators like 374 and 395.

“These hammers are simple to operate and require less time on service, which in turn boosts the productivity at the job site.

The hammer hits with consistent power and can be switched between blow frequency and power to best suit different applications and improve efficiency.”

The Power Adjust feature on H190S and H215S hammers allows the operators to manually adjust the power of the breaker for different materials and applications. The long stroke has less piston frequency which results in higher impact power and productivity and it is best for harder materials and strenuous applications, while the short stroke has higher piston frequency which results in less impact power and it is best for lighter applications.

“This allows the operators to determine the desired piston speed based on the materials and applications to increase the productivity and efficiency while lowering the fuel consumption,’’ Mr Zhang added.

The hammers also offer an overflow protection function. This function is performed by the Internal restrictor valve in the hammer, which detects the overflow of hydraulic oil from the excavator. It limits and adjusts the oil flow to the hammer. “This feature prevents the over speeding of the piston and avoids costly damages and rebuilds – reducing your operating costs,” he stated.

The Automatic Shut Off (ASO) feature on H190S and H215S hammers offers protection against blank firing by stopping the piston from cycling internally when there is no material under the tool.

Mr Zhang said, “Eliminating blank firing helps protect the hammer from premature damage by reducing internal stresses and heat and this helps to lower overall hammer ownership and operating costs. Additionally, ASO will protect rental fleet hammers where operator skill level and expertise can vary.” This feature can be easily set to on or off in the field.

The hammers are protected by the Auto stop feature. This feature warns the operator when the hammer is hammering too long in one spot. A warning message will pop up on the screen after 15 second of permanent hammer activation and after exceeding 30 second, the hammer will automatically stop. Mr Zhang explained that “this feature helps prevent premature damage to the hammer and machine, even with an inexperienced operator”.

A hammer mounted auto lube system is a standard offering in these hammers. “This auto lube system provides continual greasing while the hammer runs – saving your time and protecting your investment,” he said.

Mr Zhang described that the hammers are also configured with the Oil-fired design to ensure less waste is generated in internal heat providing more power to the tool which delivers efficient operating cycle and consistent production over time.

The maintenance is very easy in these new hammers, all the daily checks and routine service can be performed while the hammer is attached to the machine. “Easy and quick access to critical lubrication points and all other maintenance areas ensures the hammers are ready to operate at their peak and helps to reduce maintenance costs over the life of the tool,” Mr Zhang said. “Service of the lower bushing can be carried out in the field using simple hand tools and the bushing is rotatable to 90 degrees, which doubles the life reducing the overall service time and lowering the owning and operating costs,” he further added.

The hammers are designed to keep the gas pressure steady through the duration of the annual service interval eliminating the need for constant checking of the gas charge. “You can also verify the gas charge of the hammer without removing it from the carrier,” Mr Zhang explained.

A buffer system fitted inside the hammer housing to protect the carrier from potentially damaging reflective forces. The system also helps to reduce vibration to the machine, improves noise suppression and aids hammer durability.

Hammer Auto – Stop

Will give the operator an indicator in the cab when operating the hammer in one location at 15 seconds. Hammer will automatically stop after exceeding 30 seconds.

E – Fence
When operator hammer, dimension points for ceiling, floor, front can be programmed when needed.

Both hammer models will ship from the factory with PL 161 mounted on the hammer housing. Machine can receive the hammers ID and select appropriate settings (flows and pressure) automatically from the pre-loaded work tool list on the HEX by using information from the PL161 via Bluetooth communication.

Overall, the Cat hammer portfolio are configured to ensure that they prioritise safety and offer best choices that are suited for all customer needs while delivering efficient productivity and durability.
