The new Rammer Performance Line hammers are your everyday solution for a wide range of breaking demands. Designed with proven Rammer features and standards, these Rammer Performance Line hammers offer more than just excellent power-to-weight ratio, they bring the quality reassurance that only a true Rammer hammer can.
The Ramdata II monitors vital functions including working hours, operating method and shift duration, using this information to help predict failures before they occur and schedule service and maintenance.
- Proven Technology
The Flange mounting mounting design allows for the use of existing mounting plates, as well as carrier and application specific customization.
Excellent power-to-weight ratio
RAMMER sets the standard in the industry with these outstanding values in the power-to-weight ratio.
The impact force has been increased and at the same time the operating weight has been optimized.
Idle Blow Protector
The Idle Blow Protection (IBP) ensures the hammer cannot be operated until pressure is placed on tool. This eliminates tie rod stress, reduces oil overheating and protects against premature failures.
Mounted greasing device, with adjustable flow and cartridge feed.
- Full Manufacture Warranty
Piston type accumulator
The nitrogen piston accumulator is a safe and durable design, thanks to the use of the latest sealing technologies, .
Fail-safe operation, high impact energy and simple and fast service help to improve your operating results.
- Vibration and sound suppressed
Heavy Duty Housing
Heavy duty housings feature a robust structure, are made of wear-resistant steel, with minimum number of holes.
Resulting in a longer housing lifetime even in the harshest of applications, reducing the cost of ownership through less maintenance.
- Excavator Friendly
- Large Tool Diameter/Length
Hydraulic excavators have largely replaced cranes with wrecking balls, enabling demolition to be carried out in a much more controlled and efficient manner.
Hammer fitted to an excavator working directly in a bench to breaks away rock which can then be removed by truck. This is most commonly used where blasting is not allowed.
When blasted rock is too big for the feeder or crusher, secondary breaking is needed to get the boulders down to size. The type of rock dictates the effectiveness of the process, with brittle rock giving the best performance.
