Rammer rockbreakers increase productivity and lower lifetime costs

With integrated smart technology and user-focused features, Rammer Excellence Line of rockbreakers have helped users reduce breaking times and avoid unnecessary downtime.

Constant and high breaking power

Rammer Excellence Line of rockbreakers come with high pressure membrane accumulators to ensure constant and high breaking power is maintained at all times.

This means that they maintain their impact energy as they do not leak gas compared to piston accumulators, in which the gas behind the piston slowly leaks through the seals.

Instead, Rammer tools store nitrogen gas inside the rockbreaker which can last for extended periods of time, similar to the air in car tyres which only needs testing with regular servicing.

Avoiding gas leakage means avoiding a loss of impact energy and excessive downtime, plus the additional cost due to regular re-gassing.

This makes Rammer Rockbreakers a reliable and productive partner for a carrier, particularly in remote locations.

Reduced breaking times

Rammer’s patented Fixed Blow Energy operating principle ensures maximum impact energy regardless of the operating oil flow.

This means that every impact, from first to last, is at maximum power, regardless of oil flow or frequency, reducing breaking time and maximising productivity.

Idle Blow Protection

One of the main issues that can cause rockbreakers to prematurely break down is blank firing.

The piston strikes the tool and the tool strikes the rock, but if the piston doesn’t strike the tool, all the energy that’s normally transferred goes back inside the rockbreaker and causes internal components to fail over time.

Rammer has developed anti-blank firing which stops the unit working unless the piston is striking the tool.

The Idle Blow Protection (IBP) is easily adjustable on-site and ensures the rockbreaker can’t be operated until pressure is placed on the tool.

It also protects the tool from failures and tie rod stress, reduces oil overheating and protects against premature failures, which extends the life of the tool over time.

Remote monitoring

Rammer is the first on the market to add remote monitoring system for hydraulic rockbreakers.

The remote monitoring system, RD3 with the MyFleet platform enables users to monitor operating hours in real-time, know exactly where their equipment is and how it is being operated and schedule maintenance during times of least impact on production.

By using advanced electronics to sense the impacts and stresses on the rockbreaker, RD3 provides information on how the rockbreaker is being operated.

One of the major causes of premature failure in rockbreakers is long cycles where the operator continues to hit the button and the piston keeps striking for an extended period of time.

With RD3, users can remotely monitor rockbreaker usage and provide operator education when needed to avoid maintenance costs due to premature failure.

Correct operation minimises the chance that rockbreaker fails and causes costly unscheduled downtime.

The cloud-based monitoring system is available in all new Rammer Excellence models as standard.

Vidat tie rods

The patented Vibration Dampening Tie rods are at the cutting edge of tie rod technology, outlasting and outperforming standard tie rods and can improve bolt life up to three years.

Vibration during operation is a key cause of bolt breakage and by reducing the vibration through the bolts they last longer before they fail.


Sometimes rockbreakers can be damaged by too much oil flow. Rammer have developed the RamValve to stop the unit from working if the oil flow is too high.

Easy maintenance and service features

Simple lower tool bushing replacement

Users can rotate or replace the lower tool bushing in the field by removing the two easy-to-use pins. The replaceable lower tool bushing decreases maintenance costs all while reducing the cost of ownership and operating costs.

Improved greasing channels for tool bushings

Rammer has added separate greasing channels from the valve body into the lower and upper tool bushing.

This enables optimum greasing for both bushings which increases the lifetime of the tool and tool bushings, and of course saves money in maintenance.

User support

Rammer rockbreakers are manufactured in Finland by Sandvik Mining and Rock Technology and in Australia, user are supported by the authorised Rammer dealers.

Focusing on customer service and having genuine spare parts and tools available, Rammer dealers ensure that users continue to enjoy the industry leading performance and reliability they have grown to expect from Rammer products.
