Rammer hydraulic breakers are recognized worldwide as some of the most reliable and innovative hydraulic hammers in the construction, demolition, quarrying, and mining industries. With a history spanning more than five decades, Rammer has played a significant role in the evolution of hydraulic breaker technology and continues to be a leading brand under the Sandvik umbrella.
Whether you are operating a Rammer hydraulic hammer, searching for replacement parts, or considering a rebuild of an older breaker, understanding the history and engineering behind these machines can help maximize performance and reduce operating costs.
Rammer was founded in Finland during the 1970s and quickly became one of the pioneers of hydraulic breaker technology. The company introduced innovative hammer designs that improved breaking efficiency while reducing downtime and maintenance requirements.
Over the years, Rammer established a strong reputation across Europe, North America, Australia, and Asia for producing durable hydraulic breakers capable of handling demanding applications such as:
Rock excavation
Quarry production
Mining operations
Concrete demolition
Road construction
Trenching projects
Today, Rammer operates as part of Sandvik Mining and Rock Solutions, one of the world's largest manufacturers of mining and construction equipment.

Many contractors and equipment owners are familiar with the names Allied, Rammer, and Sandvik. For decades, Rammer and Allied worked closely together, with certain breaker models marketed under the Allied-Rammer name.
As Sandvik expanded its global rock processing and mining equipment portfolio, Rammer became fully integrated into the Sandvik family. This relationship explains why older machines may carry Allied-Rammer branding while newer units are identified simply as Rammer or Sandvik Rammer breakers.
Because of this long history, many replacement parts and demolition tools remain interchangeable across certain Allied and Rammer models.
One of the unique characteristics of early Rammer hydraulic breakers was their fully hydraulic operating principle.
Unlike gas-assisted hydraulic breakers that rely heavily on nitrogen pressure to generate impact energy, Rammer's fully hydraulic system uses hydraulic oil pressure to control piston movement throughout the striking cycle.
A Rammer hydraulic hammer typically consists of:
Piston assembly
Control valve
Tool steel (chisel, moil point, or blunt)
Upper and lower bushings
Tie rods
Hydraulic seals
Nitrogen accumulator
Housing or silenced box
The hydraulic system lifts and accelerates the piston before impact, producing powerful and consistent blows against the working tool.
Fully hydraulic breaker technology offers several advantages:
Because hydraulic power controls the entire striking cycle, impact energy remains more stable throughout operation.
Although accumulators still contain nitrogen, overall breaker performance depends less on nitrogen pressure fluctuations than traditional gas-assisted designs.
Mining and quarry contractors often prefer fully hydraulic systems because they deliver reliable performance under continuous heavy loads.

A common misconception is that fully hydraulic breakers do not use nitrogen. In reality, virtually all fully hydraulic breakers utilize a nitrogen-charged accumulator.
The accumulator serves several critical functions:
Absorbing hydraulic pressure spikes
Reducing shock loads
Protecting hydraulic components
Improving energy recovery
Extending pump life
Most accumulators contain a rubber diaphragm that separates nitrogen gas from hydraulic oil.
Because diaphragms wear over time, regular inspection and replacement are essential for maintaining peak breaker performance.
One of the most recognizable features of Rammer breakers is their enclosed silenced housing.
Earlier hydraulic breakers commonly used side plate construction, which offered:
Simple maintenance
Lower manufacturing costs
Good heat dissipation
However, side plate breakers typically produced higher noise levels and transmitted more vibration to the carrier machine.
Rammer became well known for promoting fully enclosed silenced breaker housings.
Benefits include:
Lower operating noise
Improved operator comfort
Better protection of internal components
Reduced vibration transfer
Enhanced appearance and durability
Today, silenced box designs are widely adopted throughout the hydraulic breaker industry.
Throughout its history, Rammer has introduced several successful breaker generations.
The E Series represented some of Rammer's earliest hydraulic breaker designs and established the company's reputation for reliability.
The S Series improved hydraulic efficiency and durability while maintaining the robust design principles of earlier models.
Designed for larger carriers and more demanding applications, the G Series delivered increased impact energy and structural strength.
The M Series introduced improvements in piston design, operating efficiency, and serviceability.
The HR Series became a popular choice for medium and large excavators working in quarry and demolition environments.
The BR Series remains one of the most widely recognized Rammer product lines worldwide.
Its reputation is built on:
High reliability
Easy operation
Excellent parts availability
Long service life
Many BR Series breakers remain in operation decades after their original manufacture.

As technology has advanced, Rammer has continued to develop intelligent breaker systems.
Ramdata allows operators and fleet managers to monitor:
Working hours
Impact counts
Maintenance schedules
Utilization rates
Equipment performance
This technology helps reduce downtime and improve fleet productivity.
Modern Rammer breakers can automatically optimize:
Blow frequency
Impact energy
Hydraulic efficiency
The result is improved productivity and lower operating costs.
To complement the premium Rammer product line, Sandvik introduced the Bretec hydraulic breaker brand.
Bretec breakers are designed for:
General construction work
Cost-conscious contractors
Medium-duty applications
Together, Rammer and Bretec allow Sandvik to serve both premium and value-focused market segments.
Routine maintenance is essential for maximizing breaker life.
Operators should check:
Tool wear
Lubrication levels
Retaining pins
Hydraulic hoses
Visible leaks
Maintenance personnel should inspect:
Accumulator pressure
Tie rod torque
Bushing wear
Mounting hardware
Major rebuilds may include:
Seal kit replacement
Piston inspection
Bushing replacement
Accumulator diaphragm replacement
Tool retainer service
Proper rebuild procedures can significantly extend the life of a Rammer hydraulic hammer.
As many older Rammer and Allied-Rammer models remain in service, demand for replacement parts continues to grow.
Common replacement components include:
Chisels
Moil points
Blunt tools
Seal kits
Tie rods
Tool retainers
Upper bushings
Lower bushings
Accumulator diaphragms
Using high-quality OEM or aftermarket parts can help maintain performance while reducing ownership costs.
For more than 50 years, Rammer hydraulic breakers have been setting industry standards for reliability, performance, and innovation. From the early E Series to today's intelligent Rammer breakers equipped with advanced monitoring technology, the brand continues to play a leading role in demolition, mining, and construction applications worldwide.
