Rammer hydraulic breakers have established a strong reputation in the global construction, demolition, quarrying, and mining industries. With more than five decades of development, the Rammer brand has contributed to the evolution of hydraulic breaker technology through continuous improvements in impact performance, durability, serviceability, and operator safety.
For contractors, equipment rental companies, dealers, and fleet managers, understanding the development of Rammer hydraulic breakers provides useful insight into breaker design, maintenance requirements, and long-term equipment ownership.
Whether you operate an existing Rammer hydraulic breaker, source replacement components, or evaluate alternative hydraulic hammer solutions, understanding the brand's engineering development can support more informed purchasing and maintenance decisions.
The Origins of Rammer Hydraulic Breakers
Rammer was established in Finland in the 1970s and became one of the early manufacturers to specialize in hydraulic breaker technology. Its product development focused on improving rock-breaking and demolition efficiency while maintaining equipment durability under demanding working conditions.
Over the following decades, Rammer hydraulic breakers gained recognition in major construction and mining markets, including Europe, North America, Australia, and Asia.
The breakers have been widely applied in:
Rock excavation
Quarrying
Mining
Concrete demolition
Road construction
Trenching
Infrastructure projects
The brand later became part of Sandvik Mining and Rock Solutions, integrating Rammer into a broader global portfolio of mining, construction, and rock-processing equipment.
For equipment owners, this development is important because the Rammer product line has benefited from Sandvik's global engineering, distribution, and aftermarket support capabilities.
The Relationship Between Rammer, Allied, and Sandvik
The history of Rammer hydraulic breakers is also closely associated with Allied and Sandvik.
For many years, certain hydraulic breakers were marketed under the Allied-Rammer name. As Sandvik expanded its presence in the mining and construction equipment sector, Rammer became part of the Sandvik organization.
As a result, equipment owners may encounter different branding on breakers from different generations, including Allied-Rammer, Rammer, and Sandvik Rammer.
This history is particularly relevant when sourcing replacement components for older breakers. Before purchasing parts, operators and dealers should confirm the breaker model, serial number, component dimensions, and applicable technical specifications rather than relying solely on brand names.
How Rammer Hydraulic Breakers Work
Rammer has developed hydraulic breakers based on fully hydraulic operating principles. In these systems, hydraulic pressure controls the piston movement and striking cycle to convert hydraulic energy into impact energy.
A typical hydraulic breaker includes several major components:
Piston assembly
Control valve
Working tool
Upper and lower bushings
Tie rods
Hydraulic seals
Nitrogen accumulator
Housing or silenced enclosure
During operation, hydraulic oil drives the piston through its operating cycle. The piston then transfers energy to the working tool, such as a moil point, chisel, or blunt tool, which delivers the impact to the material being processed.
The overall performance of a breaker depends on the interaction between hydraulic pressure, oil flow, piston design, accumulator performance, working-tool condition, and carrier compatibility.
For this reason, selecting a hydraulic breaker should involve more than comparing impact frequency or breaker weight. The carrier's hydraulic specifications and the intended application must also be considered.
Why Fully Hydraulic Breakers Became Important
Fully hydraulic breaker technology has become widely used in demanding construction, quarrying, and mining applications because it allows manufacturers to precisely control the hydraulic operating cycle.
Key benefits include:
Stable Impact Performance
A properly matched hydraulic system can provide consistent piston movement and impact performance throughout the working cycle.
Efficient Energy Transfer
The hydraulic circuit is designed to transfer energy from the excavator's hydraulic system to the breaker piston and working tool efficiently.
Suitability for Heavy-Duty Applications
With appropriate structural design and hydraulic matching, fully hydraulic breakers can be used in demanding applications such as quarrying, mining, demolition, and large-scale infrastructure work.
However, actual performance depends heavily on hydraulic settings, maintenance condition, carrier compatibility, and operating practices.
The Role of the Nitrogen Accumulator
One common misunderstanding is that a fully hydraulic breaker does not use nitrogen. In practice, many hydraulic breakers incorporate a nitrogen-charged accumulator as an important part of the energy-management system.
The accumulator can help:
Absorb hydraulic pressure fluctuations
Reduce pressure shocks within the circuit
Support the breaker operating cycle
Improve energy utilization
Reduce stress on hydraulic components
The accumulator normally contains a diaphragm or similar separation element that keeps nitrogen gas separate from hydraulic oil.
Because accumulator components can deteriorate with use, maintenance personnel should periodically inspect nitrogen pressure and accumulator condition according to the manufacturer's service requirements.
Incorrect nitrogen pressure can affect breaker performance and may increase stress on other components.
Evolution of Rammer's Silenced Housing Design
One of the recognizable characteristics of modern Rammer hydraulic breakers is the enclosed housing design.
Traditional Side-Plate Breakers
Earlier breaker designs commonly used side plates to hold and protect the main components. These structures offered several practical advantages, including relatively straightforward maintenance and good accessibility to internal components.
However, exposed or semi-enclosed designs could transmit more mechanical noise and vibration to the surrounding environment and carrier machine.
Box-Type and Silenced Housing
Enclosed breaker housings were developed to provide additional protection for internal components while also helping to control operating noise and vibration.
Typical benefits include:
Reduced external noise
Improved operator working conditions
Additional protection for internal components
Reduced exposure of the breaker to external impact
Improved overall equipment appearance
Today, enclosed and sound-suppressed designs are widely used across the hydraulic breaker industry, particularly for urban demolition, road construction, and other applications where noise control is important.

Over its long product history, Rammer has introduced multiple breaker series for different carrier sizes and applications.
E Series
The E Series represents an earlier generation of Rammer hydraulic breakers and helped establish the brand's position in the hydraulic breaker market.
S Series
The S Series incorporated further improvements in hydraulic performance, structural durability, and serviceability.
G Series
The G Series was developed for larger carriers and demanding applications where higher impact performance and structural strength were required.
M Series
The M Series introduced further developments in piston design, hydraulic efficiency, and maintenance accessibility.
HR Series
The HR Series was designed for medium and large excavators and found applications in quarrying, demolition, and general heavy-duty construction.
BR Series
The BR Series became one of the most recognizable Rammer product families. Its market reputation has been associated with durability, serviceability, and long operating life.
For owners of older BR Series breakers, maintaining the correct working-tool dimensions, bushing condition, hydraulic settings, and lubrication schedule remains important for achieving reliable performance.
Modern Rammer Technology and Monitoring
Hydraulic breaker technology has continued to develop beyond mechanical performance. Modern systems increasingly incorporate monitoring and data-management functions to help equipment owners improve fleet utilization and maintenance planning.
Ramdata Monitoring
Rammer's Ramdata technology provides information that can support equipment management, including operating hours, impact counts, maintenance information, utilization, and equipment performance.
For rental fleets and contractors operating multiple machines, this type of data can help maintenance teams schedule service more effectively and identify equipment utilization patterns.
Intelligent Impact Management
Modern hydraulic breakers can also incorporate control technologies designed to optimize impact frequency, energy output, and hydraulic performance according to operating conditions.
The objective is to improve productivity while reducing unnecessary energy consumption and component wear.
For fleet operators, these developments are increasingly relevant because total cost of ownership depends not only on purchase price but also on productivity, maintenance requirements, fuel consumption, component life, and downtime.
