The Complete History of Rammer Hydraulic Breakers

Rammer hydraulic breakers have a long history in the construction, demolition, quarrying, and mining industries. Over several decades, the Rammer brand has developed a broad range of hydraulic breakers for different carrier classes and working conditions, with a particular focus on durability, serviceability, and heavy-duty applications.

For equipment owners, contractors, rental companies, and hydraulic breaker distributors, understanding the development of Rammer breakers can provide useful context when evaluating equipment, sourcing replacement parts, or considering breaker replacement and rebuild options.

The Origins of Rammer Hydraulic Breakers

Rammer was established in Finland in the 1970s and became one of the established manufacturers in the development of hydraulic breaker technology.

As hydraulic excavators became increasingly common in construction and quarrying, hydraulic breakers provided a practical alternative to traditional mechanical and pneumatic breaking methods. Rammer developed breaker designs for applications ranging from general construction and roadwork to quarrying and heavy-duty rock excavation.

Over the following decades, Rammer expanded its international market presence across Europe, North America, Australia, and Asia. Its breakers have been used in applications such as:

  • Rock excavation

  • Quarrying

  • Mining

  • Concrete demolition

  • Road construction

  • Trenching

  • Infrastructure projects

Rammer is now part of Sandvik Mining and Rock Solutions, which provides equipment and solutions for mining and rock excavation industries.

The Relationship Between Rammer, Allied, and Sandvik

The relationship between Rammer, Allied, and Sandvik can be relevant when identifying older hydraulic breakers and sourcing replacement components.

Historically, some hydraulic breakers were marketed under the Allied-Rammer name. As the business developed, Rammer became part of Sandvik's broader mining and rock solutions organization.

As a result, equipment owners may encounter different branding depending on the production period and market. Older breakers may carry Allied-Rammer identification, while later products are generally associated with the Rammer brand within Sandvik's portfolio.

When sourcing replacement parts for older equipment, the breaker model, serial number, production year, and component specifications should be verified before placing an order. Compatibility should not be determined solely by the brand name.

How Rammer Hydraulic Breakers Work

Hydraulic breakers convert hydraulic energy from the carrier machine into mechanical impact energy. A hydraulic circuit controls piston movement, while the piston transfers impact energy to the working tool.

Depending on the breaker design and generation, hydraulic and accumulator systems work together to control the operating cycle and manage pressure fluctuations.

A typical hydraulic breaker assembly includes:

  • Piston

  • Control valve

  • Working tool

  • Upper and lower bushings

  • Tie rods or fastening components

  • Hydraulic seals

  • Accumulator

  • Housing or protective casing

The hydraulic system controls piston movement and delivers the impact cycle required to break concrete, rock, asphalt, and other materials.

The Role of the Nitrogen Accumulator

Nitrogen accumulators are an important component in many hydraulic breaker designs.

The accumulator stores energy and helps manage pressure fluctuations within the hydraulic circuit. It can also reduce hydraulic shock and support the breaker during the impact cycle.

Typical accumulator-related functions include:

  • Absorbing hydraulic pressure fluctuations

  • Supporting energy transfer during the impact cycle

  • Reducing hydraulic shock

  • Protecting hydraulic components

  • Improving operating stability

Because accumulator components are subject to wear, regular inspection is important. Diaphragm condition, gas pressure, and hydraulic connections should be checked according to the manufacturer's service requirements.

For maintenance teams, correct accumulator pressure is particularly important. Incorrect pressure can affect impact performance, hydraulic loading, and overall breaker operation.

Evolution of Silenced Hydraulic Breaker Housing

Breaker housing design has also developed significantly over the past several decades.

Traditional Side-Plate Breakers

Earlier hydraulic breakers commonly used side-plate structures. This design offered relatively straightforward access to internal components and was widely adopted across the industry.

However, open or partially enclosed structures could transmit more operating noise and vibration to the surrounding environment and carrier machine.

Box-Type and Silenced Housing

Enclosed box-type housings became increasingly common as contractors placed greater emphasis on noise control, operator comfort, and equipment protection.

A silenced housing can provide several practical benefits:

  • Reduced operating noise

  • Better protection of internal components

  • Reduced transmission of vibration

  • Improved suitability for urban construction

  • Additional protection against external contamination

Today, enclosed and silenced breaker designs are widely used for construction, demolition, and municipal applications.

Major Rammer Hydraulic Breaker Series

Throughout its history, Rammer has introduced several breaker product generations. Different series have been developed for specific carrier sizes and application requirements.

E Series

The E Series represents an earlier generation of Rammer hydraulic breakers and contributed to the development of the brand's product portfolio.

S Series

The S Series incorporated further developments in breaker construction, hydraulic performance, and serviceability.

G Series

The G Series was developed for larger carriers and demanding applications, with greater structural capacity and impact performance.

M Series

The M Series incorporated further developments in piston design, hydraulic operation, and maintenance access.

HR Series

The HR Series was developed for medium- and large-sized excavators and was used across applications including quarrying, demolition, and general heavy-duty construction.

BR Series

The BR Series is one of the most widely recognized Rammer breaker product families.

Its design philosophy has focused on:

  • Operational reliability

  • Serviceability

  • Parts support

  • Long working life

  • Application flexibility

A number of older BR Series breakers remain in service, creating continued demand for maintenance components and replacement working tools.

Modern Rammer Technologies

As hydraulic breaker technology has developed, manufacturers have increasingly incorporated monitoring and control functions into breaker systems.

Ramdata Monitoring System

Rammer's monitoring solutions can provide operating information such as working hours, impact counts, maintenance-related data, and equipment utilization.

For fleet managers and rental companies, this type of information can support preventive maintenance planning and equipment utilization management.

Impact and Operating Control

Modern hydraulic breakers can incorporate control technologies designed to manage operating parameters such as blow frequency and hydraulic flow.

The objective is to maintain suitable breaker performance across different materials and operating conditions while reducing unnecessary hydraulic loading.

For contractors, these technologies can be particularly useful when breakers are operated across multiple job sites or by different operators.

Bretec and the Broader Sandvik Breaker Portfolio

Bretec is another hydraulic breaker brand within Sandvik's product portfolio.

The brand has been positioned for applications where customers require practical hydraulic breaking solutions for general construction and medium-duty work.

The availability of different breaker brands and product ranges allows equipment suppliers and contractors to select products according to carrier size, application requirements, operating conditions, and budget.

Common Rammer Hydraulic Breaker Maintenance Procedures

Regular maintenance has a direct impact on breaker service life and operating costs.

Maintenance intervals should always follow the manufacturer's specifications and should be adjusted when breakers are exposed to particularly demanding working conditions.

Daily Inspections

Operators should check:

  • Working tool condition

  • Tool retainer components

  • Lubrication

  • Hydraulic hoses

  • Oil leakage

  • Abnormal noise or vibration

  • Mounting condition

Early identification of wear or leakage can help prevent more expensive component damage.

Periodic Inspections

Maintenance personnel should also inspect:

  • Accumulator condition and pressure

  • Tie rod or fastening condition

  • Bushing wear

  • Tool and retainer wear

  • Hydraulic seals

  • Mounting components

The inspection interval should be based on operating hours, application severity, and the manufacturer's maintenance recommendations.

Breaker Rebuilds

When internal components reach their service limits, a hydraulic breaker may require a partial or complete rebuild.

Depending on the condition of the breaker, a rebuild may involve:

  • Seal replacement

  • Piston inspection

  • Bushing replacement

  • Accumulator diaphragm replacement

  • Tool retainer replacement

  • Working tool replacement

  • Inspection of internal hydraulic components

A properly evaluated rebuild can extend the useful working life of an existing breaker and may be a practical alternative to purchasing a new unit.

Sourcing Replacement Parts for Rammer Breakers

Older Rammer and Allied-Rammer breakers remain in operation in many markets. As a result, replacement parts and working tools continue to be an important consideration for equipment owners and service companies.

Common replacement components include:

  • Chisels

  • Moil points

  • Blunt tools

  • Seal kits

  • Tie rods

  • Tool retainers

  • Upper bushings

  • Lower bushings

  • Accumulator diaphragms

When sourcing replacement components, buyers should provide the exact breaker model and serial number whenever possible. For non-OEM parts, dimensional specifications, material requirements, heat treatment, and application conditions should also be verified.

Choosing the correct replacement component is important not only for compatibility but also for maintaining breaker performance and protecting other internal components.

What Buyers Should Consider When Replacing an Older Hydraulic Breaker

For contractors, rental fleets, and distributors evaluating replacement options, brand history is only one part of the purchasing decision.

The following factors should also be considered:

Carrier compatibility: Confirm excavator operating weight, hydraulic flow, working pressure, return-line requirements, and mounting dimensions.

Application: Breaking concrete, asphalt, soft rock, hard rock, frozen ground, or quarry material can require different breaker configurations.

Duty cycle: A breaker used occasionally for general construction has different requirements from one operating continuously in a quarry or mining environment.

Service support: Parts availability, technical support, warranty coverage, and response time can have a significant impact on total ownership cost.

Maintenance requirements: Consider lubrication requirements, wear component life, service intervals, and the availability of rebuild components.

Supplier capability: For distributors and OEM customers, manufacturing capacity, engineering support, customization capability, and long-term parts supply should also be evaluated.

A hydraulic breaker should therefore be selected based on the complete operating requirement rather than brand recognition alone.
