In the heavy industries of mining, quarrying, and construction, the ability to process material efficiently is the cornerstone of profitability. However, the raw material rarely cooperates. Oversize rocks, stubborn concrete, and geological anomalies can bring even the most advanced operation to a grinding halt.
Enter the Hydraulic Rock Breaker.
More than just a demolition tool, modern rockbreaker systems are essential assets for asset protection and safety. Whether mounted on an excavator or installed as a stationary Rock Breaker Booms System over a crusher, these machines ensure that material flows continuously, protecting expensive infrastructure and removing personnel from harm's way.
This guide provides a comprehensive overview of rockbreaker technology, helping you understand the types, applications, and critical factors for selecting the right system.
At its core, a hydraulic rock breaker (or hydraulic hammer) is a percussion hammer powered by an auxiliary hydraulic system. It delivers a high-frequency, high-impact blow to fracture materials that are too hard or too large to be handled by crushing equipment or excavators alone.
Why are they important?
Safety: They eliminate the need for dangerous manual clearing of blockages or secondary blasting.
Productivity: They prevent downtime caused by "bridging" (blockages) in crushers and grizzlies.
Asset Protection: They prevent damage to crusher liners caused by forcing oversized material through the chamber.
Understanding the difference between these two configurations is vital for operational success.
These are attachments mounted on mobile carriers, such as excavators, skid steers, or backhoes.
Best For: Construction sites, road breaking, trenching, and versatile demolition work where the tool needs to move to the material.
Limitation: They require a dedicated operator and a fuel-burning vehicle to operate, which can be inefficient for fixed-location tasks.
This is the industry standard for mines and quarries. The system consists of a hydraulic hammer mounted on a multi-axis boom arm, which is bolted to a concrete or steel pedestal foundation.
Best For: Managing material flow at specific "choke points," such as primary jaw crushers, impact crushers, and grizzly screens.
The Advantage: A Stationary Rock Breaker Booms System is electrically powered (cheaper than diesel), provides full coverage of the crusher box, and can be operated remotely from a control room. It is the dedicated "guardian" of the crusher.
The versatility of rockbreakers allows them to serve multiple sectors.
Primary Crushing: Located at the tip head, a pedestal boom breaks oversized ore before it enters the jaw crusher to prevent jamming.
Grizzly Stations: Underground, booms are used to clear rocks that get stuck on the grizzly bars, ensuring ore passes flow freely.
Foundation Work: Excavating hard bedrock to create stable footings for skyscrapers and bridges.
Tunneling: Scaling loose rock from tunnel walls and breaking excavated material for removal.
Concrete Breaking: Pulverizing reinforced concrete structures.
Recycling Plants: Stationary booms are increasingly used in recycling yards to break large concrete slabs before they enter the impactor, similar to their use in mining.
Selecting the correct unit is not just about power; it’s about geometry and integration. Here are the three critical factors:
For stationary systems, the boom must be long enough to reach the furthest corner of the crusher box or grizzly, but also capable of tucking back into a "park position" to allow maintenance on the crusher.
Tip: Analyze your crusher layout carefully. Our Rock Breaker Booms Systems come in various reach lengths to match specific plant designs.
Bigger isn't always better. A hammer that is too powerful can damage the crusher or the boom itself. A hammer that is too weak will just bounce off the rock.
Factor: Match the impact energy (Joules) to the compressive strength of your rock and the size of the material you handle.
Is the unit working underground in a damp, corrosive environment? Or in a dusty, hot open-pit mine?
Factor: Look for heavy-duty slewing rings, robust hydraulic cylinders, and auto-greasing systems that reduce manual maintenance requirements.
The Hydraulic Rock Breaker is an investment in uptime. While mobile breakers offer versatility for construction, the Stationary Pedestal Boom is the undisputed king of efficiency for mining and aggregate processing.
By installing a dedicated system to handle oversize material, you are not just breaking rock; you are breaking the cycle of downtime, maintenance costs, and safety risks.

Q1: What is the main advantage of a stationary boom over an excavator?
A: A stationary Rock Breaker Booms System is powered by electricity, making it significantly cheaper to run than a diesel excavator. It also frees up your mobile fleet for other tasks and improves safety by removing the operator from the vibration and dust of the crusher deck.
Q2: How do I size a rockbreaker for my crusher?
A: The reach should cover the entire crusher opening plus the feeder area. The hammer size is determined by the maximum rock size you expect to encounter and the hardness of the material.
Q3: Can these systems be automated?
A: Yes. Modern pedestal booms can be equipped with remote control systems and advanced automation features that allow operators to control the breaker from a central control room, or even automate the parking and deployment sequences.
Q4: What maintenance does a rockbreaker require?
A: Regular greasing of the tool bushing is critical. Checking hydraulic nitrogen levels, inspecting hoses for leaks, and ensuring the boom's mounting bolts are torqued are also standard maintenance procedures.
