When construction jobs require rock or concrete demolition, the rock breaker machines are indispensable. Aptly named, as they are designed and built for the sole purpose of breaking rocks to manageable sizes which can then be moved safely and efficiently.

These powerful machines are a common sight on construction sites where substantial demolition work is required. In this blog post, we will explore all about the mighty rock breaker machines.

Understanding the Rock Breaker Machine

A rock breaker machine, also known as a hydraulic hammer, is a piece of construction machinery that is attached to excavators, backhoes, skid steers, and mini excavators. It consists of an arm which is the extension, and at the end of which is the hammer, which delivers repeated force to shatter rocks/ concrete into smaller and manageable pieces.

Components and Types of Rock Breakers

A typical rock breaker consists of two main parts: a hammer (used to crush the hard materials) and an arm to which the hammer is attached. The size and design of rock breakers can vary. Depending on the operational requirements, they can range from small, handheld devices to large, powerful machines mounted on construction vehicles.

Impact Rate:

Typically ranging from 500 to 1,500 blows per minute.

Tool Diameter:

Usually between 45 to 175 mm, tailored to the scale of work.

Carrier Weight:

Matching the excavator or backhoes weight, from 1 ton to over 50 tons, ensuring stability and efficiency.

Hydraulic Flow:

Required flow rates can vary from 20 to 150 liters per minute, aligning with the machinerys hydraulic capabilities.

The Operational Mechanics of how Rock Breakers Workx`

The operation of a rock breaker is relatively straightforward, and highly efficient. It employs a high-pressure hydraulic system, which supplies hydraulic fluid to the rock breaker’s cylinder. This fluid puts pressure on a piston, which, in turn, transfers the force to a tool shaft, usually a steel chisel. The repeated hammering action of the chisel into the rock or concrete breaks it apart.

Rock Breaker Machine Efficiency

Efficiency in rock breaking is achieved through the powerful, concentrated force that the rock breaker exerts on the material. Unlike traditional methods of rock breaking that require multiple workers and various construction tools, a rock breaker machine delivers swift and powerful blows, shattering rock and concrete efficiently and at a significantly lower cost. The efficiency parameters of a rock breaker include:

• Energy Output: Energy delivered per blow, directly affecting breakage capacity.
• Operational Weight: Balancing the machines heft with its output force to optimize energy transfer.

Applications of Rock Breakers in Construction

The versatility of rock breakers allows them to be used in various construction and demolition tasks. These include:

• Excavating foundations
• Trenching rocky ground
• Tunnelling through rock
• Demolishing concrete structures
• Secondary breaking in quarries

Maintenance of Rock Breaker Machines

Proper maintenance is crucial to ensure the longevity and effectiveness of a rock breaker. Routine inspections for wear and tear, regular greasing to maintain parts lubrication, and ensuring hydraulic systems are free from contaminants are all part of the upkeep for this robust construction equipment.

Conclusion

A rock breaker machine is an indispensable component of the construction industry’s machinery arsenal. It stands as a testament to the advancements in construction vehicles and equipment technology, providing a practical and cost-effective solution for rock and concrete removal. With proper maintenance and operation, rock breakers can greatly enhance productivity, ensuring that construction projects stay on track and within budget.

When you’re in the market to purchase a rock breaker, understanding its operation and care will help you make an informed decision, ensuring you have the right equipment for your construction needs.
