An excavator breaker, also known as a hydraulic breaker, hydraulic hammer, or rock breaker, is an attachment designed for excavators. It is a powerful demolition tool used to break through hard materials such as concrete, asphalt, rocks, and other solid surfaces.
The excavator breaker operates by utilizing hydraulic power from the excavator's hydraulic system. It consists of the following key components:
1. Breaker Body: The main housing or casing that encloses the internal components of the hydraulic breaker.
2. Piston: The reciprocating component that moves inside the breaker body, generating the striking force.
3. Chisel or Tool: The working end of the breaker that directly contacts the material being broken. Various types of chisels are available to suit different applications, such as moil points, blunt ends, or specialized shapes for specific tasks.
4. Front Head: The front part of the breaker that connects to the excavator's attachment mounting bracket.
5. Hydraulic System: The hydraulic breaker utilizes the hydraulic power provided by the excavator's hydraulic system. It typically requires hydraulic hoses to connect to the excavator's hydraulic lines.
The hydraulic breaker is operated by the excavator operator from the cabin. As the hydraulic system delivers oil under pressure to the breaker, the piston inside the breaker body rapidly moves back and forth, striking the chisel against the material. The repeated impact and force exerted by the chisel break the material into smaller pieces.
Excavator breakers are commonly used in construction, demolition, quarrying, mining, and other industries where efficient and precise breaking of hard materials is required. They offer advantages such as high breaking power, versatility, and the ability to work in confined spaces.
Different sizes and models of excavator breakers are available to accommodate various excavator sizes and applications. It's essential to select a breaker that matches the excavator's specifications and the intended task to ensure optimal performance and productivity.
Some common excavator breaker parts
The excavator breaker consists of several key parts that work together to enable its operation. The specific parts can vary slightly depending on the manufacturer and model of the hydraulic breaker, but here are some common excavator breaker parts:
1. Breaker Body: The main housing or casing that contains the internal components of the hydraulic breaker.
2. Piston: The reciprocating component that moves inside the breaker body, delivering the striking force to the chisel.
3. Chisel or Tool: The working end of the breaker that directly contacts and breaks the material. Chisels come in various shapes and sizes to suit different applications.
4. Front Head: The front part of the breaker that connects to the excavator's attachment mounting bracket.
5. Accumulator: A gas-filled chamber that helps absorb and dampen hydraulic pressure spikes during operation, reducing stress on the breaker and excavator.
6. Seals and O-rings: These components are used to maintain hydraulic fluid integrity and prevent leaks in the hydraulic system.
7. Valves and Valving System: The hydraulic valves control the flow of hydraulic fluid, regulating the operation and impact frequency of the breaker.
8. Retaining Pins and Bushings: These components secure the chisel or tool to the breaker body, allowing for easy replacement and maintenance.
9. Wear Parts: These include wear plates, wear bushings, and wear rings that protect the breaker body from abrasion and extend its lifespan.
10. Side Bolts and Nuts: Fasteners that secure various components together, ensuring proper assembly and stability.
11. Hose Connections: Hydraulic hoses that connect the excavator's hydraulic system to the hydraulic breaker, delivering the necessary hydraulic power.
Price range of excavator breaker parts
The price range of excavator breaker parts can vary depending on several factors, including the manufacturer, model, size, and specific part being purchased. Here are some general price ranges to give you an idea, but please note that these are approximate figures and can vary significantly:
1. Chisels or Tools: The price range for chisels can start from around $100 and go up to several hundred dollars, depending on the size, type, and quality.
2. Pistons: The cost of replacement pistons for hydraulic breakers can range from $200 to $800 or more, depending on the size and specifications.
3. Front Heads: The price of front heads can range from $500 to $1,500 or more, depending on the size and compatibility with the specific excavator and breaker model.
4. Seals and O-rings: The cost of seals and O-rings can vary depending on the specific part and quantity needed. Prices can range from a few dollars for individual seals to tens or hundreds of dollars for seal kits.
5. Wear Parts: The price range for wear parts such as wear plates, bushings, and rings can vary widely depending on the size, material, and specific requirements. Prices can range from $50 to several hundred dollars or more per part.
It's important to note that these price ranges are approximate and can vary significantly based on various factors, including the quality, availability, and the specific supplier or manufacturer you choose. Additionally, labor costs for installation or any additional services may also need to be considered.
For accurate and up-to-date pricing, it's recommended to contact authorized dealers, excavator parts suppliers, or manufacturers of hydraulic breaker parts. They can provide you with detailed information and pricing specific to your requirements.
