The Ultimate Guide for Customers to Buy a Heavy-Duty Hydraulic Breaker for Excavation

Heavy-duty hydraulic breakers are essential tools for excavation, demolition, and mining projects. They are commonly used for breaking hard rock, demolishing buildings, cutting through mountains, and performing tunneling or underground construction.

For such demanding applications, customers should consider Beilite’s BLT-210 to BLT-280 series hydraulic breakers. These models deliver powerful impact energy and exceptional efficiency for large-scale breaking operations. Each series is compatible with excavators, loaders, or backhoes of specific tonnage ranges, typically between 70 and 200 tons. It’s important to match the hydraulic breaker’s rated tonnage to the carrier machine’s tonnage to ensure safe and efficient operation. If you are unsure which model suits your excavator, you can always contact a Beilite agent or the factory for assistance.

Beilite heavy-duty breakers can also be customized according to working oil flow, relief pressure, operating pressure, impact rate, and chisel length - key parameters that determine their performance and suitability for excavation tasks. Below, we will provide a comparison table of two Beilite BLT series models for reference.

Does the Tonnage of a Hydraulic Breaker Matter for Heavy Rock Demolition?

Yes, tonnage plays a critical role. Breaking heavy rock or reinforced concrete efficiently requires a hydraulic breaker with sufficient weight and impact power. The breaker and the carrier (excavator or loader) must be properly matched to ensure stability, performance, and equipment longevity.

For example, the BLT-245 series is designed for 90–130-ton excavators or loaders. The top-mounted BLT-245 has a length of 5,186 mm, a weight of 13,170 kg, and operates at 300–330 bar working pressure combination that delivers massive breaking power and high operational efficiency.

Is Matching the Carrier to the Hydraulic Breaker Necessary?

Absolutely. Carriers such as excavators, loaders, and backhoes are classified by tonnage ranging from mini to medium to heavy-duty. Each breaker must match its carrier according to the manufacturer’s specifications. Choosing the right breaker for your carrier ensures balanced performance, reduced wear, and maximum productivity based on the project’s size and difficulty.

Maintenance Requirements for Heavy-Duty Hydraulic Breakers

Proper maintenance is essential to extend the service life of your hydraulic breaker and maintain consistent performance. Follow these key maintenance steps:

1. Keep the breaker clean and free from dust or dirt before use. Wipe components with diesel for cleaning.

2. Maintain and grease all seal kits and components regularly, using proper tools.

3. Always release the gas in the back head completely before performing maintenance.

4. Inspect hydraulic pipes for leakage every 2 hours.

5. Grease the chisel, chisel bush, and thrust bush every 2 hours.

6. Every 10 hours, check the gap between the chisel and bush, inspect for wear, and tighten bolts on the breaker and accumulator.

7. Every 200 hours (or monthly), check the breaker’s working pressure, relief valve, and oil quantity.

8. Every 600 hours (or every 3 months), conduct a full inspection—check all bolts, hydraulic lines, cracks, and replace return oil filter elements if necessary.

9. Regular maintenance helps prevent costly downtime and ensures safe, efficient operation.

Period of wear parts replacement

Hydraulic Breaker Chisel Replacement

The service life of the chisel depends on how it is used. Vertical operation offers the best efficiency and durability, while prolonged horizontal use may reduce striking power and cause chisel damage. When there are gaps between the chisel bush and chisel, the piston may strike inaccurately, potentially damaging the cylinder and piston. Replace worn components such chisel bush, chisel, and thrust bush promptly to avoid further damage.

If you are using a Beilite hydraulic breaker, always use genuine Beilite chisels to ensure compatibility, efficiency, and long-term reliability.

FAQs

1. How do I choose the right Beilite hydraulic breaker for my excavator?

Select a hydraulic breaker that matches your excavator’s tonnage and hydraulic capacity. Beilite provides models from the BLT-40 to BLT-280 series, suitable for 0.5 to 200-ton carriers. Always check compatibility based on working pressure, oil flow, and intended application, or consult a Beilite representative for expert assistance.

2. How often should a hydraulic breaker be serviced or maintained?

For optimal performance, basic inspections such as checking for leaks, greasing the chisel, and tightening bolts should be done every 2 to 10 working hours. More detailed inspections, including pressure checks and filter replacements, should occur every 200 to 600 hours, depending on usage intensity and site conditions.

3. What type of chisel should I use with my Beilite hydraulic breaker?

Always use genuine Beilite chisels to ensure maximum efficiency, safety, and longevity. Chisel type and length should match the application pointed chisels for rock breaking, flat chisels for concrete, and special designs for trenching or tunneling. Using non-original parts can affect performance and void warranty coverage
