Why Construction Demolition Projects Can’t Do Without Excavator Breaker Machine?
With the acceleration of urbanization, high-rise demolition and road reconstruction projects are everywhere. Traditional blasting methods are strictly controlled, and excavator breaker machine has become the preferred equipment for demolition projects due to its safety and efficiency:
- Completely replace secondary blasting: In mining areas and quarries, hydraulic rock breaker machine is widely used for secondary crushing, breaking large blasted ore into transportable sizes, and completely eliminating the safety hazards of secondary blasting.
- Wide application range: In addition to mining, this equipment can also be used for mining, crushing and demolition operations in metallurgy, railways, highways, construction and other fields. It can easily handle both hard granite and reinforced concrete structures.
How to Choose a High-Quality Excavator Breaker Machine?
Faced with a wide range of excavator rock breaker for sale information on the market, how to choose a durable device? The quality identification of the following three core components is particularly crucial:
- Cylinder material: High-quality hydraulic rock breaker adopts high-strength steel plates manufactured by special precision technology, which can enhance heat resistance and wear resistance. Inferior cylinders are prone to cracks under long-term high-frequency impact, leading to hydraulic oil leakage.
- Piston design: The extended impact piston can increase striking force while reducing recoil, effectively reducing the reaction force on the excavator. This not only protects the main machine but also extends the service life of the breaker itself.
- Oil seal structure: High-quality oil seals will add an oil return channel design on the pressure-bearing surface, which can significantly reduce oil seal pressure and improve oil seal service life. This is an important basis for judging whether the hydraulic rock breaker price is reasonable.
Advantages of YG Excavator Breaker Machine
YG series products have many outstanding advantages in design and manufacturing:
- Energy-saving and low-noise design: The effective combination of shock-absorbing rubber pads and sealed boxes greatly reduces the noise level during equipment operation, meeting the requirements of environmentally friendly construction and reducing operator fatigue.
- Stable hydraulic power unit: Equipped with a high-performance hydraulic power unit, ensuring stable working performance and high work efficiency. No matter how hard the rock is, it can maintain continuous and strong impact force.
- Advanced energy storage technology: The stable and reliable accumulator perfectly cooperates with the oil circuit reversing system, allowing the piston to always maintain a good operating state and ensuring that each strike is accurate and powerful.
Correct Usage Methods and Precautions for the Hydraulic Rock Breaker Machine
Owning a high-quality device is only the first step; correct usage methods are equally important:
- Choose the right chisel: Select the matching chisel diameter according to the rock hardness. As can be seen from the parameter table, different models of hydraulic rock breaker machine correspond to different chisel diameters, ranging from 35mm to 210mm, which must be strictly matched.
- Control the striking direction: Avoid empty striking as much as possible, and the chisel should always be perpendicular to the working surface. Inclined striking is not only inefficient but also prone to chisel breakage and cylinder wear.
- Reasonably adjust flow and pressure: Precisely adjust the hydraulic output of the excavator according to the hydraulic oil flow and operating pressure range in the parameter table. Excessively high flow will damage the breaker, while excessively low flow will fail to exert its due effect.
Frequently Asked Questions About Excavator Breaker Machine
Q: How to match the excavator with the hydraulic rock breaker model?
A: Select the product with the corresponding chisel diameter according to the excavator tonnage, refer to the “Suitable Carrier Weight” column in the parameter table, and avoid matching a small breaker with a large excavator or a large breaker with a small excavator.
Q: Is the higher the striking frequency, the better?
A: Not necessarily. As can be seen from the parameter table, small-sized equipment can have a striking frequency of 800-1300bpm, while large-sized equipment only has 150-400bpm. This is because large equipment has high single impact energy and does not require high frequency. Choosing the appropriate striking frequency can achieve the best crushing effect.
Q: What if the hydraulic rock breaker has weak striking force?
A: First check if the nitrogen pressure is sufficient, then check the hydraulic oil flow and pressure. If the bushing clearance is too large, replace it in time.
Q: What factors affect the hydraulic rock breaker price?
A: It mainly depends on the model tonnage, core component materials and rotation function. YG series products have outstanding cost performance. For specific quotations, please consult customer service.
