I believe that many large excavator users will encounter a headache when purchasing excavator ripper boom. There are so many rock arm manufacturers in the market, how should they choose the rock arm?

As a salesperson in the construction machinery industry, here are some things you should pay attention to when purchasing a rock boom.

 

 

  1. Generally speaking, the working conditions of the excavator are very harsh, so there are quite high requirements for the material of the rock arm of the excavator. Usually regular manufacturers will use high-strength steel for new production, and the preferred material is mainly high-strength manganese steel Q345 or Q550D. Similar steel materials are stable, solid and durable, and have become the first choice for large-scale construction machinery manufacturing materials, but here HITEstill strongly recommends using Q345 materials, because this material has strong plasticity, and it is very important that Q345 materials have Good stretchability, the inside of the excavator ripper boom is filled with cement and iron blocks. In the hot summer, when the internal material heats up and shrinks, the Q345 material can completely wrap the internal material well;

 

  1. The purchase of the excavator ripper boom needs to be customized according to the size of the excavator. At the same time, during the modification process of the rock arm, concrete and iron sand will be added to the big and small arms to increase the weight of the excavator arm, thereby increasing the excavation force. Can overcome more harsh working environment.

 

 

  1. Which manufacturers do excavator ripperboom well? Which manufacturers have the most cost-effective excavator rock boom?

At present, there are many manufacturers who can make rock arms. The technical content of the appearance of the rock arm is not very high. A small workshop can make it after some imitation, but some details and force analysis may not be in place. It is not cheap to make a complete set of rock arms, so users are advised to find out before placing an order. From the details of workmanship and welding, you can know how well the factory is doing.

 

  1. A brief introduction to the excavator ripper boom.

The excavator ripper boom is also called the olecranon arm, which is specially designed for processing weathered rock and shale. Under normal circumstances, the ripper of the standard arm cannot work, and the working efficiency of the breaker is relatively lower than that of the ripper. Low, unable to meet engineering needs and create greater profits. For the work of the rock arm, because the overall arm is shortened and heavier, the digging force of the excavator can be greatly increased, and it can overcome the harsher working environment.
