                It is not recommended to modify the new machine because after being modified into an extended arm excavator, the excavator load will increase, and it is also easy to have after-sales service disputes with the original factory if the warranty period is not expired; It is not recommended to modify machines below 50% new, as the service life of the machine is relatively old and its performance is reduced in all aspects. In addition, the extended arm itself has a certain weight, making it difficult to achieve the efficiency that an extended arm excavator should have. The best option is to convert an excavator that is 50-80% new to an extended arm excavator
                Scope of use of excavator extension arm
                The extension arm of the excavator includes a two-stage excavator extension arm and a three-stage excavator extension arm. The two-stage excavator extension arm is mainly suitable for earthwork foundation and deep cutting excavation operations, as well as river dredging; The three section excavator with an extended arm is mainly suitable for demolition and other projects of high-rise buildings. According to the principle of leverage and mechanics, the force on the extended arm excavator is reduced compared to the original, and it should be avoided to carry out construction in heavy work situations as much as possible.
                How to demolish a building with a three stage excavator and an extended arm?
                It mainly depends on the height of the building, for example, demolishing a 5-story building:
                1. Some mud or industrial waste must be transported to the bottom first, so that the excavator can reach the top of the building with a straight impact hammer.
                2. After the excavator is loaded with the filling material, make it stable and leave enough turning space.
                3. Use an impact hammer to hit the wall vertically inward (about 1 meter from the top), open a hole in the wall, and push the debris inward to prevent it from falling and hitting oneself.
                4. Expand the hole without moving the beams and columns. After opening the brick wall, hit the pillar, so that if the beam on top cannot support it, it will fall inside, ensuring one's own safety. In this order, advance from top to bottom and inward
