With the development of our country in recent years, construction machinery is used more and more frequently. In particular, some high-power equipment, such as excavators and other products, has great help to infrastructure construction. In order to make it more powerful, many operators who use excavators want to consult about the use of the extended arm of the excavator. Today Xiaobian wants to share some common problems with you.
1. What kind of excavator can be refitted into an elongated arm excavator?
不建议对新机器进行改装，因为改装后对臂式挖掘机进行加长，会增加挖掘机的负荷，而且容易与原厂发生售后服务纠纷，没有保修期限。不建议修改机器不到50%新,因为机器的使用寿命相对旧的,各方面性能下降,和延长臂本身有一定的重量,很难充分发挥效率的加长臂挖掘机,最好是将5 - 8新挖掘机加长臂挖掘机。
It is not recommended to refit the new machine, because lengthening the arm excavator after refitting will increase the load of the excavator, and it is easy to have after-sales service disputes with the original factory, and there is no warranty period. It is not recommended to modify the machine less than 50% new, because the service life of the machine is relatively old, all aspects of performance decline, and the arm itself has a certain weight, it is difficult to give full play to the efficiency of the arm excavator, it is best to 5-8 new excavator arm excavator.
Second, using an extended arm excavator?
The outrigger of the excavator has two outriggers and three outriggers. The lengthened arm of two-stage excavator is mainly suitable for earthwork foundation, deep foundation pit excavation and river dredging. The telescopic arm of three-stage excavator is mainly used in the demolition of high-rise buildings and other projects. According to the lever principle and mechanics principle, the force of the extended arm excavator is smaller than that of the original excavator, and the heavy construction site should be avoided as far as possible.

3. How does the telescopic arm of the three-stage excavator demolish the building?
It mainly depends on the discretion and decision of the building. The bottom of some mud or industrial waste must be transported first so that the straight hammer of the excavator can reach the roof; after the excavator has been loaded, enough turning space is needed to stabilize it.
4. Structure of telescopic arm of excavator:
The working arm of the long arm excavator, the extended arm cylinder, the oil cylinder, the working arm, the excavator bucket cylinder and other components are characterized by: in the body support, the connection of the extended arm, the connection of the lower arm cylinder, the movement of the front end of the extended arm through the pin shaft and one end of the working arm, and the installation of an arm cylinder between the working arm and the extended arm.
