The elongated arm excavator is equipped with an elongated arm between the body bracket and the working arm. The elongated arm is supported and connected by the crude oil cylinder, and a working arm cylinder and the excavation bucket cylinder are installed on the elongated arm.
In and out of the cab, a set of cylinder operating system is installed correspondingly, which can expand the scope of the excavation bucket more than twice and reach a higher, deeper and farther range with the help of the telescopic operation of the operating arm cylinder and the excavation bucket cylinder. It is especially used to mine, wharf, warehouse, flood fighting and rescue and special occasion operation, which is a breakthrough transformation of excavation machinery. It has great practical value.
Classification of Extended Arm of Excavator:
The lengthened arm is mainly used for river dredging, port construction, metro construction and construction base excavation. By installing the lengthened arm on the base of the original excavator, the distance between the standard arm and the standard arm can be achieved, so that the excavator can maximize its use and be widely used in various construction sites, making the efficiency and safety higher.
The two-section elongated arm can be extended to (13-26) m, which is mainly suitable for earthwork foundation and deep cutting, long-distance dredging and excavation, and the three-section elongated arm can be extended to (16-32) m, which is mainly suitable for the disassembly of high-rise buildings and other projects. Generally speaking, the working equipment of the excavator's elongated arm includes the boom, bucket rod, bucket and related cylinders and hydraulic pipelines.
Because the replacement of the working equipment part of excavator is convenient, the corresponding working equipment can be replaced according to different working occasions to meet the needs of various working conditions.
For example, the whole operation equipment can choose the lengthened arm, so that the excavation scope of the excavator increases, and the mining rock excavation with high intensity needs to select and install the thicker boom bucket rod to deal with the harsh working conditions to ensure the smooth completion of the project.
The above information is that our long arm excavator is organized and released. We hope to help you with our website: http://www.rbaras.com!
