The invention discloses a boom
system which comprises a boom and a conveying pipeline. The boom comprises a first arm, a middle arm and a
tail arm which are hinged sequentially, the conveying pipeline comprises a first pipeline body, a middle pipeline body and a
tail pipeline body which are fixedly arranged on the first arm, the middle arm and the
tail arm respectively and are connected sequentially, the middle pipeline body comprises a first pipeline, a second pipeline and a pipeline switching device, an inlet of the first pipeline is communicated with the first pipeline body, an outlet of the second pipeline is communicated with the tail pipeline body, and the pipeline switching device is used for disconnecting or connecting the first pipeline with the second pipeline. The boom
system is provided with two discharging ports used for long-distance distribution and short-distance distribution respectively, and harm caused by 'bypassing' of concrete in the conveying pipeline during short-distance distribution can be avoided. Additionally, the invention further discloses the conveying pipeline and operating equipment provided with the boom
system.
