The transportation of steel pipes in tunnels is the first issue to be considered. At present, the transportation, unloading and installation of inclined sections, inclined shafts and flat sections of hydropower stations are generally carried out using transport trolleys.

[0003] In the existing public documents, the patent publication number CN216580490U discloses a transport trolley device suitable for large pressure steel pipes. The trolley is easy for workers to disassemble or assemble. At the same time, the device has the advantages of low price and reduced design cost. It can be used for the transportation of pipes with different diameters.
