80 Tons on the Ground to Support 800 kV UHV Construction of Harbin-Chongqing Railway-Sichuan Section

As an important province of UHV construction in China，Several UHV lines in Sichuan、Substation construction is active，It has also imported a kinetic energy into the hoisting market.。Lately，Another all-ground new modelSAC800C7-8 Join the team，In Hami-Sichuan Section of Chongqing 800 kV UHVDC Transmission Project，Undertake 70mInstallation task of height line tower。

According to introduction，192 line towers are expected to be built in this section.，58, respectivelymAnd 68mTwo heights。The geographical environment is changeable、Multiple crossings of 35 kV transmission lines、High speed/Railway line of communication，It is a great challenge to the construction.，There are also more restrictions on the selection of lifting equipment。In particular, the base is mostly in the mountains.，“Extremely high requirements for the trafficability of lifting machinery。Pavement width is only 3m，“U、V”There are many shapes and bends，It is difficult for a car with many bridges to pass.，The hoisting performance of less axles can not be satisfied.，SAC800C7-8 solves these problems well.。”This is the introduction of the project supervisor of Guang'an Section.。

Lifting height 58m / Operating range 17.5m / Weight 2.8t

The total length of Sichuan section of Harbin-Chongqing Railway is 291.6km，561 new iron towers，The line runs through the east of Sichuan.，It passes through mountains along the line、Forest area、Icing area，The natural environment is complex、There are many intersections and spans。

Sichuan is a major province of hydropower transmission in China.，It is also an important energy base in the west.，“Fourteen five”Period study、Planned UHVDC project，It will be connected with the Northwest Power Grid to form the second channel.，As well as the continuous transfer of hydropower from the lower reaches of the Yarlung Zangbo River to Sichuan，Keep“Power transmission from west to east”Continuous transmission of clean power through large channels。
