Lately，SuccessionSichuan Section of UHV Harbin-Chongqing RailwayIntroductionSAC800C7-8All terrain crane，Guangdong 500kVBohe Power Plant 3、Unit 4 Entry ProjectAlso adoptedSAC800C7-8To take on 50kVInstallation of high-voltage line tower。

Project expansion Ehuang、Cloud City、Luodong, etc. 500kVSwitchyard，New Bohe Power Plant to Ehuang Station、Ehuang station-Yuncheng Station and other four double-circuit lines，Total line length 2×335.4km。The project is located in the mountainous area of western Guangdong.，Peaks and forests are densely covered、The terrain is complex，It adds a lot of difficulties to the erection of the line tower.。

PurchaseSAC800C7-8Zheng Xinglong, General Manager of Yuexing Transportation in YunanThe introduction said：“The construction sites are basically in the mountains.，The slope is 40%many，The camber is small，A lot of turns are 180.°。The reason for choosing this car is that it has strong trafficability.，All-wheel steering，The turning radius is small，With three differential locks，Basically, all the slopes here can be climbed.。”

AdoptSAC800C7-8，It ensures enough lifting capacity.，It also has good traffic capacity and site adaptability.，Reduce damage to forest land，It reduces the pressure of the follow-up work of reforestation.，Save investment related to engineering construction，Achieve efficient construction、Low consumption。

This kind of temporary mountain road，It's not just a test of equipment.，It is also a big challenge to the driver's psychology and technology.。

12.3mShort body，All-wheel steering、Full bridge drive，Minimum Turning Radius 6.5m，Comparable to an ordinary car；276kWEngine、Hydraulic-loaded retarding gearbox、525/80R25 tires，The uphill is strong、It's safe to go downhill，MakeSAC800C7-Deal with the winding and rugged mountain road calmly。

HType leg layout，Longitudinal/Span 7.45×6.4m，Flexibility to face the challenges of working in narrow spaces。

Vehicle remote control，Cloth car、Work more easily and efficiently。

In the past，Small-tonnage all-terrain cranes are mostly found in developed countries in Europe and America.。With the progress of China's economic level and the development of infrastructure,，The requirements of construction projects for construction equipment are getting higher and higher.，Uch as minimizing environmental impact、Pay more attention to construction safety、Pay attention to construction efficiency and comprehensive cost……SAC800C7-This kind of equipment, which is suitable for subdivision, has also begun to come into everyone's sight.，Selected by domestic hoisting enterprises。

From a donkey pulling a man to opening a way to open a field，From truck crane to the whole ground，The changes in the construction methods of transmission towers in mountainous areas reflect the achievements of China's economic construction.，It also reflects that domestic hoisting enterprises are becoming more specialized.、High-end transformation and development trend。
