Sany Heavy Industry: All-round Deputy, Ace Partner! Telescopic arm crawler crane can also dominate the wind field

With the successful assembly and butt joint of the segments of the mixing tower at position 14,，The first mixed tower Wind Turbine of Guoneng Lingbi 70 MW wind power project has been hoisted。TrinitySCC15000TMThe Crawler Crane is used as the main crane。

The wind farm is located in Suzhou City, Anhui Province.，The plain area is low-lying。However, the construction time is in the rainy season.，The rain never stops，As a result, the construction area is prone to water accumulation，The muddy and soft soil makes the approach and transfer of the main crane a difficult problem.。

In order to solve this problem,，The construction party has found it.STB1600T6 Telescopic arm Crawler CraneAs a helper。

Operator Huang Shifu introduced.：“Generally speaking，Truck_crane/ 'target='_blank' style='color:blue;'>Truck Crane、The Crawler Crane can be used as the auxiliary crane for wind power hoisting.，ButPoor site adaptability of traditional Truck_crane/ 'target='_blank' style='color:blue;'>Truck Crane，The approach needs to repair the road、Lay steel sleepers，It is impossible to continue construction when encountering muddy road sections.，Move one after another beyond the scope of operation、Hit the legs，It takes a long time，It greatly affects the construction efficiency。”

“ If Crawler crane with truss arm，The boom needs to be removed during the transition.、Remove the counterweight，And transport，A worker can't finish the work at all.，It takes time, effort and money.。In contrast，Telescopic crawler cranes are the ideal choice，It is not afraid of muddy roads.，It can walk with load，A worker can complete the transition.。”

It has entered the market since August this year.，STB1600T6 performed very well，With its help.，Construction efficiency has been greatly improved.。

Mr. Xu, the construction manager, said.：“AtSTB1600T6 Before approach，The auxiliary cranes are two truss arm crawler cranes.，When dismounting the counterweight of the main lifting equipment，The arm length of these two devices needs to be converted.，The telescopic boom crawler crane can be hoisted by directly extending to the appropriate length.，You can save an hour and a half.。”

◼︎ And that work condition is more comprehensive

One equipment and one Vehicle are used as two Vehicles.，Be able to take care of the disassembly and assembly of the main crane、The tower tube slips to the end、The impeller slips、Four tasks of blade support，Achieve full coverage of typical working conditions。

◼︎ Construction is more efficient

Vehicle self-loading and unloading，No need to disassemble the boom，No need for outriggers，Reduction of one auxiliary worker。

◼︎ Hoisting is more powerful

Auxiliary kiloton main lifting and unloading vehicle，19XThere is no pressure for the blade to slip.，Compared with the same type of products of the same tonnage，More capable。

◼︎ The transition is more convenient

The main engine weighs 79.4t，Retracted width 3.5m，The whole machine can be transported by 3 vehicles.；Intermediate rail 4.5m，Self-transfer with counterweight in the field，2kmDistance is only 1h。

With the full cooperation of all parties,，The project ushered in“A good start”。After the completion of the wind farm，The theoretical annual power generation is 249.22 millionkW·h，Annual on-grid electricity 180.94 million kW·h，Annual utilization hours 2585h，It can effectively improve the ecological environment、Reduce carbon emissions，Promoting local economic development。
