The expressway from Lankao to Shenqiu is an expressway in Henan Province.“13445 engineering”One of the 16 north-south longitudinal corridors。After the completion of the project, a new longitudinal encryption channel will be formed between Daguang Expressway and Yangxin Expressway.，Further improve the road network layout of Daguang Corridor。

The route length of Lankao section is 15.Three kilometers，Adopt two-way four-lane technical standard，Design speed 120 km/Hour。Yingfeng Construction Engineering Co., Ltd. of Lankao County and Zhengzhou Zhongliang Machinery Equipment Leasing Co., Ltd. undertook the construction of bridge erection and hoisting in this section.，AdoptSAC2200TAndSAC2000C8 Carry out lifting operation。

220 and 200，They are all classic models of Sany.，The first domestic five-bridge 220-ton all-terrain crane was born in Sany.。AndSAC2000C8 as soon as it is available，It is sought after by the industry.，Newly launched in 1924SAC2000C8-8，It has once again become a hot spot for 200-ton all-ground.。

SAC2000C8 Operator indication，Its upper car uses non-four engines.，There is no need to add urea,And operation time is save，Operating fuel consumption decreased by 30 percent%；Excellent on-load transfer capability；Under the new hydraulic platform，How much torque does the engine have，How much can the pump use?，The efficiency improvement of heavy-duty operation is very obvious.，Maximize engine efficiency。”

The project requires that the quality of the project delivered must be excellent.，Extremely high requirements for safety performance。For the addition of SANY crane，The project unit and the workers on site are very satisfied.：“Sany large-tonnage crane is well-known in the industry.，Equipment performance is very stable，Work with tacit understanding，The working efficiency is greatly improved.，It also speeds up the project process.”。
