Sany Heavy Industries: Shocking! Two kiloton equipment are lifted by two cranes!

Recently，MCC5's Hebei Huafeng Coke Oven Flue Gas Treatment Project Site，SCC17000TMAndSCC15000TMOnly 7 hours.，Successfully completed the hoisting of the main truss on the side of No.6 coke oven machine in No.1 Branch Plant，For production、The stability of the furnace body provides a powerful guarantee.。

Outside the slide line of the coke pusher track at the side of No.6 coke oven and the mountain、Clear distance of pipe rack 8.9 meters，Not only is there not enough site for assembly of hoisting equipment，There is not enough space for hoisting.，It is impossible to adopt the previous hoisting scheme.，Therefore, the difficulty of construction is doubled.。Other than that，In order not to affect production，The owner only gaveThe interval of 10 hours is taken as the hoisting time.。

Time is tight and the task is heavy.，Construction deployment and scheme planning in the early stage are more important.。

For this reason，The project department and the expert group will work together with the construction team、Professional engineers and operation technicians of hoisting machinery have carried out many discussions and innovations on the hoisting scheme.，Use at the same timeBIMTechnology，The environmental parameters and the whole process of hoisting were simulated.，Dynamic analysis of the sliding contact line between the steel truss and the sliding contact line under each working condition when the steel truss goes around at high altitude、Collision condition of coke oven body，Optimize operation steps and selection of Crawler Crane。

Finally, it is determined to pull the truss section by section outside the slide line of the coke pusher.、Assembly and assembly、Overall adjustment、One-time molding，An end table is arranged between the slide wire of the coke pusher and the coke oven body.SCC15000TM，One set shall be set in the room.SCC17000TMCarry out double-machine lifting。

From the beginning of February this year，The project department began to plan the walking route of the Crawler Crane.，The foundation of the hoisting station shall be treated and the traveling platform shall be set up.。Assemble the truss to be hoisted in the middle of March，Complete the integral forming and quality inspection of the truss by the end of April。April 25，Two sets of super-large tonnage Crawler Cranes began to enter the site for assembly.，Hoisting capacity available on May 6。

May 7, 9 a.m.，Hoisting has officially begun。SCC15000TMAndSCC17000TMThe combined force will weigh 440 tons.、The main truss with a length of 120 meters is lifted to bypass the sliding line.，Upper space between tracks of coke pusher at arrival side，And then walk with a load，Adjust the lifting attitude，Stabilizing Truss。And then，SCC15000TMIncrease the counterweight to 370 tons，AndSCC17000TMLift the truss to the door-type support on the furnace roof together.，Achieve in place，Hoisting is completed。

This hoisting isIt is the first time for domestic coking enterprises to use large-tonnage crawler cranes to hoist super-large components under coke oven production conditions.，It is also the right of the MCC5 Group“Speed of Wuye、Wuye Service、Quality of Wuye”Full embodiment of。Future，Hebei Huafeng Coke Oven Flue Gas Treatment Project will also strive to become a high-quality project that can stand the test.，Set up a good monument in the industry。
