March twenty seventh，SANY 3600-ton crawler craneSCC36000A，Complete the steel containment vessel of Unit 1 of Guangdong Lianjiang Nuclear Power Phase I Project（CV）The first ring of the cylinder was successfully hoisted in place.，Important engineering nodes of project realization。

Steel containment isCAPMain equipment of 1000 nuclear power unit，From the bottom head、Cylinder from the first ring to the third ring、Top sealing head consists of five module，It is the third safety barrier of the nuclear island reactor plant.。The weight of the first ring of the cylinder is 883 tons.，Gross shipping weight 945.3 tons，The total hoisting weight is about 1010 tons.。

Guangdong Thermal Power Special Company is responsible forCVTransportation of one ring of cylinder、Lifting task。

CVThe first ring of the cylinder is used as an annular cylinder module which is firstly positioned.，With large overall load、Features of high installation accuracy。The equipment is heavy、Easy to deform、The transportation center of gravity is high，And that vehicle enter range is limited.，Modular transport vehicle assembly time is tight、The task is heavy。

March 26 5:20，CVThe first ring of the cylinder is transported from the workshop.，Pass bySPMTJacking、Fixed、Transportation and other processes，At 8:00 Transportation to the lifting parking point，Transport distance 930m，Via 2 right-angle bends，1 hour and 24 minutes。

March 27 14:13，CVFormal lifting of the first ring of the cylinder，SCC36000ASlowly lift it away from the transport vehicle，At 17:17 Successfully hoisted in place，After three hours and four minutes.。

This hoisting，The time for the crane to enter the hoisting site is short.，The super-lift counterweight is limited by ground pressure and needs to be increased successively before hoisting.，It is difficult to install，In addition，CVThe volume of the first ring of the cylinder is large, and the thickness of the lower opening cylinder wall is only 47.6 mm，It needs to be hoisted overCA20 top of the module，Precise placement on the bottom head，The overall operating radius is far，It is difficult to level the center of gravity。

Through the joint efforts of project personnel，Final，SCC36000AHigh-quality realization of one-time accurate positioning of No.1 nuclear island cylinder，The whole process is safe、Smooth、Orderly。
