Meanwhile, to shorten the working time, 1250ton pedrail crane of the biggest lifting ability introduced in China inject new content to heavy facilities’ suspending machinery of Shanghai SECCO Styrene Plant.2） 經(jīng)現(xiàn)場勘察和反復論證，兼顧了技術(shù)上的先進性，安全上的可靠性和經(jīng)濟上的合理性，在賽科苯乙烯裝置大型設備的吊裝工程中，我們決定采用大型移動式起重機作為主吊機具的總體方案，即DEMAG CC8800型1250噸履帶式起重機主吊，M250型250噸履帶起重機抬尾配合。 According to the reconnaissance on site and demonstration repeatedly, we paid attention to advanced technology, dependable safety and rational economy, and decided to adopt the whole shceme of heavy jenny as the main suspending machinery, in which 1250ton pedrail crane DEMAG CC8800 is the main suspending machinery and 250 ton pedrail crane Model 250 cooperate with lifting the trail.3） 根據(jù)合同，所有大型設備應運抵FCC指定的吊裝位置、方向、角度及高度卸車，并且直接利用設備出廠裝車原支撐鞍座位置進行支墊。 According to the contract, all heavy facilities should be deliveried and unloaded to appointed suspending place, direction, angle and height by FCC, and underlay directly facilities in the original supporting saddle points as the facility leaving factory.4） 所有塔類設備盡量在地面完成附件安裝（包括附塔管道、梯子、平臺、絕熱防腐）然后吊裝，吊耳以上部分妨礙吊裝繩索及設備擺放支撐處的附件在塔吊裝后施工。 All the tower facilities try the best to install accessories on the ground（including attached tower pipeline,ladder,platform, adiabat and antisepsis）before suspending. The parts higher than suspending hole, where accessories obstruct suspending lines and places to put suppoting facilities, should construct after suspending tower. 5） T4001塔頂部大口徑管道因吊車的有效吊裝高度所限，不能隨塔吊裝，在其吊裝后，再用CC8800吊裝此管線。 T4001 big caliber pipeline is limited in height because of its available suspending height and could not suspend with the tower freely. After suspending it, use CC8800 to install this pipe cable. 大型設備吊裝施工工藝 Construction techncis of suspending and installation of heavy facilities 設備參數(shù)表 Parameter form of facilities序號Ref No..位號No.名稱Name規(guī)格（m m）Stardard設備吊裝重量明細（t）Details of suspending weight本體Noumenon平臺Platform絕熱Heat insulation配管Attached pipe吊裝重量Weight1D3001乙苯/蒸汽分離罐Ethylbeneze/steam separate tankf7000180。126001080005521202E2001A/B苯塔再沸器Reboiler of Beneze tower880001410101223E3004/3006/3007乙苯蒸汽過熱器/中間壓力沸熱換熱器/低壓沸熱換熱器Ethylbenezesteam separater/middle pressure boilingchanger/lower boiling changerf5500180。350006790006794E4009苯乙烯塔冷凝器Styrene tower condesator1072401075R1001烴化反應器Alkylation reactorf2600180。256357590010971026R3001第一脫氫反應器The first dehydrogen reatorf5200180。299732680002687R3002第二脫氫反應器The second dehydrongen reactorf5900180。353155000005008T2001苯塔 Benzene towerf4500180。414651400002325302189T2003乙苯塔Ethybeneze towerf3000180。448007153014161611810T4001EB/SM分離器EB/SM separatorf7600180。8078056010023141060511T4003苯乙烯塔Styrene towerf4800180。3848010515202016012E4003A/B/CEB/SM冷凝器EB/SM splitter condenser f3600180。1164114670014670013E3009A/B冷卻器TRIM COOLERf2700180。14194123800123800注：1) ）《大型設備一覽表》。Remarks: see Form of heavy facilities in Section , item 3) about shell weight reference of facilities
