1．组织管理体系Organization management system1.1 现场吊装组织机构Suspending organization on site部分章节示例如下：50万吨/年乙苯/苯乙烯装置属于新建项目，整个装置作业面开阔。

装置界区达180米×120米，因此场地环境较好，有利于进行大型设备的吊装作业另外装置内道路按照设备进厂、1250吨履带式吊车行走及吊装对地面承载力的要求进行施工500,000t/y Plant is a part of new projects, the whole installation site is wide and its boundary is 180 m*120 m, so the environment is better for suspending heavy facilities. Otherwise, roads inside installation site construction is in accordance with facilities entering factory, 1250ton pedrail moving route and requirements of ground bearing for suspending.

4.3.3 卸车原则上采用以下方法：Unloading adopt the following measures in principle:1）充分考虑设备进入现场与其吊装时间的逻辑关系，尽量直接从拖车上卸货及吊装。

Consider the logical relationship of entering onsite and suspending time for facilities sufficiently, try best to unload and suspend directly from the trailer.

2）大型设备根据合同由运输方直接运输至现场指定位置According to the contract, heavy facilities should be deliveried by transport side directly to the appointed places。

3）较小型设备直接运输至现场后，采用250吨履带吊直接卸车或吊装Use 250ton pedrail crane Model 250 to delivery or suspend directly after the smaller facilities being deliveried on site.。

4）如果设备卸于临时库房，则根据设备重量、规格尺寸等条件采用160吨汽车吊单车或160吨汽车吊与130吨汽车吊双车抬吊的方法将设备装车，封车后运输至现场，采用160吨汽车吊单车或160吨汽车吊与130吨汽车吊双车抬吊的方法卸车。

If delivery the facilities in a temporary storeroom, use 160ton auto suspending single vehicle 160 or 160 ton auto suspending and 130ton auto suspending twin vehicles lifting to install the vehicle, close the vehicle then delivery on site in accordance with conditions of fcilities’ weight and specification then adopt the measures of unloading facilities by 160ton auto suspending single vehicle or 160ton auto suspending and 130 ton auto suspending tiwn vehicles lifting.

5）设备支点用4个支撑垛支撑每个支撑面积9平方米（每个支撑垛下面铺设δ30~40mm钢板）The facilities pivot support by the four supporting buttress. Each can support the area of 5 square meters (lay 30~40mm stell plank under each buttress).。

支撑鞍座利用设备运输的鞍座Use the deliverying bicycle saddle of the facilities to support the saddle.2）工程特点 Project characteristics。

苯乙烯装置吊装工程大型设备较多，分布面广其中100吨以上的设备17台：最大吊装重量的设备为乙苯蒸汽过热器/中间压力沸热换热器/低压沸热换热器，重量达679吨吊装总负荷740吨；最高设备为EB/SM分离器高度为80.8米，为本次设备吊装的重中之重。

Suspending project of Ethylbeneze& Styrene Plant has many heavy facilities distributed in a wild area. 17 sets of these are more than 100ton: the weighest suspending facility is Ethylbeneze steam heat filter/ middle pressure boiling exchanger/ lower pressure boiling exchanger, which is about 679ton and suspending bearing of 740ton; The highest facility, also the heaviest in all facilities, is EB/SM separator about 80.8meter

8.2.2 总体方案概述 General of whole scheme1）对于苯乙烯装置的设备吊装特点来说，采用机动性好的吊装机具能适用于重型设备多而分布较广的特点同时为使吊装工期尽量缩短，国内最大起重能力的1250吨履带式起重机的引进，给我们用于苯乙烯装置大型设备吊装的机具注入了新的内容。

For chatacteristics of Styrene facility suspending, using good flexibility suspending machinery can apply to facilities’ characteristics of quantity and distributeing wildly. 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 Styrene Plant.

2）经现场勘察和反复论证，兼顾了技术上的先进性，安全上的可靠性和经济上的合理性，在赛科苯乙烯装置大型设备的吊装工程中，我们决定采用大型移动式起重机作为主吊机具的总体方案，即履带式起重机主吊，M250型250吨履带起重机抬尾配合。

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 is the main suspending machinery and 250 ton pedrail crane Model 250 cooperate with lifting the trail.

3）根据合同，所有大型设备应运抵指定的吊装位置、方向、角度及高度卸车，并且直接利用设备出厂装车原支撑鞍座位置进行支垫According to the contract, all heavy facilities should be deliveried and unloaded to appointed suspending place, direction, angle and height, and underlay directly facilities in the original supporting saddle points as the facility leaving factory.。

4）所有塔类设备尽量在地面完成附件安装（包括附塔管道、梯子、平台、绝热防腐）然后吊装，吊耳以上部分妨碍吊装绳索及设备摆放支撑处的附件在塔吊装后施工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）塔顶部大口径管道因吊车的有效吊装高度所限，不能随塔吊装，在其吊装后，再用吊装此管线Big caliber pipeline is limited in height because of its available suspending height and could not suspend with the tower freely. After suspending it, install this pipe cable.。
