500,000t/y Ethylbeneze &Styrene 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 Model DEMAG CC8800 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，尽量使用CC8800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 use CC8800 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M250型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.
If delivery the facilities in a temporary storeroom, use 160ton auto suspending single vehicle Model KMK5160 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.
Suspending project of Shanghai SECCO 500,000t/y 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 (35-E-3004/3006/3007), which is about 679ton and suspending bearing of 740ton; The highest facility, also the heaviest in all facilities, is EB/SM separator. (35-T-4001) about 80.8meter
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 Shanghai SECCO Styrene Plant.
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.
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.
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.
T-4001 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.
