3、外无构成影响的障碍物。The deadweight of PRIMARY PRODUCT EXCHANGER（E3102）is 75t and the total weight of equipment to be lifted is 77t(including the weight of ladder platform) with a outline size of 3500mm9600mm.The equipment foundation is a framework foundation, and there are no other obstacles to lifting excep

4、t framework.2吊装方案的选择Selection of lifting scheme根据现场的条件及现有的吊装机具，吊装采用单台吊车提升、整体吊装的方法来安装，主吊车选用一台400t履带吊（德国的Liebherr LR1400型），另外还需用一台250t履带吊（日本的神户制钢 CKE2500型）辅助溜尾。According to the site conditions and the riggings available, PRIMARY PRODUCT EXCHANGER（E3102） will be lifted wholly by a single crane. A 400t

5、crawler crane (German Liebherr LR1400 type) will be chosen as main crane, and a 250t crawler crane ( Japan CKE2500type) as tailing. 3吊装的平面布置Lifting layout3.1吊装时主吊车、溜尾吊车的站车位置，详见下面的吊装平面布置图（图1）The positions of main crane and tailing crane when lifting are shown in the following lifting layout. (Sketch

6、1)图14吊车吊装工况的选用Selection of Operating Condition of the Cranes4.1 主吊车吊装工况的选用Selection of Operating Condition of the Main CranePRIMARY PRODUCT EXCHANGER（E3102）金属重量均为75t，设备保温2t,吊索具（包括吊钩、平衡梁、卸扣、钢丝绳等）的重量为5t，因此吊装计算重量应为：The metal weight of PRIMARY PRODUCT EXCHANGER（E3102）is 75t, equipment insulation 2t and

7、slings and rigging (including hook, spreader, shackles and wire ropes etc.) 5t. The total weight to be lifted is calculated as follows:G=75+2+5=82t选LR1400型履带吊的工况为：起重臂长70m，作业半径16m。在此工况下，吊车的额定起重量为104t，吊车的起重负荷率为=79%，其起重能力完全能满足吊装要求。The selected operating condition of LR1400 type crawler crane is as foll

8、ows: Boom length is 70m, operating radius 16m. The rated lifting capacity of the crane under this condition is 104t, the percentage of lifting load of the crane is =79%, which fully satisfies the lifting requirement.吊车吊装时的净高度计算参见下图（图2），The net height of the lifting is indicated in sketch 2.吊车在上述的工况下

9、，起重臂顶部滑车组中心距地面的高度为71.3m，吊装时的净高度h应为：Under the said operating condition, the height from the center of the pulley block at the top of the boom to the ground level is 71.3m, and the net height of the lifting is 其中3m为平衡梁下端绳长, 6m为平衡梁上端绳长, 6.5m为就位基础框架高度。Where 3m is the length of lower end rope of spreader

10、, 6m is that of upper end rope and 6.5m is height of framework of positioning foundation.可见吊装的净高完全能满足吊装要求。According to the above calculation, the net height of the lifting completely satisfies the lifting requirement.4.2 溜尾吊车吊装工况的选用Selection of the Operating Condition of the Tailing Crane参见图2，溜尾吊车的提

11、升力F为：Refer to sketch 2, the lifting force of tailing crane F is calculated as follows:经计算设备重心在5.2m处，The center of gravity of equipment is calculated at 5.2m. F= G+3=41+3=44t式中G为起吊时溜尾吊车承受PRIMARY PRODUCT EXCHANGER（E3102）的金属重量与保温材料的重量之和，吊钩及索具的重量为3t，因此选250t履带吊的工况为：起重臂长51.8m，作业半径12m。在此工况下，吊车的额定起重量为72.5t，

12、吊车的起重负荷率为=61%，其起重能力完全能满足溜尾吊装的要求。Where G is the sum of weight of metal and insulation materials borne on tailing crane. The weight of hook and riggings is 3t. Given the above, the operating condition of the 250t crawler crane is determined as: boom length 51.8m, operating radius less than 12m. Under

13、the said operating condition, the rated lifting capacity of the crane is 72.5t, the lifting load rate of crane=61%,which fully meets the tailing requirement. 5吊索具的选用Selection of slings and rigging5.1平衡梁Spreader为了使PRIMARY PRODUCT EXCHANGER（E3102）在吊装过程中从水平状态能够顺利地转到垂直状态，需要使用平衡梁，平衡梁为我方自行制造，详见图3. In orde

14、r to make PRIMARY PRODUCT EXCHANGER（E3102）be lifted smoothly to a vertical position from a horizontal position during the lifting operation, a spreader manufactured by us is to be used.

15、设备制造图。索具的受力计算如下：Tailing plate lifting lug and main lifting lug, supplied together with equipment, are manufactured by equipment vender. See the equipment manufacture drawings. The sling bearing force is calculated as follows:因此选用6个55t的卸扣，配合2对60.5mm钢丝绳扣（规格637+1（麻芯），=170kg/mm2，破断拉力为Pb=190t）作主吊索具，钢丝绳扣的

16、长度为12m，对折后打两双使用，折减系数按0.75计,该钢丝绳扣的安全系数n为：According to the above calculation, six 55t shackles are to be used matched by two pairs of 60.5mm wire ropes ( size 637+1 (hemp core), =170kg/mm2， break tensile force Pb=190t) as main slings and rigging. The length of wire rope is 12m, which will be used afte

17、r bent double. Discounting coefficient is 0.75. Then the safety parameter of this wire rope is calculated as follows:5.3溜尾吊耳及溜尾索具 Lifting lugs and slings for Tailing 溜尾的吊点选择在设备溜尾吊耳上，溜尾吊耳的结构及有关计算见设备制造图。The lifting point for tailing is set at the tailing lifting lugs of equipment, the structure of it

18、and relevant calculations see equipment manufacturing drawings.选用2个25t的卸扣，配合1对43mm钢丝绳扣（规格637+1（麻芯），=170kg/mm2, 破断拉力为Pb=97t）作溜尾吊索具，钢丝绳扣的长度为16m，对折后打两双使用，折减系数按0.75计,溜尾索具计算详见下列计算公式。Two 25t shackles are to be used matched by one pair of 43mm wire ropes (size 637+1（hemp core），=170kg/mm2, break tensile for

19、ce Pb=97t) as slings and rigging used for tailing. The length of wire rope is 16m, which will be used after bent double. Discounting parameter is calculated as per 0.75. Details of calculation for tailing slings, See the following formula:该钢丝绳扣的安全系为：Then the safety parameter of this wire rope is cal

20、culated as follows:66吊车对地面的压力核算Calculation of Pressure of Crane to the Ground61主吊车的履带对地面的压力Pressure of crawler of main crane to groundLR1400型履带吊在上述工况时的车身总重量为328t，吊装的负荷为82t，因此主吊车LR1400型履带吊对地面的压力G=328+82=410t；吊车履带的接地面积F=22.4m2，因此主吊车对地面的压强P为: Under the above working operation, the total weight of LR140

21、0 crawler crane is 328t and lifting load is 82t. So the pressure of main crane to ground G=328+82=410t and bottom area of crawler to the ground F=22.4m2. Then strength P of main crane to ground is calculated as follows:62 溜尾吊车的履带对地面的压力Pressure of crawler of tailing crane to ground250t履带吊的车身总重量为180t，

22、吊装的负荷为44t，因此溜尾吊车对地面的压力G=180+44=224t；吊车履带的接地面积F=17.2m2，因此溜尾吊车对地面的压强P为: Under the above working operation, the total weight of 250t crawler crane is 180t and lifting load is 44t. So the pressure of tailing crane to ground G=180+44=224t, and bottom area of crawler to the ground F=17.2m2. Then strength

23、P of tailing crane to ground is calculated as follows:为了保证吊装的安全，要求地面的地耐力大于20t/m2。For the sake of safety, the ground bearing capacity should be more than 20t/m2 7PRIMARY PRODUCT EXCHANGER（E3102）的吊装步骤：The Erection Sequence of PRIMARY PRODUCT EXCHANGER（E3102）PRIMARY PRODUCT EXCHANGER（E3102）吊装的主要步骤为：The
