The length of main beam is 54.9m, working radius 1216m. The erection radius is dependent on the weight of plate beam.5.2吊装钢丝绳的选用：The application of slings:根据大板梁的规格，尺寸重量，安装高度，吊点位置，确定钢丝绳的直径，钢丝绳的长度。 大板梁64606-2-1- 0，选用28钢丝绳，长度15。4个大板梁使用同一对钢丝绳吊装。5.3吊点选择及绑扎方法： Confirm the diameter and length of sling in accordance with specification, size, weight, height, and location of plate beam. Apply 15m of 28cm sling to erect plate beam(DWG No 64606-2-1-0). The four plate beam will be erected with the same sling.选择吊点要根据大板梁的重量，重心，外形尺寸，及空间的安装位置，进行吊点选择，大板梁的吊点选择，首先找出大板梁的中心点，左右两侧1.52.5即大板梁吊点。捆绑方法，一对钢丝绳两头打空圈兜吊，或者使用U型卡环捆绑，两点起吊均可，不管采用何种捆绑方法，都必须保证设备不变形。绑绳处有棱角，要用软物或半圆管垫好。 Choose a erecting point in accordance with the weight, center of gravity, shape, size and installation location. Firstly find out the center of plate beam, 1.52.5 from the two ends is the erecting point of plate beam. Fastening method: a pair of sling fixed with U clamp and erect material simultaneously at two ends. No matter what kind of method is applied, it must guarantee that there is no distortion of the plate beam. If there is any edges and corners at the fastened location, use some soft material or semi-circular pipe to underlay. 5.4 依次吊装提前预放在钢架内的64606-2-1-0，64606-2-2-0,大板梁。首先将大板梁吊起离地面大约200，停止起吊，然后快速落钩紧急停止，观看制动刹车是否灵活有效。并在离地面200之处停留35分钟，确认没问题后开始起吊。起吊时应在大板梁两端绑一麻绳作为遛绳，防止大板梁在起吊过程中，碰撞立柱或横梁。大板梁就位后应检查大板梁的中心线，水平标高，检测合格后方可落钩。按同一步骤，方法，吊装-2大板梁。Erect plate beam (DWG No.64606-2-1-0 & 64606-2-2-0) which is loaded under boiler steel structure respectively. Firstly lift up plate beam for 200cm, hold on, then low down the hook and stop to see the brake is agility or not. Hold on for 3-5 mins at 200cm up of ground, and start to erect after confirmation. Tie control rope at each end of plate beam so as to avoid hitting column of horizontal beam during erection. Examine the center line and elevation of plate beam, and loose the hook after all parameters are qualified. Then erect the other plate beam with the same method.5.5在BM-2大板梁就位后，须将BM-1和BM-2大板梁之间连接横梁吊装完毕后，再吊装64606-2-3-0大板梁。连接BM-2BM-3之间横梁，依次顺序吊装至BM-4。After the positioning of BM-2 plate beam, connect all the horizontal beams between BM-1 & BM-2. Then erect plate beam of 64606-2-3-0. Connect horizontal beams between BM-2 & BM-3, until BM-4.5.6履带吊吊装大板梁站位示意图Sketch map for plate beam positioning with crawler crane6 组织机构及人力资源Organization and Manpower现场经理site manager陈富安 ChenFuan 负责人Boiler chief 王飞 Wang Fei吊装负责人ifting engineer郭继民Guo Jimin钢结构负责人S/S engineer曹军平Cao junping焊接负责人Welding engineer邢建钢Xing Jiangang材料负责人Materical engineer 王滕Wang Teng起重工4人 rigger 4当地4人Local worker 4钢结构安装工16人Erection worker 16,当地10人local worker 10焊工6人 welder 6当地4人 local worker 4材料工2人helper 2当地2人local worker 2 inspection record of sole platerefers to attachment 37.工具和材料Tools and equipments No.NameType & specification QTY1Crawler crane 180T1 set2Mobile crane 35T1 set3Sling 28 L=15m1 pair4U clamp 10T4 pc5Hemp rope21100m6Chain clock 5T2 pc7Chain clock 3T2 pc8Sling 17 L=5m4 pc8 安全环境 Safety and Environment 8.1吊装前需进行安全和技术交底，施工人员必须做到四个明确，即吊装任务明确，施工方法明确，吊物的重量及吊装过程明确，安全注意事项明确Before erection, perform teach-know-how about safety and technique, and construction staff must be clear about erection work and method, be clear about the weight of erected material and erection process, and be clear with the safety cautions.8.2保持良好的施工环境，材料，设备的堆放要符合施工及消防的要求，摆放，整齐有序，不妨碍通行。Keep a good environment for construction, and the storage of material and equipment should meet the fire-fighting requirement, e.g. put in order and not block the access. 8.3遵守各项规章制度，提倡文明施工，杜绝野蛮施工。Follow the regulations of constructions, avoid uncivilized construction.8.4起吊作业区域，严禁非施工人员通过或逗留。The person beyond construction staff is forbidde
