一、工程概况50万吨/年催化加氢压缩机厂房为双层单跨预制混凝土梁柱排架结构,构件数量吨位见吊装构件一览表,其中最大构件为Z-4、Z-5抗风柱,理论重量为19.284T,构件长度为17.73m,起吊高度为19.83m。此厂房属原厂房扩建,场地狭小、不利吊装、且吊装构件少,如用大吨位吊车显然会增加成本。因此我们通过精确计算用德国产28T履带吊车成功地完成了吊装任务,为单位节约了资金,创造了效益。
First, the project overview 500,000 tons / year catalytic hydrogenation compressor plant double-span single-beam precast concrete beam column rack structure, the number of components see the list of lifting components tonnage, of which the largest member of the Z-4, Z-5 wind column , Theoretical weight of 19.284T, component length of 17.73m, lifting height of 19.83m. This plant is an extension of the original plant, a small venue, unfavorable lifting, and lifting components, such as the use of large tonnage cranes will obviously increase costs. Therefore, we successfully completed the hoisting task with the German-made 28T crawler crane through precise calculation, saving funds for the unit and creating benefits.
