不同额定起重量吊车同点双抬吊装法

The method of double-crane hoisting lifting installing large equipment by using different hoisting weight cranes

本文以加氢精制反应器的成功吊装为例，介绍利用几台不同起重量的吊车吊装大型设备的方法。采用专门设计加工的平衡梁，实现预先设定行重的分配，解决了不同起重量的吊车同点抬吊受力不均衡的施工问题，在保证安全的前提下，可以最大限度地发挥每台吊车的起重能力。

This paper takes an example which is to hoist and install hydrorefining reactor. It introduces the method of hoisting and installing large equipment by using several different specified hoisting weight cranes. To adopt a balance beam of special design and manufacture to achieve appointing the weight beforhand, to solve the problem of force unbalance during several different specified hoisting weight craned. As a result every cranes could be hoisted the full weight under the prerequisite of safety.
