对于大型设备的吊装施工，可采用吊装平衡梁的方法。平衡梁横截面的合理选择是首要的因素，在某种程度上决定了吊装的成败。在拥有相等截面积的条件下，如何设计和利用具有最大刚度的平衡梁是本文探讨的主题。
For the hoisting of large-scale equipment, the method of hoisting the balance beam can be used. The rational choice of the cross-section of the balance beam is the primary factor, which determines the success or failure of the hoisting to some extent. How to design and use the balance beam with the maximum stiffness under the condition of having an equal sectional area is the subject of this article.
