摘要:: 本文对本刊第12卷第3期登载的“吊车的最佳工作位置”-文提出了不同的观点,并重新探讨了吊车的最佳工作位置。文中提出了三种不同情况下吊车的最佳工作位置并对其中两种作了详细的推导与论证。这两种最佳位置是:1.在保证吊装所需几何尺寸的前提下,使吊车具有最大吊装能力的位置;2.在保证吊车吊装能力的前提下,使吊车具有最大的有效工作幅度的位置。最后举例说明了最佳位置的确定方法。
Different points of view about“optimum working position of crane”published in Vol.12, No.3of this fissure are raised in this article.The optimum working positions of crane under 3 different conditions are reviewed. Two of whcth are deduced and argumented comprehcsively, i.e 1,Under the prerequisite of assuring the geometry size required by the crane, the position of crane can make the crag have the maximum lifting capacity.2. Under the prerequisite of assuring the lifting capacity of crane,the position of crane can make the crane have the maximum available working range .Finally methods for determining the optimum' position are described with examples.
