桥式、门式起重机起升卷筒直径的计算

Calculation of Hoisting Drum Diameter for Bridge Crane and Gantry Crane

介绍了桥式、门式类型起重机起升卷筒作多层卷绕时卷筒直径的优化计算方法，使用此法可避免采用过大的卷筒，有效地减轻起重机的重量和降低造价。同时，提供了多组图表，以便在进行方案设计时尽快确定卷筒的最佳尺寸。

This paper introduces an optimum calculating method of hoisting drum diameter for bridge and gantry cranes. When the rope windes on drum multiple layers, so can be avoided t0 adopt a very big drum, reduced the weight of crane efficiently. as well as cut the price. At the same time, this paper provides same figures to determine the best size of drum quickly, when a layout is being planned.
