通用龙门起重机和装卸桥的结构静刚度,是指移动载荷(额定起重量和小车自重)在主梁(或主桁架)跨中或悬臂端引起的垂直静挠度与跨度(或悬臂有效工作长度)的比值。 本文针对通用龙门起重机和装卸桥分析了小车在主梁上移动时产生最大坡度阻力时的位
The static stiffness of universal gantry cranes and handling bridges refers to the vertical static deflection and span (or effective working length of cantilever) caused by the moving load (rated lifting capacity and deadweight of the trolley) caused by the span of the main beam (or main truss) The ratio. In this paper, a general purpose gantry crane and the loading and unloading bridge analysis of the car when moving in the main beam when the maximum gradient resistance bit
