The invention provides a variable-amplitude moving method for a super-lift counterweight, a variable-amplitude moving system and a crane, and relates to the technical field of cranes. The variable-amplitude moving method comprises the following steps that firstly, whether the initial ground clearance of the super-lift counterweight is within a ground clearance reference range or not is detected, and if the initial ground clearance is detected to exceed the ground clearance reference range, a super-lift counterweight lifting oil cylinder is controlled to move the super-lift counterweight to a position where the ground clearance is consistent with the set ground clearance; then, based on the size relation between the initial super-lift radius and the target super-lift radius, a super-lift counterweight variable-amplitude oil cylinder is controlled to conduct variable-amplitude movement on the super-lift counterweight to a position where the super-lift radius is consistent with the targetsuper-lift radius, and meanwhile, a super-lift counterweight lifting oil cylinder is controlled to extend or retract, so that the super-lift counterweight is always kept at the set ground clearance in the variable-amplitude moving process. Through the method, an operator does not need to switch back and forth between a lifting action and a variable-amplitude action, and the operation is simple.
本申请提供了一种超起配重的变幅移动方法、变幅移动系统及起重机,涉及起重机技术领域,其中,变幅移动方法先检测超起配重的初始离地高度是否在离地高度参考范围内,若检测到初始离地高度超出离地高度参考范围,则控制超起配重提升油缸将超起配重移动到离地高度与设定离地高度一致的位置;然后基于初始超起半径与目标超起半径之间的大小关系,控制超起配重变幅油缸将超起配重向超起半径与目标超起半径一致的位置进行变幅移动,并同时控制超起配重提升油缸伸长或收缩,使超起配重在变幅移动过程中始终保持在设定离地高度;这样一来,操作员不需要在提升动作和变幅动作之间来回切换,操作简单。
