The invention belongs to the technical field of crane control, and particularly relates to a crane performance extension method and system and a crane. The method comprises the following steps: screening out a query telescopic combination from given telescopic combinations of the crane based on a current telescopic combination; based on the matching relationship between the current scaling combination and the current working amplitude, obtaining the query working amplitude of the query scaling combination; based on query of the working amplitude, query of the total boom length of the telescopic combination and query of the performance table of the telescopic combination, the rated hoisting weight of the crane under the current telescopic combination, the current working amplitude and the current multiplying power is obtained; and obtaining the maximum working amplitude of the current telescopic combination according to the total arm length of the current telescopic combination based on the matching relationship between the maximum working amplitude of the query telescopic combination and the total arm length of the query telescopic combination. According to the invention, the problem that the crane with the single-cylinder bolt telescopic arm cannot perform hoisting operation under the safety protection of a force limiter under the condition of no telescopic combination with given performance is solved.

    本发明属于起重机控制技术领域,具体涉及一种起重机性能扩展方法、系统及起重机。该方法包括,基于当前伸缩组合从起重机的给定伸缩组合中筛选出查询伸缩组合;基于当前伸缩组合与当前工作幅度的匹配关系,获取查询伸缩组合的查询工作幅度;基于查询工作幅度、查询伸缩组合的总臂长、查询伸缩组合的性能表,获取起重机在当前伸缩组合、当前工作幅度、当前倍率下的额定吊重量;基于查询伸缩组合的最大工作幅度与查询伸缩组合的总臂长的匹配关系,根据当前伸缩组合的总臂长获取当前伸缩组合的最大工作幅度。本发明解决了单缸插销伸缩臂的起重机在无给定性能的伸缩组合下,无法在力限器安全保护下吊装作业的问题。
