摘　　要：检索式起重机力矩限制器的控制目标不局限于若干条特定的幅度——起重量曲线,而是整个起重量曲面。因而可以做到在起重机臂架任何工作位置上既不降低其起吊能力,又确保其安全工作。检索式力矩限制器可以不用微机处理,便于在各类中小吨位轮式起重机上推广应用。文中简述了检索式力矩限制器的设计思想和电路工作原理。The control target of the present indexingtipping moment limiter is not confined in acertain number of load characteristic curves,but the total load-reach area instead is consi-dered, so that the crane will operate in anyposition inside the said area without loweringits hoisting capacity and its safety operationcan be maintained. This type of limiter canavoid the use of micro processor making it p-ractical for medium and small capacity applications. The design concept and electric principlediagram of this moment limiter are briefly des-cribed in this paper.
