    限位器種類

    塔式起重機必須具備起重量限製器、力矩限製器

、高度限製器、行程限製器、幅度限位器等。

    （1）起重量限製器：也稱超載限位器、shiyizhongnengshiqizhongjibuzhichaofuheyunxingdebaoxianzhuangzhi，dangdiaozhongchaoguoedingqizhongliangshi，tanengzidongdiqieduantishengjigoudedianyuantingchehuofachujingbao。qizhongxianzhiqiyoujixieshihedianzishiliangzhong。

    （3）高度限製器：也稱吊鉤高度限位器．一般都裝在起重臂的頭部
，當吊鉤滑升到極限位置，便托起杠杆。壓下限位開關，切斷電路停車

，再合閘時，吊鉤隻能下降。
