摘要
用卷筒轴向蜗轮式限制器代替电动双梁桥式起重机中原有的重锤式限制器，可避免因连杆断裂造成的限位失灵，保证起重机安全运行。与改进前相比，每年可避免轧机机列停机损失５０ 多万元。
The counterweight limiter used in electric drive double beam bridge crane is replaced by barrel axial turbine type limiter,it can avoid limiting position uncontrol caused by fracture of link lever,can ensure safe operation of crane Compared with old device,it can increase profit of 0 5 million yuan every year
