安全滑触线的使用为车间带来了安全，但也有缺点，桥式起重机在使用中易断电，有时在输电导管内产生火花，严重时滑触线某放炮，造成集电器更换过于频繁，影响生产。
the use of safety sliding contact line as the workshop brought security, but there are also disadvantages, easy off bridge crane in use, sometimes sparks in the transmission conduit, serious when sliding contact line of a shooting , causing the collector to replace the too frequent, affecting production.
为此，进行了如下改进：
therefore, for the following improvement:
(1)加深。加固集电器中的弹簧座，保证电刷的恢复弹簧在工作中不易串位；
(1) deepen. strengthening the spring seat set in electric appliance, ensure that the brush recovery spring in the work is not easy on;
(2)增大集电器电刷倒角，并打磨光滑；
(2) increase the collector brush chamfered, and polished;
(3)两段安全滑触线连接处连接块要有倒角，保证集电器平滑过渡。同时，为保证安全滑触线的正常使用，行车工的规范操作、维修工的定期保养、定期检查也*。
(3) the two security sliding touch line connected block to have chamfer, ensure a smooth transition in electrical appliance. at the same time, in order to ensure the safety of the normal use of the sliding contact line, operation and maintenance workers driving workers regulate the periodic maintenance, regular inspection is necessary.
(4)增加集电器两相对电刷间弹簧强度、弹性，保证弹簧恢复自如；
(4) increase the collector two relative brush spring strength, elasticity, ensure the spring recovery free;
