Product description of crossing limit switch :
A limit switch is a critical component of overhead crane safety.
Limit switches are electromechanical devices that regulate
everything from household appliances to industrial machinery. And
for an overhead crane, they provide solid, established points of
reference for maintaining efficiency, reliability and safety
Limit switches have practically limitless applications in
regulating crane operation to prevent potential incidents. For
instance, when ropes come out of groove or in preventing two
trolleys from impacting on the same bridge structure.
