Limit switch is an important part of the safety of Overhead Crane. The limit switch is electromechanical equipment, which can adjust all the equipment from household appliances to industrial machinery. For bridge cranes, they provide a solid reference basis for maintenance efficiency, reliability and safety standards.
The limit switch has almost unlimited application in regulating the operation of the crane to prevent potential accidents. For example, when the rope comes out of the groove or prevents two trolleys from hitting the same bridge structure.

Once you find a car is out of fire, don't panic, stop and turn off immediately, turn off the power, turn off the tank switch and blinds, and leave the car immediately. If the door cannot be opened, it can be separated from the windshield.

Car maintenance, aging rubber cracks inside the vehicle and plastic parts will easily lead to circuit short circuit; vehicle oil will evaporate and cause mechanical wear during driving, and various problems will occur in the circuit; or privately installed in-vehicle electrical appliances will have poor bonding and large resistance. Produce high temperatures ... These reasons are easy to cause auto-ignition.
