The main performance of BCD hoist is reflected in the word "explosion-proof", and the most important part in the following detailed explosion-proof hoist is the "electric control system".

　　The explosion-proof hoist electric control system consists of a hoist box, a button control box, and a cut-off limiter. The explosion-proof electrical device enclosure is tightly sealed to meet the corresponding explosion-proof level requirements, and its internal functions are basically the same as those of ordinary hoist electrical devices.

　　The electrical components inside the explosion-proof hoist box are all made of high-quality and reliable Siemens low-voltage electrical components, reducing the number of times the explosion-proof box is opened due to electrical faults. In addition to electrical interlocks between contactors in the opposite direction inside the control box, mechanical interlocks are also installed in the button control room to avoid short circuits caused by operational errors. The button box is equipped with a rotary reset emergency stop switch, which is convenient for quickly stopping the motor in emergency situations. The control box buttons use internationally recognized arrow identification symbols and use an AC 36V safety control voltage.

　　The explosion-proof flameout limiter consists of a limiter control box and an external guide rod. The steel wire rope guide card on the drum pushes the guide rod and triggers the contact action inside the limiter control box to cut off the power supply of the lifting motor.
