Precautions for Lifting Operation of Bridge Crane in Steelmaking Plant

Operating a high-temperature liquid bridge crane is a relatively dangerous job. In order to ensure safe production, the absolute safety of the equipment (bridge crane, ladle, sling) must first be ensured. If these two problems occur, for example, the wire rope of the bridge crane or The consequences of a broken sling are disastrous. If the ladle wears steel, the consequences are more serious. The second problem is the quality of personnel. Major mistakes made by crane workers or ground commanders can also cause serious consequences. These questions are the most basic requirements. In addition to these, there are some other considerations:

1.  The bridge crane route should be opened for the place where the ladle on the ground passes. That is to say, the ground should have a flat and dry passage that is enough to pass the ladle and there is no debris. The purpose of leveling is to ensure that the ladle is accidentally dropped. It will not be dumped, and the molten steel will not spill out, reducing the consequences of accidents. The purpose of drying is to prevent molten steel from exploding once it is spilled.
2.  Ground personnel are not allowed to move or stay or rest in the crane route area, and personnel cannot compete with the crane to reduce the probability of accidents.
3.  There are no or as few rest rooms and meeting rooms as possible near the crane route to prevent the occurrence of serious accidents that cause deaths and injuries due to the falling of the ladle.
4.  The height of the ladle from the ground should be controlled when the crane is hoisting the heavy package, preferably not more than one meter. That's basically it.

1.  If the cab is in the car, getting on and off the car is a more important link. Pay attention to the surrounding environment and the condition of the cab door, and exchange information with the handover personnel. If it is a remote control crane, check the equipment before taking over the shift (the remote control should still be in the hands of the driver at this time, and you must pay attention to information communication if you want to get on the car for inspection).
2.  In addition, it depends on what lifting work your bridge crane is mainly responsible for. If it is lifting liquid metal, be careful, especially the lifting operations of the steelmaking furnace and subsequent processes, such as the sky responsible for loading the converter. The truck must be careful of splashing in the converter (whether it is molten iron or scrap steel, the risk factor is very high. There have been many accidents in various steel mills, and the driver of the crane hangs on the spot). If the molten steel is lifted Pay attention to the ladle, because the ladle overturns and splashes are more likely to occur.
3.  Others are relatively safe, mainly for information communication and safety confirmation with the personnel cooperating with the operation.

Finally, we must carefully study the safety regulations and documents in the factory. Strictly follow the operating procedures .
