Therefore, in the packaging process, the steel coil is lifted by the crane for 2-3 times, so that the use frequency of the crane is high. Because the steel coil needs to be manually pushed and supported in the hoisting process, the solution of an unmanned overhead traveling crane (automatic overhead traveling crane) cannot be adopted for hoisting the steel coil in a factory.
The operation of the crown block belongs to high-risk work species, the operation rate is too high, and the potential safety hazard is more.

The steel coil is lifted by the overhead travelling crane and is difficult to lightly take and place, so that the impact between the steel coil and the ground saddle can be caused, the impact can cause the damage of the steel coil, and the reduction of the steel coil yield is caused. In the manual packaging process, due to the swing and instability of the crown block, the packaging material is better and difficult to wrap, and in the subsequent transportation process, the conditions of coil loosening and packaging material damage are easily caused, so that a large amount of quality compensation is caused due to the packaging quality. According to the statistical result of a certain steel mill in China, the damage rate of the quality of a cold-rolled sheet and a package produced by 100 ten thousand tons per year reaches 3 percent, and the loss amount is 100 × 1000 (1000 yuan per ton of the lost money), 3 percent is 3000 ten thousand yuan per year.
