[0002] Steel plates are flat steel products cast from molten steel and pressed after cooling. They are flat and rectangular, and can be directly rolled or cut from wide steel strips. Steel plates are classified by thickness into thin steel plates < 4 mm (the thinnest is 0.2 mm), medium-thick steel plates 4 - 60 mm, and extra-thick steel plates 60 - 115 mm. Steel plates are classified by rolling into hot-rolled and cold-rolled.
[0003] However, in actual applications, when most existing long steel plates are hoisted, binding ropes are used to tie the two ends of the long steel plate and then the binding ropes are hung on the lifting beam, and the hoisting of the long steel plate is completed by the movement of the lifting beam.
