による落板の危険性がある。As described above, when a steel sheet is conveyed by a lifting magnet, the magnet generally has a lifting capacity of 7 to 12 tons. However, steel plates (thick steel plates, etc.) are large in both width and length, and the flatness of each steel plate is different. If multiple steel plates are stacked due to bending deformation, wavy shape, etc. In addition, an air gap may occur between the steel plates, and the penetration of the magnet magnetic force may be hindered, and the attractive force of the magnet is weakened, so that it is difficult to lift and transport a large number of steel plates at once. In addition, in the case of lifting and transferring, there is a risk of dropping due to a change in speed at the time of hoisting and unwinding, a change in speed at the time of transfer, vibration caused by a seam of a crane running rail, or the like.

る。When a hacker holds a steel sheet and lifts and conveys it, it is possible to convey a large number of steel sheets at a time. Work to insert the floorboard into the
When steel sheets are stacked without inserting a floor plate, it requires a lot of work such as sorting work of large and small steel sheets to engage hackers, and the work efficiency is extremely low, and the conveyance capacity of the steel sheets is extremely low. There are issues such as the fact that it is decreasing. The present invention has been made to solve such a problem advantageously, and by using a lifting magnet for a steel sheet, a large amount of steel sheets can be quickly loaded and conveyed without much labor by loading a lifter device. It is an object of the present invention to provide a method and an apparatus for lifting and transporting a steel sheet.

According to the longest length of the steel plate, two or more lifters are serially suspended and mounted on the crane suspension beam at substantially equal intervals to form a steel plate lifting and conveying device. Then
When engaging the steel plate with the lifter device of the lifting and conveying device, the central part in the width direction of the steel plate is sucked and lifted by a lifting magnet, and then a pair of hackers of the lifter device are moved to and contact both ends in the width direction of the steel plate. ,
The hacker claws are engaged with both ends in the width direction of the steel sheet, and then the lifting magnet is demagnetized to release the adsorption. The crane lifts and lifts the lifter device (steel plate lifting and transferring device) to a predetermined position, and then lands. And slightly lift the steel plate, move the pair of hackers of the lifter device to the outside of both ends in the width direction of the steel plate, and remove the hacker claws from the steel plate. Next, the steel sheet lifting and conveying device is moved to the steel sheet storage place again.

能力等を大幅に向上することができるものである。When a large number (large number) of steel plates are lifted and conveyed, first, one end in the width direction of the steel plate is lifted by a lifting magnet, the other end is in a landing state, and the lifted one end is connected to one end of a lifter device. After engaging with the hacker claw, the other end in the width direction of the steel plate is lifted by a lifting magnet, and after engaging with the other hacker claw, lifted and conveyed. With this configuration, one end or the other end in the width direction of the steel plate is landed compared to the case where the entire steel plate is lifted and engaged with the hacker claw, and the lifting force by the lifting magnet can be lifted by about ２. Therefore, a large number (large number) of steel plates can be loaded on the lifter device (steel plate lifting and transferring device), and the transfer capacity can be greatly improved. That is, since a steel sheet having a suspended load equal to or greater than the specified capacity of the lifting magnet can be loaded into the lifter device by one-time handling, the transport capacity and the like can be greatly improved.
