Development of Rotary Special Lifting Device for Scrap Trough

In order to add steel scrap into a convertor by turning the scrap trough at make the angle of 90 degrees, the rotary special lifting device with four lifting points for mandatory balance for the scrap trough was developed. In the operation, the scrap trough was lifted and lowered by controlling main hoisting mechanism of the crane. By turning the start button for controlling the lifting device to rotate forwards or backwards, the scrap trough could be placed at any angle in the range of 360 degrees in the horizontal direction for adding steel scrap into the convertor.
