Under traditional hoisting methods, there are difficulties in controlling the swing and uneven force during the hoisting of heavy equipment such as the zero section of the wide plate casting machine and the crystallizer. Furthermore, the existing improvement schemes increase the risk of working at height.
A dual-mode anti-sway rigid hoisting system for wide plate casting machine zero section and crystallizer is adopted, including a hoisting body composed of a rigid frame and a main crossbeam. The longitudinal beam and detachable hoisting part are connected by submerged arc welding. A double guide chain structure and a rotatable shaft hanging end are used, combined with wire rope sleeves and hooks to achieve stable hoisting.
It achieves swing control of less than 5° during the hoisting of heavy equipment, eliminates lateral force, and shortens the hoisting mode switching time to less than 3 minutes, thus improving operational safety and efficiency.
