2020年11月10日 — PDF | There have been accounts of repeated failure of crane hooks at the coil yard of a Hot Strip Mill which pose a serious threat to safety in the
chains, cranes, failed shafts, hooks, lifting equipment, wire rope lifting equipment used in steel mills and similar industrial applications, but the problems encountered Metallurgical examination of several wires revealed a uniform cold-drawn The acceptable load limit of the chain was approximately 13,600 kg (15 ton).
The hook was part of the auxiliary hoist of an electric overhead crane used in a foundry. It was of the shank type and the rated safe working load was 15 tons.
