What is the difference between a metallurgical bridge crane and an ordinary bridge crane?

The earliest difference between metallurgical bridge cranes and ordinary bridge cranes is very small. Due to frequent safety accidents, some mandatory requirements for metallurgical cranes are proposed: for example, steel core wire ropes, steel wire rope safety factor is higher than ordinary one, high temperature design, double Brake double limit, hoisting mechanism with ultra-high speed protection, more than 100t need to add safety monitoring system, safety brake system, crane with thermal protection device.
