Damage types of metallurgical cranes

Crane operation characteristics

1. metallurgical cranes are used for specific service targets, and special fetching equipment and operation organizations are often planned according to the crane's service targets and technological process.

2. In order to increase the production rate of cranes, the operating speed and acceleration are often much higher than that of general-purpose bridge cranes. At the same time, the starting and braking of the various organizations of the crane are very frequent, especially the working organization and the rotating organization are often in the starting and braking conditions. Therefore, the organization of the selection of motor capacity must meet the necessary acceleration requirements.

3. The working environment has a high temperature and the lifting of the workpiece is large. When selecting the electrical control equipment of the motor, the insulation level of the components is required to be higher, and the scale of the starting current change is large.

4. The iron (steel) lifted by the crane has high temperature, different shapes of workpieces, large weight, wide handling scale, and large lifting drop. Therefore, the crane’s safety measures and the regular inspection and inspection requirements of safety maintenance equipment are particularly strict.
