Definitions
- the present invention relates to a lifting beam for handling a shaft.
- the invention further relates to a manufacturing cell, a manufacturing environment and a method for handling a shaft.
- Endless materials such as foils, tubular foils, paper or the like are often wound as material rolls onto winding shafts or unwound from winding shafts in the context of production, finishing and/or further processing.
- Such winding shafts can weigh several hundred kilos or several tons together with the recorded roll of material.
- the winding shafts with the rolls of material are usually handled using a load traverse.
- the setting down or lifting of the winding shaft usually requires manual intervention by a machine operator in order, for example, to remove rope loops or load hooks of the load beam from the shaft or to attach them to the shaft.
- Such manual interventions are time-consuming, error-prone and, last but not least, represent an increased risk of injury for the machine operator, since he is working in the immediate vicinity of large loads.

- the locking bar 72 falls back into its closed position in a spring-loaded, elastic manner, closing the groove exit 76 or the groove outlet 76 of the groove 58 .
- the above aspects apply equally to the guide rail 50 arranged opposite.
