Securing Machining Unit to Prevent it from Falling

The Y-axis drive is not self-locking. Persons in the traversing range of the machining unit may be seriously injured if the drive motor holding break fails. In the event of a collision, the Y-axis can drop down further even if it is in the lower end position of the traversing range. The machining unit must be supported before work is carried out in the danger zone.
