These locking mechanisms can be manual, where the operator physically locks and unlocks the safety bar, or automatic, where the safety bar locks into place once lowered.

Regular maintenance and inspections are also crucial to ensure the safety bars are functioning correctly and securely. **

Overall, these structures work together to securely hold the heart in place and protect it from excessive movement. **
