Locking mechanism with multiple stage locking verification

A human lift system, comprising:

• a workspace having a local controller for maneuvering the workspace;
• an anchor point disposed in the workspace;
• a locking mechanism including:
• a receiver base having a plurality of locking components configured to securely engage a device, at least one of the plurality of locking components including an indicator configured to indicate that a respective locking mechanism is secured with the device and a pair of locking tabs configured to pivot about a respective pin operatively coupled to the receiver base;
• a linking member coupled to the receiver base coupled to the anchor point;
• and
• a signal wire coupled to the receiver base and configured to communicate a signal to the local controller that corresponds to the indicator.

A method for providing safety to a worker, the method comprising:

• in a human lift device, inserting a personal safety harness device into locking mechanism having a linking member attached to an anchor point of the human lift device and having a receiver base with a plurality of locking components including a pair of locking tabs configured to pivot about a respective pin operatively coupled to the receiver base,
• sensing whether or not a plurality of indicator switches indicate that the personal safety harness device is properly engaged with the locking mechanism through the linking member;
• and
• disengaging a local controller if any one indicator switch in the locking mechanism indicates that the personal safety harness device is improperly engaged with the locking mechanism.
