摘要:
In the embodiments described herein, the scale assembly automatically determines if an accessory, such as a sling, is properly connected to a sling bar of the person lifting device and, if the accessory is not properly connected, the scale assembly provides a user with a visual and/or audible warning and, in some embodiments, may lock-out the actuation controls of the person lifting device to prevent the person lifting device from being used.
