  • Patent number: 9527699
    Abstract: A control system for a lifting device and a lifting device comprising the same are disclosed. The control system includes a control unit comprising a processor with a memory communicatively coupled to the processor and having computer readable and executable instructions. A battery is electrically coupled to the control unit in addition to at least one indicator. The processor executes the computer readable and executable instructions to: determine an operating characteristic of the lifting device and an operating time of the lifting device as the lifting device is actuated; determine an accumulated load-time parameter for the lifting device based on the operating characteristic and the operating time; store the accumulated load-time parameter in the memory of the lift control system; compare the accumulated load-time parameter to a service constant; and provide an indication the indicator that a lift structural component requires service based on the comparison.

  • Publication number: 20150107020
    Abstract: Disclosed is a patient lift system having a sling bar with an inductively charged integrated scale. The lift system comprises a lift apparatus, a lift strap connected at a first end to the lift apparatus, a sling bar connected to a second free hanging end of the lift strap, the sling bar having a scale with a tension load cell integrally disposed therein for measuring forces applied thereto and a power source electrically connected to the scale to provide power to the scale and load cell. An accelerometer is disposed within the sling bar to determine a tilt angle of a lift axis of the load cell relative to a vertical direction of gravitational force. Programming stored in a processor of the integrated scale calculates an accurate weight of an active load suspended from the sling bar, based on the determined tilt angle and the measured force on the load cell.
