  "abstract": "This disclosure describes a dock leveller lip control system designed to maintain continuous contact between the leveller lip and a trailer bed during loading or unloading operations. The system addresses the problem of trailer suspension settling, which causes the trailer bed height to decrease as its load increases, potentially leading to a loss of bearing for the leveller lip. It incorporates mechanisms for detecting lip contact loss and features an interlock with a vehicle restraint system to ensure operational safety and efficiency. The control system permits a designated settling range while actively managing lip position to ensure proper load transfer.",
