  "abstract": "This disclosure describes a plate handling tool designed to securely grip and lift plates with varying thicknesses and weights. The arrangement employs a mechanical wedge action to generate a gripping force that is proportional to the downward load exerted by the plate itself, thereby addressing the problem of excessive clamping force for thin, light plates and insufficient force for thick, heavy plates. This proportionality is achieved through specific wedge geometry, ensuring stable handling across a defined operating range without requiring active force adjustments. The tool provides a controlled interaction with the plate edges, minimizing surface marking while preventing slippage.",
