US Patent 9409712 Apparatus for grasping, lifting and moving a large panel

A panel gripping and lifting device (100) having a clamping assembly (105) having a handle assembly (162) rotatably interrelated with a spaced apart opposing jaw assembly (107) by a cam assembly (149). Jaws of the opposing jaw assembly (107) have a planar jaw inner surface (116); when the spacing between the jaws is increased, the planar jaws are fitted on either side of a panel; when the spacing between the jaws is lessened the planar jaws contact surfaces of the panel exerting a gripping force against the panel. When gripping forces are exerted against the panel the handle assembly (162) enables the lifting and moving of the panel such as seated multipane window (220) window frame (200) having an outwardly extending nail fin (210) or a sheet metal panel.
