Abstract: The present invention is a crane operating system and method which monitors the crane moment load in order to keep the crane within the safe operating envelope. In determining the current crane moment load the system considers boom raising cylinder pressure, boom angle, chassis incline, as well as hydraulic pressure.

Abstract: A fishing lure to simulate a dragonfly in a hovering orientation above a body of water is presented to effect luring of various game fish. The dragonfly member is defined by an elongate body mounting a plurality of cluster hooks at spaced intervals along the bottom surface thereof. The dragonfly structure may be mounted in a suspended orientation relative to the body of water utilizing a flotation device, or alternatively utilizing a drive motor and associated receiver and transmitter to effect hovering orientation of the lure. Further, the lure may be formed with a concave nose and a container within the body to effect selective tippage and repositioning of the body during its displacement through the body of water.
