Claims17
A retractable sheave system for positioning a cable across an aircraft runway surface, comprising:
- a foundation comprising a cavity therein,
- a beam that functions as a sheave configured to be positioned within the cavity,
- a hinge associated with the beam;
- a lifting/lowering mechanism associated with the beam,
- wherein when the lifting/lowering mechanism configures the beam in a lowered position, the beam rests within the cavity and is flush with the aircraft runway surface, and wherein when the lifting/lowering mechanism configures the beam in a raised position, the beam hinges with respect to the hinge such that at least the forward portion of the elongated beam raises above the runway surface.
