A cable crossover/protector that comprises illumination as an integral part of its structure to warn of its presence. The crossover/protector may include an element to sense when current is being carried by the cables it is protecting to activate the illumination.
Claims28
A protective crossover unit for a utility line laying on a traveled surface, comprising
- a body member having a pair of opposed ramp portions constructed to form a protective bridge for the utility line, each of the ramp portions having inclined surfaces;
- and
- an electrically powered illumination element formed in the body member operating to indicate presence of the crossover unit when illuminated.
A crossover unit for overlaying at least portions of utility lines, including electrical lines, water lines, and gas lines, comprising
- a body member having at least one channel formed to receive a utility line, the body member having a pair of opposed ramp portions adjacent the channel, each of the ramp porions having inclined surfaces;
- a cover element adapted to overlay the channel;
- an electrical illumination element formed in the body member operating to indicate presence of the cable protector when illuminated.
A protective crossover unit for a utility line laying on a traveled surface, comprising
- a body member having a pair of opposed ramp portions constructed to form a protective bridge for the utility line, each of the ramp portions having inclined surfaces;
- an illumination element formed in the body member operating to indicate presence of the crossover unit when illuminated;
- and
- a switch having a first switch position for applying electrical power to the illumination element and a second switch position for withholding electrical power from the crossover unit.
A protective crossover unit for a power line laying on a traveled surface, comprising
- a body member having a pair of opposed ramp portions constructed to form a protective bridge for the utility line, each of the ramp portions having inclined surfaces;
- an illumination element formed in the body member operating to indicate presence of the crossover unit when illuminated;
- and
- a sense element situated to sense the presence of electrical current in the power line to activate the illumination element.
A protective crossover unit for a power line laying on a traveled surface, comprising
- a body member having a pair of opposed ramp portions constructed to form a protective bridge for the utility line, each of the ramp portions having inclined surfaces;
- a plurality of bi-colored LEDs mounted in the body member and operating to indicate presence of the crossover unit when illuminated.
A protective crossover unit for a utility line laying on a traveled surface, comprising
- a body member having a pair of opposed ramp portions constructed to form a protective bridge for the utility line, each of the ramp portions having inclined surfaces;
- an illumination element mounted in the body member operating to indicate presence of the crossover unit when illuminated;
- and
- an electronic circuit contained in the body member for selectively communicating electrical power to the illumination element for producing illumination therefrom.
