Abstract: A disconnect system for modular cable protectors includes tool engagement features to facilitate disassembly of the side ramps from the center sections of the cable protectors using a hand tool. The tool is used to removably engage these tool engagement features to enable the user to exert an upward force to disengage the edge connectors and end connectors on the side ramps and center section of each cable protector. For example, the tool engagement features can be openings (e.g., slots or recesses) in the top surface of the side ramp with undercuts adjacent to the lower ends of the openings. A tool with vertical rods is manually inserted into the openings to disengage the side ramps. Horizontal projections at the bottom of the vertical rods engage the undercuts and allow the user to disengage the side ramps by lifting upward on the tool.

The illuminated anti-trip cable duct may also be used to illuminate raceways or paths, such as aisles in auditoriums or churches. The anti-trip cable duct incorporates an integrated light transmission window and electroluminescent wire. Installation is straightforward and very similar to installation of standard, non-illuminated cable duct. Unlike rope or string lighting, which may not be arbitrarily cut, the present invention may be cut to any arbitrary length at the job site, provided that a minimum length is used. Lengths of the present invention may be cascaded together, enabling long illumination runs. The present invention may be provided in rolled lengths, adding to ease in shipping, warehousing, and job site installation. Little additional skills are required for installation, making the present invention an attractive alternative to typical non-illuminated anti-trip duct.

A cable, supplying electrical power to an electric excavator, is placed in a U-shaped channel or recess and a strip insert of elastomeric material is placed over the cable thereby preventing debris from damaging the cable or causing subsequent removal of the cable to be difficult. The crossover is shaped particularly to provide ramps on each side for the vehicle to engage and has central load-carrying shoulders which restrict central deflection of the crossover, under the wheels of the vehicle, such that vehicle load is not imposed on the cable. A towbar, of rigid plate material or a cable or chain fixedly joins one end of the crossover whereby a tow vehicle may connect to and relocate a crossover from place to place as needed, upon removal of the cable from the channel.
