High strength portable cable crossover for high tonnage earth moving vehicles

摘要

A portable crossover of high strength elastomeric material, such as polyurethane resin, which is placed upon the ground in the path of a high tonnage earth moving vehicle. 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 two vehicle may connect to and relocate a crossover from place to place as needed, upon removal of the cable from the channel.
