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 Ushaped 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.
摘要翻译：高强度弹性体材料的便携式交叉，例如聚氨酯树脂，其被放置在高吨位地球运动车辆的路径中的地面上。向电动挖掘机提供电力的电缆被放置在U形通道或凹槽中，弹性材料的带状插入物放置在电缆上，从而防止碎片损坏电缆或导致电缆随后的去除困难。交叉形状特别地用于在每一侧上提供用于车辆接合的斜面，并且具有中心承载肩部，其限制在车辆的车轮下方的交叉的中心偏转，使得车辆负载不施加在电缆上。刚性板材的拖杆或电缆或链条固定地连接在交叉部分的一端，由此当从通道中取出电缆时，两个车辆可以根据需要连接到一个交替位置并将其重新定位到另一个位置。
