well-hole wagon

基本解釋

But well-hole wagon is applicable for the transport of out-of-gauge and overweight cargos, such as the transformers, generators, rolling mills, reactors, and high-pressure boilers, etc.
而落下孔車適用於運輸超限超重型貨物，如變壓器、發(fā)電機(jī)、軋機(jī)牌坊、反應(yīng)器、高壓鍋爐等，研制大噸位的落下孔車是國民經(jīng)濟(jì)發(fā)展的急需。
