許多流量站已在河道断面上架設了鋼絲过河纜。这些鋼絲纜繩必須不时地上油。有些站的鋼絲纜本来安裝在絞关上,上油时十分方便,只要松动絞关,把鋼絲纜放下来,使它垂近河面,站在船上就可往纜繩上擦油。但有些站的过河纜,没有裝絞关,而是固定在河岸上的,往纜上擦油就特別費勁。这些站是用 Many stations have set up wire crossings at the river cross-section. These wire cables must be oiled from time to time. In some stations, the steel cable was originally installed at the twist-off and was very convenient for oiling. As long as the twist-cord was loosened, the cable was lowered to bring it close to the river and the ship was allowed to rub the oil on the cable.
