水電站龍門起重機(jī)英語(yǔ)例句參考：

Hydropower Station Gantry Crane: mainly used for lifting and opening and closing gates, but also the installation. Lifting capacity of 80 to 500 tons, spans less 8 to 16 meters; lower lifting speed for 1 to 5 m / min. This crane was being lifted, although not always, but once the work was very heavy use, so an appropriate level to improve the work.

水電站龍門起重機(jī):主要用來(lái)吊運(yùn)和啟閉閘門,也可進(jìn)行安裝作業(yè)。起重量達(dá)80～500噸,跨度較小,為8～16米；起升速度較低,為1～5米/分。這種起重機(jī)雖然不是經(jīng)常吊運(yùn)，但一旦使用工作卻十分繁重，因此要適當(dāng)提高工作級(jí)別。
