luffing crane在金山词霸中有两种解释:
(1)水平起重机
(2)俯仰式起重机, 鹅头伸臂起重机
Store cranes to be installed and arranged SB and PS for pro vi sions and spare parts as per General Arrangement. (Cranes can be combined MOB-boat/ life-raft/provisions). Only one crane to be of luffing type for spare parts and provisions.
其中
Only one crane to be of luffing type for spare parts and provisions.
那这里luffing type到底是那种啊?
请大家指点啊!谢谢了。。。
