下面将研究三种藉电动拖车牵引船只过闸的纵剖面图。这些剖面图及牵引方法并不是包括齐全了,还有其他的型式。例如适应于梯级船闸牵引的就有架空缆车、固定绞盘、环式(?)索等等。它们都可实际应用于各种通航建筑物中。就船闸而言,在选择船只牵引方式之前,首先应从技经观点来研究船闸的纵剖面,只有在确定了船闸最有利的纵剖面后,才分析牵引船只的方法。如果认为必须采用岸边牵引时,再选择一两种型式进行较详细的研究。本文主要是研究电动拖车牵引木筏及船队通过梯极船闸的具体方式,至于选择牵引方式前一阶段的工作内容,这里不准备谈。电动拖车牵引船只过闸是用拖(?)将拖车与为首
In the following, three types of longitudinal cross-sectional views of the trawler passing through an electric trailer will be studied. These profiles and traction methods are not complete, there are other types. For example, there are ropeway, fixed winch, ring (?) Cable and so on adapted to the traction of cascade lock. They are all practical applications in a variety of navigable buildings. In the case of a ship lock, before choosing a way of towing a ship, the longitudinal section of the ship lock should first be studied from a technical and economic point of view. The method of towing a ship should only be analyzed after determining the most favorable longitudinal section of the ship lock. If you think you have to shore-pull, choose one or two more types for a more detailed study. This paper is mainly about the specific way of towing rafts and their fleet through the ladder pole of the electric trailer. As for the work content of the previous stage of choosing the towing method, it is not prepared to talk about here. Electric Trailer The towing vessel is towed with a trailer (?)
