如所周知,向海船的货舱装载沉重的货物是很困难的。有些货物虽然可以利用叉车,但对于重货,或者由于货舱进口的地面已被占用以后,便无法利用叉车了。因此在装运例如重达3～5吨的重货时,就必须用5吨起重机直接向船舱装载,而将较轻的货物装在甲板下边或两层甲板之间。为了方便并加速这种装载工作,特推荐一种按剪刀原理工作的装载设备,图1表示此设备在排量为11500吨的货船船舱里进行装载的情况。
As we all know, it is very difficult to load heavy loads on a ship’s hold. Although some trucks may use forklifts, forklifts can not be used for heavy loads or because the ground imported into the hold has been occupied. Therefore, for example, when carrying heavy cargo weighing between 3 and 5 tons, it must be loaded directly into the hold using a 5-ton crane while the lighter cargo is placed under the deck or between two decks. In order to facilitate and speed up this loading work, a scissors-based loading equipment is recommended. Figure 1 shows the loading of this equipment in a cargo ship with a displacement of 11,500 tons.
