散货装船时,为了充分利用舱容和有利航行安全,必须进行平舱作业.此平舱作业在旧式的小舱口船舶上是一个非常突出的问题,即使是大舱口的散货专用船舶,也是需要考虑的.随着装卸机械化的发展,为了适应不同船型的需要,人们不断研究简便适用的平舱装置.以往多使用各种机械抛料式平舱机,如:曲带式平舱机、直带式 In bulk shipments, in order to take full advantage of the bulk and to facilitate the safety of sailing, it is necessary to proceed with the trimming operation, which is a prominent issue on the old small hatchcraft, even for the large hatch bulk cargo Ships, but also need to be considered.With the development of loading and unloading mechanization, in order to meet the needs of different types of ships, people continue to study the simple and convenient for the use of the horizontal plane device.In the past, the use of a variety of mechanical thrower planing machine, such as: Cabin aircraft, straight belt
