液壓卸貨平臺/的臂架是設備運行中的主要受力部件，它的正常伸縮才能使貨物或人完成位置件的轉換，可見這方面非常重要。到目前來說，液壓卸貨平臺臂架的伸縮方式已經變得更加多樣化了，包括了順序伸縮、同步伸縮、獨立伸縮等幾種，不同類型的設備中配備的伸縮方式都是有所不同的。
The arm of the hydraulic unloading platform is the main force in the operation of the device, it's normal to make the goods or people to complete the conversion of the position, which is very important in this regard. At present, the expansion of the platform of the hydraulic unloading platform has become more diverse, including the order of the expansion, synchronization, and other types of independent and flexible, different types of equipment in the expansion mode is different.
液壓卸貨平臺/臂架順序伸縮都是按照一定的先后次序來完成伸縮動作，為的是可以使液壓卸貨平臺各節臂伸出后的起重能力與升降機的起重特性相適應。而液壓卸貨平臺同步伸縮就是設備上的各個節臂以相同的形成比率同時伸縮，并沒有誰先誰后。獨立伸縮也很容易理解，液壓卸貨平臺的各個節臂的動作之件沒有聯系，可以獨立完成不同的動作。
In order to complete the expansion of the hydraulic unloading platform, the lifting capacity of the crane can be adapted to the lifting capacity of the crane. While the hydraulic unloading platform is synchronized with the same ratio of the various sections of the device at the same time stretching, and no one who first. Independent expansion is also easy to understand, the hydraulic unloading platform of the various sections of the arm of the action is not linked, can be independent of different action.
