河北升降貨梯http://www.qdysj.net/臂架順序伸縮是一種順序伸縮，同步伸縮就是設(shè)備上的各個(gè)節(jié)臂以相同的形成比率同時(shí)伸縮，并沒(méi)有誰(shuí)先誰(shuí)后，而獨(dú)立伸縮是一種比較難理解，和最復(fù)雜的伸縮方式，河北升降貨梯上的動(dòng)作之件沒(méi)有聯(lián)系，可以獨(dú)立完成不同的動(dòng)作。
Shandong lowering a telescoping boom sequence is a sequence stretching, simultaneous stretching each boom section is on the device at the same rate at the same time the formation of stretch, and not who should and who,independent of stretching is a more difficult to understand, and most complex stretching, the movement of the goods Shandong lifting each section of the arm member not linked, you can perform different actions independence.
