重(zhong)型伸(shen)(shen)縮式移動懸(xuan)臂(bei)貨架是在原有固(gu)定式懸(xuan)臂(bei)貨架的基礎(chu)上(shang)更新換代的產(chan)品，每層(ceng)的懸(xuan)臂(bei)都(dou)可以伸(shen)(shen)縮，承重(zhong)能力大(da)，每層(ceng)3000KG,操(cao)作簡(jian)單(dan)，單(dan)人可以操(cao)作，配合(he)天車(che)使用(yong)(yong)，起(qi)吊存儲非常方(fang)便(bian)，不用(yong)(yong)時懸(xuan)臂(bei)可以收縮，節省空間，不會出現撞傷(shang)情況。

伸(shen)縮式懸(xuan)臂(bei)貨架工作(zuo)原理：

特殊轉動(dong)和堅固(gu)的結(jie)構，移(yi)動(dong)部分由軸承支撐，主要框(kuang)架焊接而成，組成裝配單元，當(dang)空載和負載時，一個橫向齒狀(zhuang)，表面不光滑(hua)的驅(qu)動(dong)軸控制著(zhu)推(tui)動(dong)臂(bei)時，不能(neng)(neng)往(wang)內往(wang)外運動(dong)，使用曲柄手柄，臂(bei)能(neng)(neng)拉出，適合起(qi)重(zhong)機載物使用。

Heavy telescopic mobile cantilever racking is on the basis of the original fixed cantilever racking upgrading of products, each layer of the cantilever can be telescopic, load-bearing capacity is big, each layer of 3000 kg, the operation is simple, single person can operate, use with crown lifting storage is very convenient, need not when cantilever can shrink, save a space, not be injured.
Working principle of the telescopic cantilever shelf:
Special rotation and solid structure and moving parts is supported by the bearing, the mainframewelded together, component assembly unit, when the no-load and load, a transverse dentate, not smooth surface of the drive shaft controls the driving arm, not inward outward movement, using the crank handle, pull arm can be , suitable for crane cargo.
