重型伸縮式移動懸臂貨架是在原有固定式懸臂貨架的基礎上更新換代的產品，每層的懸臂都可以伸縮，承重能力大，每層3000KG,操作簡單，單人可以操作，配合天車使用，起吊存儲非常方便，不用時懸臂可以收縮，節省空間，不會出現撞傷情況。

伸縮式懸臂貨架工作原理：

 特殊轉動和堅固的結構，移動部分由軸承支撐，主要框架焊接而成，組成裝配單元，當空載和負載時，一個橫向齒狀，表面不光滑的驅動軸控制著推動臂時，不能往內往外運動，使用曲柄手柄，臂能拉出，適合起重機載物使用。

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.
