Two section telescopic boom telescopic arm concrete pump excavator long reach boom CAT320D
According to its structural appearance can be divided into: external expansion and internal expansion; [1] External expansion is the free expansion of the moving body above the fixed body through the action of the expansion cylinder and the slider. Internal expansion is that the moving body is inserted into the fixed body, and the moving body is extended and retracted through the expansion of the telescopic cylinder
According to its working principle, it can be divided into: sequential scaling and synchronous scaling. The sequential expansion is driven directly by the oil cylinder by means of multistage cylinder or multiple single-stage cylinder. Synchronous expansion adopts single cylinder plus steel wire rope and pulley assembly to achieve expansion.
