How it works
The excavator sliding arm is extended and retracted by the go and back of oil cylinder, to gain a bigger digging radius and digging depth.
The outer telescopic arm is composed of two parts: the upper sliding arm and the lower fixed arm.
The upper sliding arm is installed above the lower fixed arm, and the movable body is formed up and down by both sides rollers and rails.
By the expansion and contraction of the telescopic cylinder, the upper sliding body is pushed forward and backward to freely expand and contract.

Its main components are a fixed body, moving body, slider, telescopic cylinder, etc.
Strength
The upper sliding arm can bear large force with a simple structure, adjust its working radius and digging depth flexibly,
easy to operate, highlight its advantages on digging foundations, basements, caisson, subways, etc.
