Introduction of Excavator Sliding Boom
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.
Structure
A telescopic cylinder is installed in the upper sliding arm, the
cylinder body is fixed on the lower fixed arm, and the cylinder
piston rod is fixed on the upper sliding arm.
Its main components are: fixed body, moving body, slider,
telescopic cylinder, etc.
Characteristic
Our sliding arm is durable and can do heavy work and dig hard soil.
The sliding arm has a simple structure, low failure rate, easy
maintenance and longer service life. Basically, if the sliding arm
is under normal maintenance, the slider only needs to be replaced
once a year, and other issues do not need to be considered. The
sliding arm can be used for diagonal digging or support.

Advantages of Excavator Sliding Boom
(Easy to maintain)
ZHONGHE silding arm adopt antiwear nylin sliding plates rather than
traditional pulley, which can be replaced quickly and conveniently.
(Robust sliding structure)
1. The lower cover of the upper sliding arm and the upper cover of
the lower fixing arm are both 20mm.
2. Cover plates are cut from a whole piece but not spliced, so as
to be more firm and not easay to deform.
(Avoid oil leakage)
The double oil seal design for the built-in telescopic cylinder
prevents hydraulic oil from leaking, prolongs the service life of
the sliding cylinder
(Long service life)
1.Double limit design of the sliding cylinder prevents cylinder
jolting and over pulling.
2.Steel sliders are welded between the skateboards to resists wear.
