Excavator Spare Parts Sliding Arm & Boom Construction Machinery 10M sliding arm

The excavator boom is composed of an upper sliding arm and a lower fixed arm. The upper sliding body is freely extended and retracted by the telescopic cylinder, which is suitable for the excavation of subways and pits. The pioneering double-limit design reduces the running vibration of the boom and improves the service life of the cylinder. The sliding device has been changed from the previous pulley to the sliding block, which reduces the failure rate, and the wear-resistant rubber sliding block is more easily replaced and maintained.

(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.
