Product Presentation of Excavator Boom
The long arm is made of Q355B steel with good strength
and rigidity. The shaft sleeve of the extended arm is generally
made of 45 # steel, with a 40Cr bushing inside, and the lubricating
effect of butter, which reduces the shear force generated when the
shaft and sleeve rotate frequently, thus improving the service life
of the shaft sleeve. The scope of use is relatively large, but its
main role is to improve the excavation radius, in the river
dredging, land reclamation, subway entrance excavation, pedestrian
underground tunnel, highway parapet repair, and l residential
cement transport.
