The factory of excavator boom and stick long introduce
The long arm of the excavator is made of Q355B steel with good
strength and rigidity. The shaft sleeve of the lengthened arm is
generally made of 45 # steel, with 40Cr bushing inside, together
with the lubricating effect of butter, it reduces the shear force
produced when the shaft and the sleeve rotate frequently, thus, the
service life of shaft sleeve is increased. The excavator long arm
structure is generally a box-type structure, that is, the upper and
lower two cover plates, plus the left and right two sidewall are
combined to form, the inside needs to be welded with buffer bars,
and the buffer bars must be opened with elliptical holes, this can
better release the extension arm in the welding work produced by
the stress, to avoid damage to the extension arm.
