Characteristics and material of lengthening arm
It is precisely because the standard arm length of excavators can not meet some working conditions, so excavators use lengthened arm to fill this blank.
The lengthening arm is generally made of Q345B steel, which has better strength and rigidity. The shaft sleeve is generally made of 45 # + 20 #. The 40Cr bushing is inlaid inside, and the lubricating grease is added, which greatly reduces the shear force of the shaft and sleeve during frequent rotation, thus increasing the service life of the shaft sleeve.
