Product Presentation of Excavator Extension Arm
The long arm of the excavator is made of Q355B steel, which has
good strength and rigidity. The shaft sleeve of the extension arm
is generally made of 45 # steel, with a 40Cr bushing inside, and
the lubrication effect of butter reduces the shear force generated
by the frequent rotation of the shaft and the shaft sleeve, thereby
improving the service life of the shaft sleeve. The structure of
the extension arm of the excavator is generally a box-type
structure, that is, the upper and lower cover plates are combined
with the left and right wall plates. The buffer strip needs to be
welded inside, and the buffer strip must have an oval hole, which
can be released better. The stress generated by the extension arm
during welding work can avoid damage to the extension arm.
