Product Presentation of Excavator Extension Arm

  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 the shaft sleeve is increased. The long arm excavator can complete the excavation work very well, and its work efficiency is very high, not only can be well excavated and used but also the speed is very fast, which greatly improves the work efficiency of the workers and provides convenient demand for construction.

FAQ of excavator long arm

Q1: Why not have boom and stick cylinders in the plan?
A1: First, the whole long arm is lengthening, but the boom just lengthening from its middle sleeve to its end, so the original boom and stick cylinder can be used. Second, using the original parts can save you cost.
 
Q2: How long is the boom arm can min excavator be configured with? Whether it is necessary to increase the counterweight?
A2. Generally speaking, the 30-40 excavator longest arm suggests to be 8 meters, and can configure 0.1 cbm bucket, with no need for an extra counterweight. 55 excavator's longest arm suggests to be 12 meters, which can configure 0.1-0.15 cbm bucket, which needs 0.5 ton extra counterweight. 60-80 excavator longest arm suggests to be 12 meters, can configure 0.15-0.25 cbm bucket, need 0.5-0.7 ton extra counterweight.
It is not recommended to extend boom arm to longes the t length as mini excavator is easy to slosh.
 
Q3: How long will it take tall an excavator long reach boom?
It depends on the installer and machine size.
Usually disconnecting the original boom arm, stick cylinder, then pin the new one is okay.
Kindly remind, use
