FAQ of Long Reach Excavator Boom

 

Q1: Why not have boom and stick cylinders in the plan?

A2. Generally speaking, 30-40 excavator longest arm suggests to be 8 meters, can configure 0.1 cbm bucket, no need extra counterweight. 55 excavator longest arm suggests to be 12 meters, can configure 0.1-0.15 cbm bucket, need 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 longest length as min excavator is easy to sloshing.
