Q1: How long is the boom arm can the min excavator be configured with? Whether it is necessary to increase the counterweight?
A1. 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, and 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 the longest length as min excavator is easy to slosh.

A2: It depends on the installer and machine size.
Usually disconnecting the original boom arm, stick cylinder, then pin the new one is okay.
