FAQ of Long Reach Excavator Boom

 

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 middel sleeve to its end, so the original boom and stick cylinder can be used. Second, using the original parts can save your cost.

 

Q2: How long is the boom arm can min excavator be be configured with? Whether it is necessary to increase the counterweight?
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.
