2.Why not have boom and stick cylinders in the plan?

3. Are you alaways delivered on time?
We can't promise about the freight but what we can do is shortening our lead time while keep the same quality level. So there will not be any problem even if the sea freight delay for a couple days. Our annual output of various types of excavator boom arms can reach 600 sets.
4. How long is the boom arm can mini 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.
