-This long boom arm design also different from our standard design,it's stick cylinder is been set under the boom,our standard is on the top of the boom
This design can get bigger work range(Max reach,Max cut depth,Max cut height),but the stick excavating power smaller,because cylinder act to shorter length when excavating.
If projects do not need high strength excavating,can use this design to get larger work range.
