Usually use 40GP container to load product !
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.
Q3: How long will it takes to install a excavator long reach boom?
It depends on the installer and machine size.
Usually disconnect the original boom arm, stick cylinder, then pin
the new one is okay.
Kindly remind, prepare several containers to fill the oil before
disassemble.
