01 Use Q355B material,
02 Adopts precision steel pipeline
03 Adopt alloy copper sleeve big arm base
04 Two layers groove welded to ensure
05 Double quality inspection before leaving
06 The tolerance of position size within 1 mm
07 Angle of boom and arm can reach 163°
Tolerance within 5-10um, ensure the accuracy of hole
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.
