Product Advantages:
1. The plate is wear-resistant and high-temperature resistant
square steel with high tensile strength. Each plate is verified by
the inspection institution
2. The shaft sleeve on the arm adopts the German standard JSUN
super-runin gold shaft sleeve. In the process of movement, each
hole of the shaft sleeve of the excavator can automatically oil
out, and the lubrication is free of blind area, so that the
excavator and the long arm can be more smoothly in the process of
work.
3. The excavator lengthened the upper arm pipeline and selected the
standard precision phosphating pipe to prevent tubing blockage and
other problems.
4, professional welding technology, full weld rules, every weld
after weld inspection.

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.
Q3: How long will it takes to install a excavator long reach boom?
It depends on the installer and machine size.
