PC350 Komatsu reinforced 18meters super long reach front long reach
boom and arm
The video show of dipper arm extension
Product advantage of long excavator boom and arm:
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°
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.
Scope of application:
It is mainly suitable for earthwork foundation and deep cutting
excavation. It is widely used in river dredging, port construction,
subway construction and building foundation excavation, with wide
operating range, high efficiency and high safety
Product advantages:
1. The plate is made of wear-resistant and high-temperature
resistant square steel, and the tensile strength of the plate is
high. Each plate has been verified by the inspection agency.
2. The upper shaft sleeve of the arm adopts the German standard
JSUN super-grinding alloy shaft sleeve. During the movement of the
excavator extension arm, each hole of the shaft sleeve can be
automatically oiled, and there is no blind spot for lubrication,
which makes the excavator extension arm work more smoothly. .
3. The pipeline on the extension arm of the excavator adopts
standard precision phosphating tube to prevent problems such as oil
tube blockage.
4. Professional welding technology, full and regular welds, and
every weld is tested by weld flaw detection.

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.
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.
