(Our engineers have focused on excavator boom and attachment over 10 years)

3. Long excavator boom shall be two/three jointed pcs to make it fittable into container to save shipping cost

According to customer requirements design and production of two-stage excavator elongated arm, mainly suitable for earth and stone foundation and deep cut excavation operations; It is widely used in river dredging, port construction, subway construction and building foundation excavation, with wide operating range, high efficiency and high safety.

When users extended arm in order to save costs, we carefully analyzed the original car which accessories can use back to the original, which is must be replaced, replace standard arm extended arm of standard configuration is as follows: lengthen the forearm a, scoop a, 4 a bucket cylinder, hoses, butter tube 3, a connecting rod assembly, transportation, a connecting rod, pin 6.

1. Long reach excavator boom

2. Excavator telescopic boom

3. Demolition boom

4. Excavator rock bucket

5. Excavator tilting bucket

6. Hydraulic grabs for excavators

FIRST--CORE CRAFT TECHNOLOGY
 

1. Less maintaince

2. Strong and sturdy

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.
