No.1 Selling Professional Team Excavator Long Boom long reach excavator reach with bucket excavator long arm excavator arm Long Boom Excavator For Sale

Our long reach excavators are built with high strength and high tensile alloy steel Q355B, with the option to upgrade to a higher quality 690 material.

These excavator arms are designed with internal baffles for added strength and durability, allowing them to withstand torsional loads.

The excavator arms and buckets are constructed with large welded box-type construction, with thick plates or multi-piece construction in high stress areas.

We offer high quality accessories including pipes, pins, bushings and cylinders.

Upon request, we can install a pre-installed camera system.
For added safety, an optional lockout valve is available to prevent the arm from dropping in the event of a hydraulic hose failure.

We offer a wide range of accessories to suit excavator long reach applications, including standard digging buckets, mud buckets, aggregate buckets and clamp buckets.

 

 

How can we ensure the quality of our excavator long arm
For Materials:
The primary material of the boom and arm is Shaogang Q355B and Q690D, the Hydraulic tubes are national standard precision seamless, and the pins are 40MuCr, The high-pressure hoses consist of four layers of steel rings, while the grease pipe is a single-layer hose. The bushing, driven into the base of the boom, is made of graphite alloy copper sleeve.
 
Our production process:
1. The extended arm plate is precision-cut using a plasma cutting needle to ensure accuracy.
2. Before welding, the plate edges are milled (tapered) using a large edge milling machine. This allows for deep penetration of the weld into the steel plate, enhancing the overall performance of the structure.
3. Flaw detection tests are conducted using specialized instruments after welding.
4. After welding, a double-sided large-scale floor-standing boring machine is employed for precision boring. This ensures the long-reach arm concentricity during operation and extends its service life.
5. Following grinding, a sandblasting process is carried out to achieve a specific level of roughness and cleanliness on the long arms. This enhances their strength, hardness, and corrosion resistance.
 
Precision:
1. Tolerance within 5-10um
Hole drilling tolerance is within 5-10um, ensure accuracy.
2. Reach deeper and higher
The max work range and the max digging height are larger as the angle of the boom and arm can reach 163 degrees.
3. High work efficiency and saving fuel
Lighter while taking into account the quality, not only ensures work efficiency but also saves fuel.
Technical staff:
Our chief engineers have experience customizing different kinds of long stick excavators over 10 years.
We have customized more than 100 heavy-duty long excavator booms for powerful excavators (crawler or floating platform), like EX2500, EX1200, EX1900, and SY980.
