0.4-0.5CBM Excavator Long Reach Boom 16 Meter Durable Fit CAT320
1. Applicable for all the make and model of the excavator.
2. Many different materials such as Q345B, and Q690D are optional to suit your
application.
3. Big boom can be two jointed pcs to make it fittable into a container to save
shipping costs.
4. All the seams are 45 degrees tapered before welding.
5. All parts have a warranty
6. Some parts can be consolidated using a thicker plate or overlapping another plate
for heavy-duty application.
7. The boom cylinder and arm cylinder can also be supplied if the customer wants.
8. Extra pipelines can be added to suit some extra applications.
9. The conventional material is Q355B. The plate is thin, high in strength, and light
in weight, and reduces the load of the excavator.
10. The bushing in the boom seat cover is made of copper (with self-lubricating carbon
powder inside to extend the life of the 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.
Usually use 40GP container to load product !
