    SANY305 Extended Long Reach Excavator Booms 24 Meters Q355B Material , Excavator Long CAT320D

    Zhonghe 20 Ton 18m Long Reach Excavator Booms Arm For CAT320D

    Long reach excavator is a large work range and can fulfill lots of projects that need larger work range requirements for excavators.
    Long reach boom is very popular in lots of constructions, such as subway construction, dam construction, etc
    Long reach boom is also very popular and highly efficient in dredging work, dredging rivers, dredging sea, dredging ports, etc


    1. We have more than 10 years of experience in customizing all kinds of long booms for all kinds of excavators.
    And we have detailed dimensions of most excavators, so just giving us the excavator model is ok.
    For this SANY305 Excavator, we also have detailed dimensions.
    2. Main sheet Material of this SANY305 excavator long reach boom is Q345B + Q690D, the top and bottom cover plate of the boom and stick is Q690D, and another sheet is Q345B, Pin’s material is 42CrMo4.
    3. Before welding, we have to use a big edge milling machine to mill the edge of the sheet. So the welding can go to the internal of the steel sheet and make the structure have higher performance.
    4. Our Welding is protective gas welding, the protective gas is 80% Argon and 20% CO2 mixed.
    5. If your long boom needs an extra auxiliary hydraulic pipe for the breaker or other attachments, we also can prepare it for you.
    And the auxiliary pipe also has stop valves on both ends, it's easy to replace attachments.
    6. For big excavators with long material handling arms, we usually adopt cast base, much stronger.
    7. For all long boom we produced, will supply the following parts:
    Bucket:1 pcs
    Linkage:1 kits
    Bucket cylinder:1 pcs
    Hydraulic pipe:1 kits
    Lubricant pipe:1 kits
    Counterweight(if need):1 pcs
    Stick cylinder: Can match the original stick cylinder to save cost, if you need it, we also can prepare it.
    For bigger excavator(tonnage higher than 50ton), we advise using the original stick cylinder, the original cylinder quality is much better.

    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.
