Construction Machinery Extended Arm *4meters Long Boom SANY**5 Excavator Long Reach Front

^{Description:
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 river, dredging sea, dredging port,etc}

<sup>Our Advantages:
1. We have more than *0 years of experience in customizing all kinds of long boom for all kinds of excavators.
And we have detailed dimensions of most excavators, so just giving us the excavator model is ok.</sup>

^{For this SANY**5 Excavator, we also have detailed dimensions.}

^{2. Main sheet Material of this SANY**5  excavator long reach boom is Q**5B + Q**0D, the top and bottom cover plate of the boom and stick is Q**0D,and other sheet is Q**5B, Pins material is *2CrMo4.}

<sup>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 *0% Argon and *0% CO2 mixed.</sup>

^{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 a stop valve on both ends, it's easy to replace attachments.}

^{6. For big excavators with long material handling arms, we usually adopt a cast base, much stronger.}

^{7. For all long boom we produced, will supply 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 excavators (tonnage higher than *0ton), we advise using the original stick cylinder, original cylinder quality is much better.}
