Use computer programming and then use automatic pipe bending equipment to arrange oil pipes
After shot blasting, apply primer, topcoat and varnish to make the parts more shiny and the paint of the product can be retained for a longer time.
Company Services
1, Long reach boom are use for dredging rivers port construction, railway construction and groundwork construction, with high extensive operation scope, high efficiency and high security.
2, Our company was founded in 2008 with more than 10 years of experience, production line engineers have more than 10 years of data and experience for all brands of excavators designed and customized long range booms.
3, Applicable for all the excavator model,OEM service is also available.
4, Advanced manufacturing process, Technique is in the line with global standards.
5, We have all the installation dimensions of most excavator, we can customize this long reach boom for your excavator.
6, Before welding, we have use big edge milling machine mill(taper process) the edge of the sheet. So the welding can go to the internal of the steel-sheet and make the structure have higher performance. Also the inside have strength plate make it more stronger.
7, If necessary, extra pipeline can be added to suit to some extra application.
8, Stick cylinder of the long boom, can use your original stick cylinder to save the cost, if you need the stick cylinder, we also can prepare for you.
9, Some parts can be consolidated using thicker plate or overlapping another plate for heavy-duty application.
10, Welding is protective-gas welding, the protective gas is 80% Argon and 20% CO2 mixed. This is golden standard for protective gas.
11, Before welding, we have use big edge milling machine 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.
12 .We can customize the arm for all kinds of excavator as per your request. Just let me know your request.
13. If you need, some parts can be consolidated using thicker plate or overlapping another plate for heavy-duty application, just let me know.
14. Not make the bucket for this extender arm as customer request. But if you need us prepare the bucket for you, that's
