1.Material :
A.)All Q355B Steel for standard long reach boom (strenght:345Mpa).
B.)Heavy-duty long reach boom and excavator tonnage above 40ton :we use Q690D high strength steel (strength:690Mpa,same as
Weldox700 in Europe )
2.Internal view(spaced by vertical and horizontal reinforcement plate at regular interval)
3.All steel plate are beveled by beveling machine before welding.
4.Welding:
A.) Welded with mixed gas between argon and carbon dioxide. Argon content:80%.Carbon dioxide content:20%.
B.) Welded by auto-welding machine .
5.Pins:
All of our pins are hardened (to enhance hardness), tempereded(to enhance toughness) and grinded .
So our pins costing is very high and we never had problem with our pins.
6.)The cylinder :
