^(3)Features:

^{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 :

      We purchase from S-any Company .So the quality of  cylinder is very reliable .


6.)The painting : 

 We use JAPAN "KANSAI" paint ,they are the supplier of the excavator factory ,like HITACHI ,KOBELCO and so on ,
 we can insure the color 100% match with original machines' color,and making sure our paint does not fade during
long time use .
