SUP Long Reach Front is specially designed for excavators on long distant earthmoving needed situation, which can offer your machine an exceptional extended operating range,it's an ideal work tool for river and sea dredging, pond and deep foundation excavation and slope finishing projects.

1)SUP Construction Equipment Co.Ltd. adopt latest CAD making drawings and advanced FEM (Finite Element Method) to analyze the stress distribution of long reach boom, through which we optimize the structure the best,thickness of every steel plates are strictly selected, to make sure each our attachment is strong and reliable.

2)Material cutting is done by advance CNC flame plasma cutting machines.

3)Every steel plates are well beveled before welding, straight plates are beveled by large milling machine, circular or arc area are beveled by OTC plasma cutting robot,this can improve the welding quality greatly.

4)Welding is done partly by skillful workers with at least 4 years experience, and partly by robotic welding machine, excellent welding quality is guaranteed.

5)Ultrasonic flaw detector is used to detect products to ensure every welding beads are good enough. 

6)Surface treatment for the products processed in Large sandblasting room,the treatment can release surface stress of product, remove dirt,improve the adhesive force between the paint and products surface.
