EXCAVATOR LONG REACH ARM & BOOM

CAT336

The machine pictured is currently in construction in Kuching, Malaysia. Choose a long or extra long arm and you'll be able to reach farther and dig deeper. These excavator arms are particularly useful in applications where space is limited to properly reposition the machine, such as downhill slopes.

 CONFIGURATION SITUATION

 

STEEL CUTTING

The incision is flat to ensure the accuracy of cutting steel plates

 

 GROOVE WELDING

 

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.

Orbital welding machines are used for welding, and manual strengthening and welding are performed at corners and reinforcements.

Our boom and arm are large-welded box structure and thick or multi-plates for high-stress areas.

Also the inside have strength plate make it more stronger.

 

 LARGE BORING MACHINE -- BUTT BORING

The processing efficiency is higher, the precision is better, and the product quality and labor efficiency are greatly improved.

 

 SURFACE TREATMENT OF WORKPIECE--SHOT BLAST 

The small steel balls of the large shot blasting machine are used to hit the surface of the workpiece to remove the rust and small impurities on the surface of the steel plate, so that the surface of the workpiece presents the original metallic luster and increases the adhesion of the primer.

 

 PRIMER AND PAINT TREATMENTS

Spray with the same paint as the brand excavator factory to ensure consistent color.

 

 HIGH PRESSURE HARD PIPE & PIPELINE BENDING TREATMENT

  

1. Friction welded flange and oil cylinder - use machine high-speed friction welding, which has higher efficiency and avoids artificial false welding and air bubbles.

 

2. Automatic pipe bending machine - use numerical control to control the degree of bending of the pipeline, and automatically bend the seamless steel pipe, with higher precision.

 

 PAINT / PACKAGING / TRANSPORTATION SERVICES

 

1.The color paint is consistent with the brand excavator factory (customizable color), using high-quality paint to make the product more delicate and beautiful.

 

Long Reach Arm and Boom

2. We use stretch film to package the product. (Three-plywood wooden frame needs to be noted)

 

3. We have cooperated with many shipping companies in China for many years,and the transportation service and efficiency are very good. (Recommend FOB/CIF/CNF)
