CAT349 long arm customized extended long reach excavator arm for river dredging

Chinese Manufacturer Customized Extended Long Reach Arm CAT349DL

CAT349DL Long Reach Excavator with Extension Long Reach Arm for Deep Digging and Open Caisson China Factory manufacture High Quality

The CAT349DL Long Reach Excavator Boom and Arm is designed for projects that require extended reach and efficient deep excavation while maintaining machine balance and operational safety.

Built to match the CAT349DL platform, this long reach excavator attachment features a strengthened boom structure, optimized working geometry, and reliable hydraulic performance. It allows operators to work at longer distances with improved accuracy and reduced machine repositioning.

The CAT349DL long reach boom is commonly used in river dredging, canal cleaning, slope shaping, deep pit excavation, and waterfront construction projects.
Boom length, arm configuration, and bucket capacity can be customized based on working depth, soil condition, and project requirements.

This solution offers a practical balance between reach, stability, and productivity for medium-size excavation jobs.

CONFIGURATION SITUATION

 STEEL CUTTING

•use the plasma cutter 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 WORK PIECE--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

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

• 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

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

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

•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)
