CAT 350 Excavator Piling Arm | Heavy Duty Custom Pile Driving Boom

EXCAVATOR PILE DRIVING ARM & BOOM

The CAT 350 Piling Arm is a heavy-duty excavator attachment specifically designed for Caterpillar 350 series excavators (45–50 ton class), engineered to deliver stable and efficient pile driving performance in demanding foundation construction environments.

This piling boom is widely applied in bridge foundations, port and wharf projects, highway construction, industrial facilities, and large-scale municipal works, where high load capacity, strong vibration resistance, and precise pile positioning are required.

The structure adopts a reinforced box-type design manufactured from high-strength steel, providing excellent rigidity and fatigue resistance under continuous pile driving operations. Optimized structural geometry and balanced weight distribution help maintain machine stability when operating with vibro hammers or hydraulic pile drivers.

Each CAT 350 piling arm is custom-built according to hammer weight, pile type, and jobsite conditions, offering a reliable and practical piling solution for contractors and equipment operators.

 ▎KEY FEATURES

✔ Heavy-Duty Reinforced Structure

Designed for continuous operation under high impact loads.

✔ Stable Pile Vertical Control

Improves pile alignment and reduces deviation.

✔ Optimized Machine Balance

Ensures safe and smooth operation during lifting and driving.

✔ Wide Equipment Compatibility

Suitable for vibro hammers and hydraulic pile drivers.

✔ Project-Oriented Custom Design

Customized arm length and configuration for different sites.

 ▎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.

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)

 ▎CERTIFICATTES & FACTORY HISTORY

We were originally affiliated to a Singaporean private factory in China. We have always only served the excavator industry and have a lot of data and manufacturing experience. Provide professional excavator accessories for dealers in many countries around the world.We insist on quality first, and deal with details so that brand dealers appoint us as partners.
