The Anti-Bend Performer: A High-Reliability Mechanical Boom for Extended Service

• Custom Long-Reach Boom
• Excavator Piling Boom Attachment
• CB Series Extension Arm
• High-Strength Excavator Boom
• Pile Driver Reach Extender

The YEKUN CB Series represents a line of high-performance, custom-engineered long-reach booms designed to transform standard excavators into capable long-range piling rigs. Manufactured by Shanghai Yekun Machinery, these booms extend the machine's working radius, enabling the efficient installation of foundation piles up to 12, 15, and 18 meters in length. Ideal for deep foundation projects, waterfront construction, and other applications requiring extended reach, the CB-12, CB-15, and CB-18 models are built to integrate seamlessly with 30 to 60-ton excavators.

Our booms are engineered from the ground up for durability, reliability, and seamless job-site integration, addressing the core challenges of heavy-duty, extended-reach piling.

• High-Strength Construction: The boom structure is fabricated using high-strength steel and robust welding techniques. This design philosophy prioritizes resistance to bending and structural fatigue under continuous, high-load piling operations, ensuring safety and frame longevity.
• Enhanced Wear Protection: Critical stress points, such as connecting axles, are fitted with specifically designed, thicker alloy covers. These components provide superior wear resistance, reducing friction and material degradation at pivotal joints, which directly translates to a longer service life and reduced maintenance frequency.

• Integrated Hydraulic Layout: The hydraulic system features a rational, custom-engineered layout that matches the host excavator's architecture. All pipe joints are secured with argon arc welding, ensuring a leak-proof, high-pressure circuit that delivers reliable performance and minimizes the risk of downtime due to hydraulic failures.
• Unified Lubrication Design: For ease of maintenance, the lubrication points on the boom are aligned with the excavator's own lubrication system. This allows operators to perform essential greasing quickly and consistently during regular machine maintenance checks, promoting optimal component health and further extending the attachment's operational lifespan.

Select the model that matches your required pile depth and carrier size.

Q: What is the primary purpose of the YEKUN CB Series boom?

A: It is a custom long-reach attachment that enables standard excavators to function as piling rigs for installing deeper piles (up to 18 meters) and working at longer horizontal distances, which is essential for projects like deep foundations, bridge work, and shoreline construction.

Q: Can this boom be adapted to fit my specific excavator model?

A: Yes. While designed for broad compatibility within the 30-60 ton range, a key advantage is our focus on customization. We can tailor mounting interfaces and hydraulic layouts to ensure optimal fit and performance with your specific machine model.

Q: How does the design ensure durability in tough piling conditions?

A: Durability is multi-faceted: it starts with the high-strength steel construction to prevent bending, includes wear-resistant alloy reinforcements at high-stress points, and is supported by a professionally welded hydraulic system and easy-access lubrication to prevent premature wear.

Q: Who manufactures these booms, and what is their expertise?

A: They are manufactured by Shanghai Yekun Machinery Co., Ltd., a company founded in 2014 that specializes in hydraulic vibratory pile driving equipment. Their expertise in piling technology directly informs the design of these robust, application-specific attachments.

Q: What is the typical lead time and what are the payment terms?

A: Lead times vary based on model and customization level. We accept standard international payment methods such as T/T and L/C. Detailed delivery schedules and terms are provided upon order confirmation.

Q: Does the boom come with a warranty?

A: Yes. We stand behind the quality of our products. Please contact us directly for specific warranty information related to the CB Series long-reach booms.
