Factory Sale 10-24m Excavtaor Long Boom Arm, Long Reach Excavator for Hitachi Kobelco Sany Excavator

1. Premium Materials: The excavator boom arms are constructed from high-strength Q355B steel (with Q690B available as an option). Hydraulic pipelines utilize precision seamless tubes compliant with national standards, while pins are made of 40CR alloy steel. High-pressure hoses are reinforced with four steel wire layers, and grease lines feature a single-layer design. Bushings pressed into the arm base are made of graphite-enhanced copper alloy.

2. Comprehensive Configuration: Each long-reach front attachment set includes a six-pin connection structure, four high-pressure hoses, three lubrication pipelines, a linkage mechanism, a bucket cylinder, a bucket, and a full set of seals.

3. Key Advantages:

   • Advanced manufacturing techniques ensure superior quality: plasma cutting, machined edge beveling, robotic welding, post-weld precision boring, and streamlined assembly.

   • Customizable arm solutions tailored to specific working environments and user requirements.

   • Optimized design achieves a bucket rotation angle of up to 163°, significantly expanding digging radius, depth, and maximum reach height.

Your project can run smoothly with the right equipment. When choosing your machinery, consider these factors:

1. Working height: Find out the maximum height of the site you are demolishing. This measurement will help you determine if you need high-reaching equipment.
2. Ground conditions: Before you start working, check the ground conditions with an engineer. The ground’s weight capacity and security will impact which equipment is safe to use on-site.
3. Attachments: Research which attachments will work for your project and ensure you have them readily available.
4. Size: Always make sure you can safely use the attachment within a safe working distance. If you have to extend a crane or excavator’s arm fully, you might need to get a larger version.
When you pay attention to those aspects, you can narrow your search for the right tool.
