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.
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.
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.
Ideal Applications: Suitable for subway projects, river dredging, reservoir maintenance, and various other engineering operations requiring extended reach and precision.

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.
