24m Excavator Long Reach Boom and Arm for Cater-Piller Cat385

This 24m long reach boom and arm is engineered for the Cater-Piller Cat385 excavator, extending working range for deep excavation, dredging, and large-scale construction projects. Manufactured since 2006 with over a decade of experience in designing and customizing long reach booms for all major excavator brands, each unit is built to the exact installation dimensions of the target machine.

The complete attachment is supplied with a full hydraulic and lubrication pipe system, bucket, bucket cylinder, linkage, pins, and hoses, ready for efficient installation and reliable field performance.

• Custom fitment: Installation dimensions for the CAT390D are fully documented, allowing the long boom to be customized precisely for your CAT390D excavator.
• High-strength materials: Main structure uses Q345B combined with Q690D; top and bottom cover plates are Q690D, remaining areas are Q345B, and pins are made of 42CrMo4.
• Certified welding process: Manual protective-gas welding with an 80% Argon / 20% CO2 mix — the recognized gold standard for protective gas welding.
• Edge milling before welding: A large edge milling machine prepares the sheet edges so welds penetrate into the steel sheet interior, improving structural performance.
• Post-weld precision machining: All base, joint, and main structures are adjusted on a boring machine after welding to prevent welding stress from causing excessive tolerance.
• Complete hydraulic package: Lubricant pipe system, hydraulic system, bucket, bucket cylinder, linkage, pins, and hoses are prepared and supplied with the long boom.
• Cost-saving stick cylinder option: The original stick cylinder can be reused to reduce cost; a new stick cylinder can also be supplied on request.
• Auxiliary pipe lines: One or two extra auxiliary pipe line kits can be prepared for the long reach boom attachment when required.
• Lead time and warranty: Manufacturing time is approximately 25 days, with a 6-month warranty after installation.
• Maintenance support: A complete parts list is supplied with each long reach boom for easy maintenance and after-sales service.

• Dredging of rivers and sea areas
• All types of construction projects requiring a long reach excavator
