Used Boom

Excavator Boom: The Key Component of Your Excavator

The boom is the reinforced steel structure that pivots on the excavator’s superstructure and supports the stick at its end. During operation, it absorbs bending and twisting stresses related to digging, lifting, and rotation cycles. A boom showing deformations, cracks along weld seams, or enlarged pivot holes directly impacts work precision and operator safety. Replacing your boom with a selected and inspected used spare part allows you to regain original performance without investing in new equipment.

To complement your setup, Codimatra also offers used boom cylinders inspected in our workshop and directly compatible with leading market brands.

Types of Booms Available at Codimatra

Our selection covers all common configurations encountered in earthmoving, demolition, and special work sites:

• One-piece booms for mini and micro excavators from 1 to 5 tons, ideal for confined spaces.
• Two-piece booms (dual-section booms) for medium excavators from 6 to 20 tons, allowing reach adjustment according to site needs.
• Long-reach booms for heavy excavators of 20 tons and above, designed for deep digging and intensive earthmoving.
• Boons for wheeled excavators, with specific geometry adapted to their superstructures.
• Compatibility with major brands: Caterpillar, Komatsu, Volvo, Liebherr, Hyundai, JCB, Case, Hitachi, and more.

How to Choose a Replacement Boom for Your Excavator?

Several criteria determine a used boom’s compatibility with your machine. The exact make and model condition assembly dimensions: diameter and spacing of pivot pins, structure geometry, hydraulic mounting points for used bucket cylinders and stick. The effective length of the boom defines working reach and digging depth: the right sizing is critical according to your type of work (trenching, bulk earthmoving, demolition).

Manufacture year and series also play a role, as some manufacturers have updated pivot dimensions across generations. If in doubt, our technical advisors compare your machine’s reference with our stock to guide you toward the best-suited part.

For earthmoving equipment, also consider checking the condition of your used digging bucket: bucket and boom wear often progress together on heavily used machines.

Inspection and Selection of Booms in Codimatra’s Workshop

Every used boom added to our inventory undergoes a series of verifications in our workshop before being offered for sale:

• Visual weld inspection: checking weld seams along the entire structure length for cracks or non-compliant repairs.
• Pivot bore verification: measuring play at upper and lower rotation axes to ensure assembly tolerances are met.
• Hydraulic fittings examination: assessing cylinder mounts, fittings, and integrated hose routes.
• Geometric checks: detecting permanent deformations, bends, or twists affecting boom alignment.
• Cleaning and packaging before shipment to facilitate onsite reception and assembly.

Our parts come from selected machines, dismantled and processed in our Castelculier workshop. This meticulous selection has been the foundation of our expertise for over 40 years serving construction professionals.
