How do I know if my boom needs replacement?

Several signs indicate that a boom must be replaced: visible cracks on weld seams, excessive play on upper or lower pivot pins, permanent structural deformation (bending, twisting), or impact marks that have weakened the steel. A damaged boom compromises work accuracy and may pose a safety risk to the operator. If uncertain, our technical advisors assist in assessing the part’s condition before any decision.

Is it possible to fit a boom from a different brand on my excavator?

Technically, it is possible in some cases, but this requires thorough verification of assembly dimensions: pivot pin diameters, spacing, clevis height, and hydraulic mounting points. Each manufacturer defines its own tolerances, and dimensional incompatibility may make installation impossible or unsafe. At Codimatra, our advisors analyze your machine’s dimensions to identify compatible booms, whether original or from an equivalent brand.

Do you offer booms for mini excavators?

Yes. Our selection includes one-piece booms suited for mini and micro excavators from 1 to 5 tons, used in confined spaces, indoors, or urban areas. As with larger excavators, every mini excavator boom is workshop inspected: welds, pivot pins, and structure geometry are checked before shipment.

Do you deliver used booms internationally?

Yes, Codimatra ships spare parts both within France and internationally. Due to their size and weight, booms are transported using carriers specialized in construction equipment. Our advisors provide delivery times and shipping details based on your destination country when you place your order.

What is the difference between a boom and a stick on an excavator?

The boom is the first articulated arm: it connects the excavator’s rotating superstructure to the stick. The stick (or dipper arm) is the second segment that pivots at the boom’s end and carries the bucket. These two parts work together but are mechanically distinct. At Codimatra, booms and sticks are cataloged separately in our stock of excavator equipment parts.
