Used Long Reach Excavator Booms for Sale Guide

Long reach excavator booms remain essential for contractors handling demolition, dredging, and other jobs requiring work at a distance. When shopping for used long reach booms, understanding how to evaluate condition, compatibility, and return on investment is critical. This article walks through the key considerations to help you buy wisely.

Purpose and Value of Long Reach Booms

Long reach booms extend a machine’s reach by 20–55 feet beyond the standard configuration, enabling deep digging, high demolition, or slope work without moving the base machine. Used booms are a cost-effective option for projects with intermittent need for extended reach, avoiding the higher capital outlay of a dedicated machine. Make sure the specific boom length fits your job profile, as longer booms increase stress and require correspondingly heavier machines.

Inspecting Condition

A thorough inspection separates reliable used booms from risky ones. Start with the welds and structural members: look for cracks, previous repairs, or distortion, especially at pin areas and around the boom foot. Hydraulic cylinder cradles, hose routing points, and pins should show even wear rather than gouges or scoring. Ask for the boom’s maintenance history and any nondestructive testing results. Check for straightness by comparing the boom’s profile to manufacturer specs—warping can indicate past overloads.

Compatibility Checks

Used booms are not universally interchangeable. Verify pin dimensions, hydraulic pressure requirements, and attachment geometry with your excavator’s OEM specs. Conservative operators confirm that the boom’s mass falls within the excavator’s lift capacity at the desired reach; exceeding those limits risks tipping or structural failure. If the boom includes a quick coupler plate or custom brackets, ensure those match or can be adapted without compromising safety.

Hydraulics and Cylinders

Hydraulic lines and cylinders typically wear faster than the boom steel, so inspect seals, rods, and fittings carefully. Look for consistent rod finish with no pitting, since corrosion accelerates seal failure. If a boom comes with cylinders, verify that their bore/rod size and stroke length match the boom design. For cylinders sold separately, check the serial numbers or part references to confirm they are intended for that boom.

Seller Credibility and Documentation

Buy from reputable dealers or rental houses that can verify usage hours, previous inspections, and refurbishments. Request a bill of sale or certificate showing ownership transfer to limit liability. If possible, review past work orders or inspection reports. Dealers that offer reconditioning or warranty support add peace of mind, especially for booms that have been inactive or stored outdoors.

Pricing Considerations

Prices vary widely based on length, fitment, condition, and brand. As a benchmark, compare similar length booms from EC/Hitachi/Cat/Kobelco on auction sites or heavy equipment marketplaces. Factor in refurbishment costs you might need to perform after purchase—repainting, bearing replacement, or hydraulic hose renewal. The total investment should be lower than buying new plus freight, yet high enough to ensure the seller has maintained it properly; deep discounts often mask deferred maintenance.

Transport and Installation

Long reach booms are large, so plan for transportation. Obtain a liftplan, confirm trailer dimensions, and ensure legal permits for oversized loads. When installing, use a crane or a second excavator with sufficient capacity. Tighten linkage bolts to OEM torque specs and bleed any hydraulic circuits before putting the boom back into service. A test run under no-load conditions can reveal binding or leaks before full deployment.

Conclusion

A well-selected used long reach excavator boom delivers big savings while expanding your fleet’s versatility. Focus on structural integrity, hydraulic health, and strict compatibility with your base machine. Documented history and dealer backing mitigate risk, and factoring in refurbishment plus transport helps you compare total cost. With careful evaluation, a used long reach boom becomes a valuable tool for demanding reach applications.
