The Genie 89166-SGT Extension Boom #2 Weldment is a genuine OEM structural component designed for Genie S-100, S-105, S-120, and S-125 telescopic boom lifts. As a direct OEM replacement, this weldment is manufactured to the same specifications as the original, ensuring it integrates seamlessly into the boom assembly without modification. Cross-reference part number 89166-SGT against your Genie parts manual to confirm fitment before ordering. If you're restoring a boom that's experienced structural wear or damage to the extension section, this weldment is the correct replacement to bring that machine back to full working order.
Key Features
- Structural-Grade OEM Construction — Fabricated to Genie's original weld and material standards, this weldment maintains the structural rigidity and load-path integrity the extension boom section demands.
- Direct OEM Replacement — Engineered to drop into the existing boom assembly on compatible S-series telescopic booms, aligning with factory mounting points and hardware interfaces.
- Fits Genie S-Series Telescopic Booms — Compatible with the S-100, S-105, S-120, and S-125 large-platform telescopic boom lifts — some of the tallest in the Genie S-series range.
- Restores Full Extension Capability — A damaged or cracked extension boom weldment compromises the machine's ability to reach and hold platform height safely. This replacement restores the structural continuity required for full boom operation.
- Critical Safety Component — The extension boom is a load-bearing structural element on aerial work platforms. Replacing a compromised weldment with a genuine OEM part is essential to maintaining the machine's rated capacity and platform stability.
The Extension Boom #2 Weldment is a core structural section of the telescopic boom assembly, forming part of the extending framework that allows the boom to reach its full working height. As the boom extends, this weldment carries both the mechanical load of the structure above it and the dynamic forces generated by platform movement and load. When this section is cracked, deformed, or otherwise compromised — whether from impact, fatigue, or corrosion — the entire boom's structural integrity is at risk, and the machine should be taken out of service until the component is replaced. Fitting a genuine OEM weldment ensures the repaired boom meets the original engineering tolerances required for safe, rated operation.
