The Genie 128605GT is a genuine OEM Extension Boom Weldment designed for Z-45/25 and Z-45/25J series articulating boom lifts, including the Z-45/25J DC, Z-45/25J Bi-Energy, and Z-45/25J IC Power variants. Sourced directly through Genie's OEM supply chain, this weldment is the correct structural assembly for these machines — no guesswork, no cross-fitting from a different model. Cross-reference part number 128605GT against your parts manual to confirm suitability for your specific serial range before ordering.
Key Features
- Genuine OEM Structural Integrity — Manufactured to Genie's original engineering specifications, ensuring the weldment meets the same load-bearing and dimensional standards as the part it replaces.
- Direct Bolt-In Replacement — This weldment is engineered to align with existing mounting points on the Z-45/25 boom assembly, allowing straightforward installation without custom fabrication.
- Broad Z-45/25J Variant Coverage — Fits the Z-45/25, Z-45/25J DC, Z-45/25J Bi-Energy, and Z-45/25J IC Power, covering the full range of power configurations in the Z-45/25J family.
- Restores Full Reach Capability — A sound extension boom weldment is essential for the articulating boom to extend and position the platform correctly; a cracked or compromised weldment can limit effective reach and platform control.
- Critical Safety Component — As a primary structural element of the boom extension system, this weldment directly supports platform stability and operator safety at height — replacing a damaged unit with a genuine OEM part maintains the structural integrity the machine was designed around.
The extension boom weldment is the fabricated structural section that forms the extendable portion of the articulating boom arm. It carries the mechanical loads generated when the boom is extended, articulated, and loaded with personnel and equipment, transferring those forces back through the machine's main structure. When a weldment develops cracks, deformation, or corrosion damage, the boom's ability to extend safely and hold position under load is compromised — making timely replacement with a correctly specified OEM part essential to keeping the machine fit for work at height.
