The Genie 128304GT is a genuine OEM Extension Boom Weldment built for Z-45/25J and Z-51/30J articulating boom lifts. As a factory-original structural component, it is manufactured to the same specifications as the part it replaces, ensuring the correct geometry, load ratings, and attachment points for the jib section of the boom. This weldment is confirmed to fit the Z-45/25J DC, Z-45/25J Bi-Energy, Z-45/25J IC Power, Z-45/25 IC, Z-51/30J, and Z-45/25J IC variants.
Key Features
- Genuine OEM Structural Integrity — Fabricated to Genie's original weldment specifications, maintaining the correct material grade, weld quality, and dimensional tolerances required for a structural boom component.
- Direct Bolt-In Replacement — Engineered to match the original mounting points and attachment interfaces on Z-45/25J and Z-51/30J boom assemblies, so installation proceeds without rework or modification.
- Broad Z-Series Fitment — Compatible with multiple Z-45/25J configurations including DC, Bi-Energy, IC Power, and IC variants, as well as the Z-51/30J, covering a wide range of Genie articulating boom lift fleets.
- Restores Full Boom Extension Capability — A damaged or cracked extension boom weldment compromises the jib's reach and rigidity. Replacing it with this OEM part restores the machine's designed working envelope and structural performance.
- Operational Safety — The extension boom weldment is a primary load-bearing structure on an aerial lift. Using a genuine Genie replacement ensures the component meets the structural requirements that protect operators working at height.
The extension boom weldment is the fabricated structural tube and bracket assembly that forms the jib section of the articulating boom, allowing the machine to reach beyond the main boom's arc and extend the platform's working position. On Z-series articulating lifts, this component carries both the weight of the platform and the dynamic loads placed on it during operation. A weldment that is cracked, bent, or otherwise compromised reduces structural rigidity, limits reach, and creates a hazardous working condition. Replacing a damaged unit with part number 128304GT restores the boom to its intended geometry and load-bearing capacity.
