The Genie 1278177GT is a genuine OEM Left OPA Weldment, Small, designed for Genie Z-series articulating boom lifts including the Z-40/23N, Z-34/22, and Z-30/20 N. As a factory-sourced structural component, this weldment is manufactured to the exact specifications Genie requires for correct fitment and structural integrity on the platform assembly. Cross-reference part number 1278177GT against your machine's parts manual to confirm compatibility with your specific model and serial range before ordering. Compatible models include the Z-40/23N, Z-40/23N RJ, Z-30/20 N, Z-30/20N RJ, Z-34/22 Bi-Energy, Z-34/22 DC, Z-34/22 N, and Z-34/22 IC.
Key Features
- Genuine OEM Construction — Fabricated to Genie's original weld and material specifications, ensuring the structural geometry of the platform arm assembly is maintained without compromise.
- Direct Structural Replacement — Engineered to mount in the same location and orientation as the original left OPA weldment, allowing a straightforward swap during platform assembly service.
- Broad Z-Series Compatibility — Fits multiple Genie articulating boom lift variants across the Z-30/20 N, Z-34/22, and Z-40/23N families, including RJ and Bi-Energy configurations.
- Platform Arm Integrity — A correctly installed OPA weldment maintains proper platform positioning and articulation through the full range of boom movement; a damaged or worn weldment can compromise platform level and stability.
- Aerial Work Safety Relevance — As a structural element of the operator platform assembly on an articulating boom lift, this component directly supports the safe positioning and support of the work platform at height.
The OPA (Oscillating Platform Assembly) weldment is a fabricated structural bracket that forms part of the mechanism responsible for keeping the operator platform level as the boom articulates through its range of motion. The left-side weldment serves as a mounting and pivot point within this assembly, working alongside the right-side counterpart to distribute load and maintain alignment. When this component is cracked, bent, or otherwise compromised, the platform leveling system can be affected, creating an unsafe working condition for the operator and triggering inspections or out-of-service status for the machine.
