The Genie 74334GT is a genuine OEM Upper Secondary Boom Assembly designed for Z-30/20N and Z-30/20N RJ articulating boom lifts. Sourced directly from Genie, this assembly matches the original component specification, ensuring a direct, drop-in replacement with no guesswork on fit or form. Cross-reference part number 74334GT against your parts manual to confirm this is the correct assembly for your machine's serial range before ordering.
Key Features
- Genuine OEM Structural Integrity — Built to the same tolerances and material grades as the original boom assembly, preserving the structural load ratings your articulating boom was engineered around.
- Direct-Fit Replacement — Engineered to align with existing mounting points, pivot hardware, and cylinder attachment brackets on the Z-30/20N and Z-30/20N RJ, allowing straightforward installation by a qualified technician.
- Confirmed Fitment for Z-30/20N Variants — Fits both the standard Z-30/20N and the Z-30/20N RJ configuration, covering the primary articulating boom models in this platform class.
- Restored Boom Function — A damaged or compromised secondary boom section affects reach, articulation range, and load path. Replacing it with this assembly restores full range of motion and the machine's intended working envelope.
- Critical Safety Component — The secondary boom assembly is a primary structural element in the lift's elevation system. Using a genuine OEM replacement ensures the component meets the safety-critical performance requirements for aerial work at height.
The secondary boom assembly is the intermediate structural section of an articulating boom lift, connecting the primary (lower) boom to the upper jib and platform. It carries the combined load of the platform, operator, and materials while transmitting force from the lift and extension cylinders that control reach and elevation. When this assembly is cracked, bent, or otherwise compromised, the machine loses the structural integrity needed for safe operation at height — articulation becomes unpredictable, cylinder alignment is affected, and the platform can no longer be trusted to hold position. Replacing the assembly with the correct OEM component restores the full range of motion, proper cylinder geometry, and the load-bearing capacity the machine was certified to deliver.
