The Genie 99640GT is a genuine OEM Extension Weldment designed for TZ-50/30 and TZ-50 trailer-mounted articulating boom lifts. As a factory-sourced structural component, this weldment meets the same specifications as the original part fitted at the time of manufacture, ensuring correct integration with the boom's extension system. Cross-reference part number 99640GT against your parts manual to confirm this is the correct component for your machine's configuration before ordering.
Key Features
- Genuine OEM Structural Integrity — Manufactured to Genie's original design tolerances, this weldment maintains the structural rigidity and dimensional accuracy required for correct boom extension function.
- Direct Replacement Fit — This component installs in place of the original weldment on TZ-50/30 and TZ-50 booms, aligning with existing mounting points without modification to the boom assembly.
- Confirmed Fitment for TZ-Series Trailer Booms — Verified for the TZ-50/30 and TZ-50 trailer-mounted articulating boom lifts, giving you confidence you are ordering the right part for your machine.
- Restored Boom Extension Performance — A sound extension weldment is critical to smooth, controlled boom reach. A cracked, bent, or worn weldment can compromise range of motion and the overall stability of the boom assembly.
- Safety-Critical Structural Component — On aerial boom lifts, structural weldments are load-bearing elements that directly affect platform stability at height. Using a genuine OEM replacement ensures this part meets the original engineering requirements for safe operation.
An extension weldment is a fabricated structural assembly that forms part of the boom's reach mechanism, connecting and supporting sections of the boom arm as it extends outward. On trailer-mounted articulating booms like the TZ-50/30 and TZ-50, this component bears significant dynamic loads during extension and articulation, making its structural condition essential to safe and predictable machine operation. When a weldment develops cracks, deformation, or corrosion damage, it can affect boom alignment, restrict extension travel, and compromise the load path through the arm — making timely replacement with a correct OEM part the right call.
