The Genie 77797GT is a genuine OEM Sensor Mount Weldment designed for Genie S and SX series telescopic boom lifts and Z and ZX series articulating boom lifts. As a direct OEM replacement sourced through DHS Equipment, this weldment matches the original mounting geometry and hardware interfaces specified for these machines — ensuring the sensor installs exactly as it did from the factory. Compatible across a broad range of Genie booms including the S-60 XC, S-85, Z-45/25J Bi-Energy, Z-62/40, Z-135/70, and ZX-135/70, among many others. Cross-reference part number 77797GT against your machine's parts manual to confirm fitment before ordering.
Key Features
- Genuine OEM Construction — Fabricated to Genie's original weldment specification, preserving the structural integrity and mounting accuracy that sensor positioning depends on.
- Correct Mounting Geometry — Machined and welded to match the original bracket profile, so the sensor aligns to its intended orientation without shimming or re-drilling.
- Broad Boom Compatibility — Fits a wide range of Genie S, SX, Z, and ZX series boom lifts, including XC, TRAX, HF, HC, DC, FE Hybrid, Bi-Energy, and IC Power variants.
- Sensor Accuracy Restored — A damaged or deformed mount causes sensor misreading or false fault codes; replacing this weldment restores correct sensor positioning and signal reliability.
- Safety-Critical Function — On aerial boom lifts, sensors supported by this mount contribute to platform control and load-monitoring systems — correct installation is essential to safe machine operation.
The Sensor Mount Weldment is a structural bracket assembly that holds a position or angle sensor at a fixed, precise location on the boom structure. Sensors mounted to this weldment feed real-time data — such as boom angle, platform position, or load state — to the machine's control system, which uses that information to regulate movement and enforce operating limits. When the weldment is bent, cracked, or corroded, the sensor can shift out of alignment, producing inaccurate readings that trigger fault codes, restrict machine function, or — in a worst case — allow the control system to operate on false data. Replacing a compromised mount with the correct OEM weldment restores the sensor to its specified position and returns the boom's control system to normal, reliable operation.
