The Genie 111090GT is a genuine OEM Wheel Drive with Brake, 57.49:1, designed for Genie S-80 and S-85 telescopic boom lifts and the Z-80/60 articulating boom lift. As a factory-original component, this drive unit is built to the same specification as the part it replaces, ensuring correct torque output, braking performance, and interface geometry for these heavy-duty boom platforms. Cross-reference part number 111090GT against your Genie parts manual to confirm fitment for your specific serial range before ordering.
Key Features
- Factory-Matched Drive Ratio — Built to the exact 57.49:1 gear reduction ratio specified for these boom models, maintaining the correct travel speed and tractive effort Genie engineers designed into the drivetrain.
- Integrated Brake Assembly — The brake is built into the drive unit, so installation replaces the entire wheel-end drive and braking function in a single assembly — no separate brake sourcing or additional adaptation needed.
- Genuine OEM Construction — Manufactured to Genie's original design tolerances for gear mesh, seal integrity, and bearing load rating — critical qualities in a drive unit subjected to continuous load cycling on elevated boom lifts.
- Direct Replacement for S and Z Boom Platforms — Fits the S-80, S-85, and Z-80/60 — large-platform boom lifts that depend on consistent wheel-drive performance to maneuver safely under full load.
- Operational Safety at Height — A worn or failing wheel drive unit on a large boom lift can result in loss of drive, brake fade, or uncontrolled movement on grade. Replacing with this genuine OEM unit restores the full drive and braking capacity the machine was certified with.
The wheel drive with brake is the self-contained unit that transfers hydraulic or electric power to each driven wheel while simultaneously providing the holding brake that prevents the machine from rolling when drive is not engaged. On large boom lifts like the S-80, S-85, and Z-80/60, where the combination of extended platform height and high machine weight places extreme demands on the drive system, the integrity of this component directly affects both mobility and on-grade stability. When a wheel drive unit begins to fail — through internal gear wear, seal leakage, or brake degradation — the machine may exhibit sluggish travel, uneven drive response, or an inability to hold position on sloped surfaces, all of which compromise safe operation at height.
