The Genie 232903GT is a genuine OEM RT B4 Extension Sheave Mount Weldment designed for Genie SX-150 and SX-180 super-boom telescopic lifts. As a direct OEM replacement sourced through the Genie parts program, this weldment is manufactured to the same specifications as the original component installed at the factory. Cross-reference 232903GT against your parts manual to confirm fitment before ordering. Buyers running SX-series super-boom fleets will find this a straightforward, like-for-like swap that restores the boom extension system to proper working order.
Key Features
- Genuine OEM Construction — Manufactured to the original Genie engineering specification for the RT B4 Extension Sheave Mount position, ensuring correct weld geometry and structural integrity under boom-extension loads.
- Direct Bolt-On Replacement — Engineered to match the original mounting points and sheave interface, so this weldment installs in place of the worn or damaged component without reworking surrounding structure.
- Confirmed SX Super-Boom Fitment — Fits Genie SX-150 and SX-180 super-boom telescopic lifts; cross-reference part number 232903GT with your serial-number parts breakdown to verify your specific machine configuration.
- Structural Integrity for the Boom Extension System — The sheave mount weldment anchors the cable-routing sheave that guides the extension mechanism. A cracked, bent, or missing weldment disrupts cable alignment and can prevent the boom from extending or retracting correctly.
- Safety-Critical Structural Component — On super-boom lifts operating at extreme working heights, maintaining the structural soundness of every boom-system weldment is essential to safe, predictable boom operation. Replacing a damaged mount with a genuine OEM part preserves the designed load path through the boom assembly.
The RT B4 Extension Sheave Mount Weldment is a structural bracket welded into the boom assembly that carries and positions a cable-routing sheave — a grooved wheel that guides the wire rope or cable responsible for driving the telescoping extension of the boom. By holding the sheave in precise alignment, this weldment ensures the extension cable tracks correctly under load, allowing the boom to extend and retract smoothly and predictably. When this mount is damaged, cracked, or misaligned, the cable can jump its groove or bind, causing erratic boom travel or a complete loss of extension function — a serious operational concern on the SX-150 and SX-180 at the working heights these machines are built to reach.
