The Genie 50247GT is a genuine OEM Extension Cable Sheave built for Genie S and SX series telescopic boom lifts, including the S-100HD, S-120HD, and SX-125 XC. As an authentic Genie replacement part, it is manufactured to the same standards as the original component, ensuring a correct fit without modification. Cross-reference part number 50247GT against your machine's parts manual before ordering to confirm it is the right sheave for your unit and serial number range.
Key Features
- Genuine OEM Precision — Manufactured to original Genie specifications, with the correct groove profile and bore dimensions to maintain proper cable tracking and seating.
- Direct-Fit Replacement — Designed to drop into the existing sheave mount on the extension assembly with no rework required to the surrounding hardware.
- Broad S and SX Series Coverage — Fits the S-100HD, S-120HD, and SX-125 XC telescopic boom lifts, making this the correct OEM choice for high-reach Genie straight-boom platforms.
- Smooth Cable Operation — A sound sheave keeps the extension cable running true in its groove; a worn or cracked sheave causes uneven cable wear, fraying, and unreliable boom extension.
- Operational Safety — On aerial boom lifts operating at extreme heights, correct cable guidance through the sheave is critical to controlled, predictable boom movement — making like-for-like OEM replacement the right call.
A sheave is a grooved pulley wheel that guides a cable as it moves through the boom extension system. It keeps the cable aligned under load, distributing tension evenly and preventing the cable from slipping off its path or wearing against adjacent metal surfaces. When a sheave cracks, chips, or wears smooth in its groove, it allows the cable to wander or chafe, which accelerates cable fatigue and can lead to inconsistent boom extension or retraction. Replacing a worn sheave with the correct OEM part restores proper cable guidance and protects both the cable and the surrounding structure from accelerated wear.
