The Genie 56.0021.0155GT is a genuine OEM Boom Control Unit designed for the GTH-2506 IIIA and GTH-2506 IIIB telehandlers. Sourced directly from Genie, this unit delivers the exact electrical and hydraulic control interface the machine was engineered around, ensuring proper boom operation from day one. The GTH-2506 in both IIIA and IIIB engine-tier configurations is confirmed compatible, so you can order with confidence knowing this component matches your machine's requirements. When the original control unit fails, restoring full boom function quickly is critical — this is the part that gets your telehandler back to work.
Key Features
- Genuine OEM Control Precision — Built to the exact electrical and signal specifications Genie set for the GTH-2506 platform, ensuring accurate boom response and system communication.
- Direct Drop-In Replacement — Engineered to connect to the existing wiring harness and mounting points on the GTH-2506 without modification or adaptation work.
- Confirmed Fitment for GTH-2506 IIIA and IIIB — Verified for both engine-tier variants of the GTH-2506 telehandler, covering the full production scope of this model.
- Restores Full Boom Operability — A failed or malfunctioning boom control unit can render the telehandler's boom inoperable; replacing it with the correct OEM unit returns the machine to full rated function.
- Operational Safety Integrity — Boom control units govern critical movement functions on aerial and material-handling equipment; using a genuine OEM replacement maintains the safety logic and response behavior the machine was designed and certified around.
The Boom Control Unit is the electronic command hub that governs boom movement on the GTH-2506 telehandler. It processes operator inputs and translates them into precise hydraulic and mechanical responses, controlling how the boom extends, retracts, and angles during material-handling operations. When this unit degrades or fails, operators may experience erratic boom movement, unresponsive controls, or a complete loss of boom function — any of which takes the machine out of productive service and can create unsafe working conditions.
