The Genie 20780GT is a genuine OEM 2 Speed Trombetta Solenoid built for Genie telescopic and articulating boom lifts, including the S-60 J, Z-34/22 Bi-Energy, Z-34/22 IC, Z-34 IC, and Z-45/22 MP. As a factory-sourced component, this solenoid meets the same specifications as the part it replaces, ensuring a direct, reliable fit. Cross-reference part number 20780GT against your machine's parts manual to confirm it is the correct item for your serial number and configuration. Ordering the right OEM part the first time keeps your machine back in service without unnecessary delays.
Key Features
- Genuine OEM Quality — Sourced directly from Genie, this solenoid is built to the same dimensional and electrical tolerances as the original, ensuring consistent switching performance and longevity.
- Direct-Fit Replacement — Designed to install in the same location as the original component with no rework or adaptation required to the mounting or wiring.
- Broad Boom Lift Compatibility — Fits Genie S-series telescopic booms and Z-series articulating booms, including the S-60 J, Z-34/22 Bi-Energy, Z-34/22 IC, Z-34 IC, and Z-45/22 MP.
- Two-Speed Function Restored — A failed or sluggish solenoid can prevent the machine from shifting between drive speeds. Replacing it with a correct OEM unit restores proper two-speed operation so the machine performs as intended.
- Operational Safety — On aerial boom lifts, reliable speed-control function is essential to safe machine operation. Using the correct OEM solenoid maintains the electrical and mechanical integrity the original design requires.
A solenoid is an electromechanical switch that uses an electrical signal to move a plunger or actuate a valve, enabling a mechanical or fluid-control action within the machine. On two-speed drive systems, the solenoid responds to operator input to engage or disengage the high-speed drive mode. When the solenoid wears out or fails, the machine may become stuck in a single speed, respond sluggishly, or fail to shift altogether — limiting productivity and potentially creating unsafe operating conditions. Replacing a faulty solenoid with a correct OEM unit like this part restores proper electrical switching and full two-speed functionality.
