Key Features
- Direct OEM Replacement — This plate installs in place of the original with no rework or adaptation, preserving the structural alignment of the hinge assembly it supports.
- Confirmed Fitment — Fits Genie S-60, S-65, S-65 XC, and S-85 XC telescopic boom lifts, covering a wide range of the S-series fleet.
- Structural Integrity — A sound hinge support plate keeps the hinge assembly correctly positioned and load-bearing; a cracked or deformed plate compromises the integrity of the connection it anchors.
- Operational Safety — On aerial boom lifts, structural hinge components are load-path critical. Replacing a worn or damaged plate with the correct OEM part helps maintain the machine's structural integrity during operation.
A hinge support plate provides the structural backing that holds a hinge assembly in position under load. On telescopic boom lifts, hinge points transfer forces between major structural sections of the machine, and the support plate distributes those forces across the mounting area rather than concentrating stress at a single point. When a hinge support plate cracks, bends, or corrodes through, the hinge can shift out of alignment, accelerating wear on adjacent components and potentially compromising the structural connection it anchors. Replacing the plate with the correct OEM part restores the designed load path and keeps the assembly operating as intended.
