The Genie 99129GT is a genuine OEM Pin Mount Backing Plate built for the TZ-34/20 trailer-mounted articulating boom lift. As a factory-original component, it is manufactured to the same specifications as the part it replaces, ensuring a correct, consistent fit at the pin mount location. DHS Equipment supplies this part direct, so you can source the right component with confidence and get your machine back in service.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original dimensional and material standards, delivering the same fit and integrity as the part it replaces.
- Exact Drop-In Replacement — Engineered specifically for the TZ-34/20 pin mount location, with no rework or adaptation needed at installation.
- TZ-34/20 Fitment Confirmed — Verified for the TZ-34/20 trailer-mounted articulating boom lift, so you can order with confidence that this is the correct part for your machine.
- Structural Backing Integrity — A correctly fitted backing plate distributes load evenly at the pin mount point; a worn or missing plate can allow movement, accelerating wear on surrounding components.
- Boom Structural Safety — At pin mount locations on aerial boom lifts, backing plate condition directly affects the mechanical integrity of the joint — using the correct OEM part supports safe, stable operation.
A pin mount backing plate sits behind a pin attachment point on the boom structure, providing a reinforced bearing surface that distributes clamping and shear loads across a wider area. Without it, concentrated stress at the mount can cause the surrounding material to deform or wear prematurely, leading to loose or misaligned pin joints. Replacing a damaged or worn backing plate with part number 99129GT restores the structural integrity of the mount and helps prevent progressive wear to adjacent components on the TZ-34/20.
