The Multiquip A400333700 Upper Pulley Pin is a genuine OEM component designed for GBX balloon light systems and towable towers, including the GBX24S, GBX24B, GBX12S, GBX12SK, and GBX24BK. As a direct Multiquip OEM part, the A400333700 is manufactured to the same specifications as the original, ensuring a correct fit within the pulley assembly. This pin is a critical structural component of the mast raising system, and sourcing a genuine replacement keeps your GBX unit operating as intended.
Key Features
- Genuine OEM Construction: — Manufactured to Multiquip's original dimensional tolerances, ensuring the pin seats and retains correctly within the upper pulley assembly without slop or misalignment.
- Direct Drop-In Replacement: — Engineered to install exactly as the original, matching bore diameter and length for the upper pulley position on GBX series mast systems.
- Broad GBX Series Compatibility: — Fits GBX12S, GBX12SK, GBX24S, GBX24B, and GBX24BK balloon light and towable tower models.
- Mast System Integrity: — A correctly fitted upper pulley pin keeps the cable or line tracking true during mast raise and lower cycles — a worn or missing pin can cause cable derailment and prevent full mast deployment.
- Operational Safety: — The upper pulley pin is a load-bearing retention component in the mast lift mechanism; using a correctly rated OEM pin is essential for safe mast operation at height.
The upper pulley pin is a retention and alignment component located at the top of the GBX mast assembly. It holds the pulley in position so that the lift cable tracks correctly as the mast is raised or lowered, transferring load smoothly through the pulley during operation. When this pin wears, bends, or goes missing, the pulley can shift or separate from its mount, causing cable derailment, uneven mast travel, or an inability to fully extend the light tower to working height.
