OEM suspension / rebuild kit for 100‑ton sectional scale systems
Supports 400,000 lb (400 k lb) total capacity
Fits sectional lengths: 50 ft (Model 6820), 56 ft (6821), 60 ft (6822), 66 ft (6823), 72 ft (6824)
Compatible with Type S‑20‑100 lever geometry and Main Lever Casting #SM8E
Includes suspension arms, pivots, trunnion supports, linkage hardware, bearings, and mounting components
Restores mechanical alignment, reduces drift, and extends scale service life
The Fairbanks Kit F‑491‑RK is a factory replacement suspension and linkage kit engineered for high‑capacity, sectional lever scale systems. Built for 100‑ton sectional use—equivalent to 400,000 lb total capacity—this kit accommodates scale spans from 50 ft to 72 ft (Models 6820 through 6824) using Type S‑20‑100 straight lever mechanics with Main Lever Casting #SM8E.
Under heavy load operations, suspension arms, pivots, trunnion supports, bearings, and linkage elements undergo fatigue, wear, or deformation. Such degradation leads to misalignment, increased friction, and weighing inconsistency. Kit F‑491‑RK provides the matched OEM components to rebuild suspension geometry, reestablish rigid load paths, and ensure accurate measurement over full span lengths.
Using this kit helps maintain calibration integrity, reduce maintenance downtime, and preserve scale performance, especially for large lever systems where mechanical tolerances are critical. Because it matches the original design specifications, installation is more predictable and re‑calibration is more stable.
