Technical Excellence & Physics Engineering Mechanics: Brake Rollers, Incline Angles & Separators
The fundamental difference between a mediocre gravity rack and a high-performance DEXION RACKING dynamic storage solution lies in precision mechanical engineering and metallurgic consistency.
Gravity-driven pallet storage operates under continuous kinetic forces. When a 1,200 kg pallet begins its transit along a 15-meter lane, uncontrolled momentum represents a catastrophic collision hazard to warehouse personnel and goods. DEXION RACKING engineers overcome this via triple-tier safety mechanisms:
1. Speed Controller Brake Rollers: Centrifugal internal braking modules engage automatically when speed exceeds 0.25 m/s. As the rotational velocity increases, centrifugal weights force internal brake shoes against the drum wall, maintaining a steady, whisper-quiet glide irrespective of pallet weight variances.
2. Load Separation Dampening: To protect forklift operators during unloading, our patented mechanical end-stop separators physically disconnect line pressure from trailing pallets. The front pallet rests entirely free; once extracted by the forklift truck, a floor latch mechanism releases the subsequent pallet to advance safely.
3. Steel Structural Deflection Limits: Sized according to strict EN 15512 calculation principles, our cold-formed high-tensile uprights and track support cross-beams maintain deflection limits below L/500 under full static and kinetic impact loading conditions, ensuring roller tracks never bind or jam over decades of continuous shifts.
