What factors are related to the load-bearing capacity of fluent shelves? 1. Core component specifications of the cargo lane: roller material (plastic rollers have low load-bearing capacity, metal rollers have high load-bearing capacity), roller diameter and spacing (large diameter+dense spacing are more durable), and layer thickness (thicker steel plates have stronger load-bearing capacity than thin steel plates), which directly determine the upper limit of single cargo lane load-bearing capacity. 2. Shelf structural strength: column material and cross-sectional dimensions (thicker steel columns have higher load-bearing capacity than lightweight columns), beam specifications (load-bearing beams need to match the total weight of the cargo lane), and connection method between the cargo lane and columns (reinforced connectors can improve overall load-bearing stability). 3. Distribution and weight of goods: Whether the goods in a single aisle are evenly placed (concentrated overweight can easily damage the rollers), whether the total weight of a single aisle exceeds the design value, and the number of single-layer shelf cargo lanes (the more cargo lanes, the more the single-layer overall load-bearing needs to be balanced to avoid local overload).
