How to avoid hidden dangers when the smart rack is bearing weight? As a manufacturer of smart racks with guardrails, let the editor take you to understand it together.
1. Load-bearing design and selection: avoid risks from the source
Clear load-bearing requirements
Calculate the single-layer and overall load-bearing according to the type of stored goods (such as steel, cartons, liquid containers, etc.).
Example: If each box of goods weighing 50kg is stored, if the smart rack is designed to be stacked in 4 layers, it is necessary to ensure that the single-layer load-bearing is ≥50kg and the overall load-bearing is ≥200kg (including safety factor).
Choose compliant materials and structures
Preferably use high-strength steel (such as Q235B or Q345B) to ensure that the bending and shear strength meet the standards.
Analogy: Ordinary steel such as "chopsticks" are easy to bend, and high-strength steel such as "rebar" can withstand greater pressure.
Structurally select reinforced columns, beams and bottom supports to avoid single-point force.
Consider dynamic load and impact
If frequent forklift handling is involved, the dynamic load factor needs to be increased (usually 1.5-2 times the static load).
Case: A warehouse did not consider the impact of forklifts, resulting in deformation of the columns of the smart frame and overturning of the goods.
2. Installation and use specifications: ensure structural stability
Professional installation and regular inspection
Installed by a professional team to ensure that the bolts are tightened and there are no cracks at the welding points.
Checklist:
Check the verticality of the columns every month (deviation ≤5mm);
Check whether the connection between the beam and the column is loose every quarter;
Inspect the rust on the steel surface every year (repair is required if the rust depth is greater than 1mm).
Even stacking and height limit control
The goods need to be evenly distributed to avoid eccentric loading (such as excessive weight on one side).
Strictly abide by the stacking layer limit (usually 3-5 layers), exceeding the limit will cause instability in the center.
Data: A warehouse exceeded the limit and stacked to 7 layers, causing the bottom smart frame to collapse, and the loss of goods exceeded 100,000 yuan.
Ground flatness and bearing capacity
The smart frame must be placed on a level ground (slope ≤ 1%), otherwise it will easily tilt.
The ground bearing capacity must be ≥ the total weight of the smart frame when fully loaded (e.g. a smart frame fully loaded with 2 tons requires a ground bearing capacity ≥ 2 tons/m2).
