The safe working load of wire mesh cable trays

The safe working load (SWL) capacity of wire mesh cable trays should meet the requirements in the table below.

1.Under the action of safe working load (SWL), the actual mid-span deviation of each span should not exceed 1/100 of the span; the actual lateral deviation of each span should not exceed 1/20 of the bridge width. During and after the test, the joint parts and connecting parts of the test sample should not be damaged or have visible cracks.

2.The test sample remains in its original shape under the action of 1.7 times the safe working load (SWL) for 30 minutes. The test sample should be able to withstand the load without breaking. Under this load, the bending and deformation of the test sample are allowed.
