1. load tests shall be ladder side height ( 60,75,100,150,200 ) randomly selected two in the span of provisions .
2. tests should span two Order of the distance from the center , the value of Table 6 allows branch hanging stride value error of ± 38mm .
3. test device should be placed for Charpy , tank level without any constraints at both ends , and no lateral restraint .
4. Dimensions of load test materials , homogeneity should be the same . Load Fractional plus increments of roughly equal amount of load away from the side of the inner wall of not less than 12.5mm , no larger than 25mm . The cable tray should be evenly distributed load on the specimen length and width , arranged longitudinally. The minimum distance between each stack of 10mm, can not be cross- connected across all loads should be placed in the support between . Allow length not more than 915mm of steel sheet cover in support between the bottom of the tank , is not fixed , do not lap , the quality of the steel plate should be added to the load of the total weight of .
5. span (4.5mm ) heavy duty cable tray load determination , in addition to Table 6 applied uniform load needs additional 1000N concentrated load in the middle of .
6. deflection value should be in the vertical direction on both sides of the center of symmetry of the two bearing , measured with a dial indicator , taking the average of the two points as a cable tray rated the cloth under a load deflection value .
It is a very informative and useful post thanks it is good material to read this post increases my knowledge....
