The bearing capacity of the 3 inspection:

In order to prevent poor quality ladders in the inspection capacity when hurt us, we should first look at the mark what is the maximum capacity, the endurance and weight matched when applicable, to test., but not all of a sudden increase in affordable, need to add some weight to the test, in a ladder GB GB 12142-2007 load can be divided into four files, respectively 90KG, 100KG, 110KG, 135KG, ladder safety load qualified should be more than 2.5 times mark.
