When the ladder bears the weight or begins to bear the weight, the pressure borne by the ladder is transmitted to the bearing sensor, the bearing sensor transmits a trigger signal to the weighing integrated circuit, the weighing integrated circuit calculates the pressure, and when the pressure exceeds the bearing capacity of the ladder, the warning device gives a prompt (of course, the warning can also give a prompt about any bearing state in the use of the ladder).

The aim of the invention can also be solved by the following technical measures:

as a more specific scheme, the load-bearing sensor is arranged at the foot part of the ladder; the ladder comprises a ladder body and anti-skidding foot sleeves, wherein the anti-skidding foot sleeves are arranged at the bottoms of ladder feet of the ladder body, and the anti-skidding foot sleeves and the ladder feet form the feet. Because the foot supports the ladder, when the load-bearing sensor is arranged at the foot of the ladder, the weight of the ladder is increased during the use process, namely the load-bearing sensor can acquire data and feed the data back to the weighing integrated circuit.

As a further proposal, the load-bearing sensor is arranged between the ladder foot and the anti-skid foot sleeve; or the bearing sensor is arranged on the bottom surface of the anti-skidding foot sleeve.
