The main parameters of the elevator refer to the rated load and rated speed.
The rated load Q (kg) is the load on which the elevator is built or the load that the seller guarantees to operate normally.
The rated speed v (m/s) is the speed of the car on which the elevator is built and which is guaranteed by the seller to move normally.
With the massive construction of high-rise buildings, people have to deal with elevators whether they are commuting, shopping, visiting a doctor or visiting friends, or living at home. The number of elevators is increasing and the frequency of use is getting higher and higher. The safety of elevators has attracted more and more attention.
