Do you need any qualification certificates for small cranes (non-vehicles) used to lift construction waste or cement sand when decorating high-rise residential buildings?

I am an engineer. If the price is not too expensive, I suggest using the property and reducing the price together with the property. Maybe he just wants to engage in monopoly, but of course you can't guarantee that it won't destroy or pollute the environment of the community at all. Of course, the residential property is too tough, you can also complain. If he wants you to use his lift, you can ask him to show his qualifications and the terms of the community regulations. You have nothing to complain about.
