Workers fall from the elevator and get injured. Who is responsible for the property management company, the elevator company and the owner?

It depends on which company the worker belongs to and where he works. If it is an elevator company, it is the responsibility of the elevator company, and the property is only responsible for supervision. If it's a property, it depends on how he got into the elevator. Elevator keys, whether triangle keys or computer room keys, must be managed by special personnel. Triangular keys must also be used by personnel with post operation certificates. For example, the elevator company does not need to be responsible without knowing it, and the property is fully responsible.
