Owners who purchase and install elevators have no relevant professional knowledge and experience, so they can adopt professional subcontracting to ensure the elevator installation is in place, compliant and safe. If the owner has relevant professional knowledge and experience, he can find a credible elevator and installation company, or a material procurement contract to reduce costs.
No matter which way is adopted, you need to pay attention to choosing a regular elevator and installation company and operate in strict accordance with relevant laws and regulations.
