What the purpose of service elevator?

The purpose of a service elevator is to transport goods, equipment, and supplies between different floors of a building, typically in commercial or industrial settings. Service elevators are designed to be larger and more durable than passenger elevators, and are often used by maintenance staff, housekeeping, and delivery personnel to move heavy or bulky items efficiently and safely. They are also used to transport trash, recycling, and other materials that are not suitable for the regular passenger elevators.
