3. Controls and Operation:

- Freight elevators often have manual controls, allowing the operator to control the movement of the elevator and open/close the doors manually. This is useful for loading and unloading goods.
- Passenger elevators usually have automatic controls, with buttons for selecting floors and automatic door operation. They are designed for easy and convenient use by passengers.

4. Safety Features:
- Freight elevators are equipped with additional safety features to handle the transportation of heavy loads. These may include reinforced floors, stronger doors, and special mechanisms to prevent the elevator from moving if the doors are not closed properly.
- Passenger elevators also have safety features but are more focused on passenger comfort and convenience. They may include emergency stop buttons, alarm systems, and smooth acceleration and deceleration to ensure a comfortable ride.

5. Building Codes and Regulations:
- Freight elevators are subject to different building codes and regulations compared to passenger elevators. These codes specify requirements for weight capacity, door size, and other safety features based on the intended use of the elevator.

Overall, the key differences between freight elevators and passenger elevators lie in their size, weight capacity, controls, safety features, and compliance with building codes. Freight elevators are designed for heavy-duty use, while passenger elevators prioritize passenger comfort and convenience.
