What is the maximum permitted inside height of a dumbwaiter car?

The maximum permitted inside height of a dumbwaiter car is 1,200 mm (48"). This measurement is established to ensure that dumbwaiters, which are smaller service elevators primarily used to transport goods, comply with safety and functionality standards. The 1,200 mm height allows for versatility in transporting various items without compromising on safety or operational efficiency.

By adhering to this height requirement, dumbwaiters can effectively serve their intended purpose while also ensuring that they do not pose risks related to the loading and unloading of goods. In many jurisdictions, building and safety codes are very specific about these dimensions to provide a consistent standard of safety and usability across different installations.
