For freight elevators, the hoistway door to sill must be no more than what distance?

The correct distance for the hoistway door to sill for freight elevators is specified to be no more than 4 inches. This regulation is in place to ensure safety and ease of operation when freight is being loaded and unloaded. A maximum opening of 4 inches helps prevent small or narrow items from becoming wedged in the gap between the doors and the sill, which could pose a hazard. It also minimizes the risk of a person accidentally falling through a larger gap.

Maintaining this specific distance is crucial for the proper functioning of the elevator system and aligns with state code and safety standards. It helps ensure that the mechanisms involved in the elevator's operation function efficiently while providing a safe environment for the transportation of goods.
