Yes, a building hoist can be used for lifting objects that are too large to fit through a doorway. Building hoists are designed to handle heavy and oversized items, lifting them vertically through small openings or directly from the ground to higher floors. They are particularly useful in construction projects where large materials or equipment need to be moved to upper levels of a building. However, it's important to ensure the hoist is properly installed and operated by trained personnel to maintain safety and avoid damage to the building or the items being lifted.
