A building hoist can be used for lifting both large and small objects, depending on its design and capacity. These hoists are engineered to handle various weights, typically ranging from a few hundred pounds to several tons. The specific size and weight of the objects that can be lifted are determined by the hoist's lifting capacity, which is a crucial factor to consider when selecting a hoist for a particular job. It's important to ensure that the hoist's capacity exceeds the weight of the objects to be lifted for safety and efficiency.
