The cost of buying and installing a building hoist can vary significantly depending on several factors. The type and capacity of the hoist, the height of the building, and the complexity of the installation are key determinants. On average, the cost can range from $10,000 to $50,000 for the hoist itself, with installation costs potentially adding another 20-50% to the total. However, for very tall buildings or specialized hoists, the price can exceed $100,000. It's crucial to obtain quotes from multiple suppliers and installers to get an accurate estimate for your specific project.
