Using a building hoist in windy weather is generally not recommended due to the increased risk of accidents. Wind can cause the hoist to sway, potentially leading to loss of control and dropping of the load. Safety guidelines typically advise against hoisting operations when wind speeds exceed certain limits, often around 20-30 miles per hour (32-48 kilometers per hour). It's crucial to check local regulations and the manufacturer's guidelines for the specific hoist model to determine safe operating conditions. Always prioritize safety and ensure that all necessary precautions are taken to secure the load and the hoist in windy conditions.
