No, ratchet straps should not be used for lifting because they are designed for securing and tying down loads, not for lifting them. Ratchet straps have a working load limit (WLL) that indicates the maximum weight they can safely secure without breaking. However, lifting requires specialized equipment designed to handle the weight and to ensure safety. Using ratchet straps for lifting can result in the strap breaking, the load falling, or other accidents. Always use appropriate lifting equipment such as hoists, cranes, and slings for lifting heavy loads.
