A ratchet strap is a type of fastening device used to secure loads during transportation. It consists of a high-tensile webbing strap and a ratchet mechanism, which is a handle and a set of gears that allow the strap to be tightened incrementally. The webbing strap is made from durable synthetic fibers, such as polyester, which provide strength and resistance to abrasion and weather conditions. The ratchet mechanism enables the user to apply significant tension to the strap, ensuring that the load remains securely in place. Ratchet straps are commonly used in various industries, including trucking, shipping, and construction, to prevent cargo from shifting or falling during transit. They are favored for their reliability, ease of use, and ability to handle heavy loads.
