[7:1 Lifting Rate] This pulley system provides an 8x mechanical advantage, allowing you to lift heavy loads with approximately 1/8th of the effort. For example, lifting a motorcycle would require only about 70 pounds of force. [Reinforcement Design] Reinforced side design helps prevent the block and tackle system from twisting and side-bending during use. [4 x Pulleys] This block and tackle pulley system uses a 3/8-inch rope and offers greater durability and load capacity compared to a triple pulley setup. It has a breaking strength of 4,400 lbs (2T), suitable for towing most household vehicles. [65 Ft Rope] Includes 65 feet of 3/8-inch rope. When used with the quadruple pulley configuration, the maximum working distance is 8 feet, sufficient for most overhead lifting tasks. [Wide Applications] Ideal for hunting, boating, marine use, garage projects, deer hoisting, tree trimming, DIY attic storage, and other heavy-duty applications.
