What is the purpose of a single pulley?
The role of the pulley is to pull the load, change the direction of force, and transmit power.
A outdoor pulley is a small wheel with grooves around the circumference that can rotate around an axis. A simple machine that can rotate around the central axis, consisting of a grooved disc that can rotate around a central axis and a flexible cable (rope, tape, wire rope, chain, etc.) that spans the disc, is called a pulley.
The pulley introduced today is a single pulley, mainly in two basic colors, red and yellow. It is suitable for outdoor rock climbing, slow descent, high-altitude outdoor work, and outdoor practice activities. Its maximum tensile force is 30KN, which is safe and reliable, and is widely used in outdoor rock climbing activities.
