ESCO Pulleys
A pulley is a tool that moves a rope or chain by wrapping it around a disk-shaped sheave and rotating it. It is used to expand power, change direction and transmit power, etc. It is also used to lift heavy objects and as a rope guide when using a winch. There are fixed pulleys with fixed axes, moving pulleys that are not fixed and can move up and down, and double pulleys that use a combination of the two. A snatch block, in which part of the side plate frame opens, is used when attaching wires with processed tips, etc., because it allows ropes to be easily attached and detached. In addition, there is a block type where the frame is fixed and the rope passes through from the end. Upper part shapes include hook, eye and shackle. Because strength differs between types due to structural differences, it is necessary to check the application and working load before selecting.
