The rope and pulley system of an extension ladder is used to raise and lower the extendable (fly) section of the ladder. By pulling the rope, the user can easily move the fly section up or down to the desired height without having to manually lift the ladder section itself. The pulley at the top of the base section guides the rope, allowing the fly section to slide smoothly and be positioned securely
. This system reduces the effort required to adjust the ladder's height and improves safety by enabling controlled extension and retraction. The pulley mechanism also helps prevent the rope from slipping off or becoming jammed, ensuring smooth operation when the ladder is extended or retracted
. In summary, the rope and pulley on an extension ladder perform the action of raising and lowering the extendable section to adjust the ladder height efficiently and safely.
