Rope drive careful fireproofing from the loom floors. It was sometimes arranged for large drives that the engine drove a set of horizontal ropes to a pulley on a layshaft or 'second motion shaft' alongside the engine house, then diagonally up through the shaft. Rope drive A rope drive is a form of belt drive, used for mechanical power transmission. Rope drives use a number of circular section ropes, rather than a single flat or vee belt. The first multiple rope drive was a 9 rope drive of 200 bhp produced by Combe Barbour for their Falls Foundry, Belfast, in 1863. James
Block and tackle tackle the direction of the pulling force is reversed though the mechanical advantage remains the same, Diagram 3a. This is an example of the Luff tackle. The decision of which to use depends on pragmatic considerations for the total ergonomics of working with a particular situation. Reeving to advantage is the most efficient use of equipment and resources. For example, if the load is to be hauled parallel to the ground, reeving to advantage enables the pulling force to be in the direction of the load movement, allowing obstacles to be managed more easily. Reeving to disadvantage adds an extra
