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
Elevator the ropes by the grip of the grooves in the sheave, thereby the name. As the ropes age and the traction grooves wear, some traction is lost and the ropes must be replaced and the sheave repaired or replaced. Sheave and rope wear may be significantly reduced by ensuring that all ropes have equal tension, thus sharing the load evenly. Rope tension equalization may be achieved using a rope tension gauge, and is a simple way to extend the lifetime of the sheaves and ropes. Elevators with more than of travel have a system called compensation. This is a separate
