Ropeway guying, gyns are better than sheers for supporting a ropeway. Ropeway A ropeway is a form of naval lifting device used to transport light stores and equipment across rivers or ravines. It comprises a jackstay, slung between two sheers or gyns, one at either end, from which is suspended a block and tackle, that is free to travel along the rope and hauled back and forth by inhauls (ropes attached to the pulley from which the block and tackle are suspended).It is a very useful method of Transportation for very short distance. Because they are more stable, in particular in
Wire rope spooling technology its behaviour and affects lifespan. Fleet angle should be between 0.25° and 1.25°, depending on the rope construction. The fleet angle can be varied by moving the first sheave closer to or further away from the drum. If the sheave is too close to the drum, the fleet angle will be greater than 1.25°; if it is too far away, the fleet angle will be less than 0.25°. Sometimes it is not possible to achieve the optimum fleet angle. Where there is no space to rig a sheave the requisite distance from the drum, two additional spooling devices are available.
