New Head Rope Replacement Technique of Mine Frictional Hoist and Application

A new head rope replacement technique was introduced for the mine frictional hoist.A special U type fastener would be applied to fasten the used and ne w ropes together.With the winch in operation, the used rope could drive the new rope down to the mine shaft bottom.With the hydraulic rope adjustment device and the f ast rope locker on the mine shaft headframe, the used rope would be replaced by the new rope and then the used and new rope replacement could be conducted with t he reversed operation of the hoist.This method could highly reduce the application of large temporary facilities and the safety risks of the operations in the mine shaft a nd could reduce the construction time. This method could provide the related references to the head rope replacement of the mine hoist.
