Analysis of Reasons for Reduced Strength of Multiply Conveyor Belt Splices

Belt conveyors are used for the transportation of bulk materials in a number different branches industry, especially mining and power industries or shipping ports. The main component belt conveyor is its belt, which serves both as support transported material along route an element drive transmission system. Being crucial to effective reliable operation conveyor, also most expensive least durable element.
