Braking Safety Conditions for Multi-Rope Friction Sheaves
Authors:
Abstract
In accordance with the current safety regulations, the braking torque for service and safety braking must be at least three times the static torque for lifting or lowering the design load. At the same time, the deceleration of the system during safety braking must be no less than 1.5 m/sec^2 when the design load is lowered and no more than 5 m/sec^2 when it is lifted. The last requirement is imposed by the Safety Rules to the systems with drum hoisting machines, but nowadays such norms are adhered to and with friction pulleys (MacNII, plant named after XV-anniversary of LKSMU and others).
