Abstract: A method of damping the oscillations during an emergency stop of an ascending single drum hoist system in a shaft having a conveyance, the mechanical brakes applying a braking force to the drum and the drum rotating in a first direction having a speed, comprising applying a first brake force when the drum speed reaches close to zero enabling the drum to roll back in an opposite direction to the first direction by a force generated from a first conveyance downward swing, and controlling the brake force during the first conveyance downward swing to dissipate the energy of the swing.
