Abstract: A pin handling device for coupling and decoupling conveyor segments to and from a train of conveyor segments in high wall mining includes a base frame, a base frame drive system for moving the base frame relative to the conveyor segments, a connector element for holding pins to be handled, a rotational drive system attached to the base frame and connected to the connector element, and a lift system attached to the base frame and carrying the connector element for linear movement of the connector element. A coupling pin is also provided for coupling conveyor segments in a train of conveyor segments in high wall mining as well as the conveyor segment that enables the use of such pin handling device and such coupling pins. A method of coupling and detaching conveyor segments for high wall mining is also provided.
