Abstract
Steep-angle conveying installations may be used to transport raw materials along a slope of an open-cast mining pit, typically from a low-level loading station at a working level of the open-cast mining pit to a high-level unloading station at a ground level. The steep-angle conveying installation may comprise a track arranged on the slope of the open-cast mining pit, as well as one or more conveying cages for moving raw materials along the track between the various levels. Each conveying cage may include an emptying flap that is movable between an open position and a closed position. A thrust carriage may be employed outside the conveying cages to move the emptying flap of the conveying cages between the open and closed positions.

A steep-angle conveying installation for transporting raw materials along a slope of an open-cast mining pit from a low-level loading station at a working level of the open-cast mining pit to a high-level unloading station at a ground level, the steep-angle conveying installation comprising:
- a track arranged on the slope of the open-cast mining pit;
- a first conveying cage and a second conveying cage movable along the track between the low-level loading station and the high-level unloading station, the first and second conveying cages configured to receive raw materials, the first and second conveying cages each having an emptying flap articulatedly disposed on a base side of the conveying cages to permit emptying of the raw materials from the first and second conveying cages, the emptying flap being articulatedly movable between an open position and a closed position;
- and
- a thrust carriage for moving the emptying flap between the open position and the closed position, the thrust carriage positionable against the emptying flap from an outside of the first and second conveying cages by way of a movement that is independent of the movement of the first and second conveying cages.
A method of actuating an emptying flap articulatedly disposed on a base side of conveying cages of a steep-angle conveying installation for use along a slope of an open-cast mining pit, wherein the emptying flap is articulatedly movable between an open position and a closed position, wherein the conveying cages are for transporting raw materials from a low-level loading station at a working level of the open-cast mining pit to a high-level unloading station at a ground level, the method comprising:
- moving a conveying cage to the high-level unloading station;
- moving a thrust carriage against an outer side of the emptying flap;
- unlocking the emptying flap by way of a flap lock;
- and
- articulatedly moving the emptying flap by way of a controlled longitudinal movement of the thrust carriage while maintaining contact between the emptying flap and the thrust carriage, wherein the movement of the thrust carriage is independent of the movement of the conveying cage.
