ABSTRACT:
A muck-evacuating system such as for use in tunneling operation and including in combination a train of wagons running in a tunnel and an elevator of separate receptacles adapted to automatically pick up the muck-filled receptacles one by one off the train of wagons, to raise them through a shaft to automatically trip them over to discharge the muck therefrom into a chute at ground level, and to return the emptied receptacles on the wagons, which are then moved through the tunnel for refilling at the tunnel face. The system includes a pair of laterally spaced-apart endless conveyor link chains defining an elevating conveyor run and a lowering conveyor run, a train of wagons, separate receptacles removable off the wagons, hooks secured to opposite sides of each receptacle, studs secured to the link chains and inwardly projecting to upwardly engage the hooks of the receptacles and thus elevate the latter, and a tripper member positioned and profiled to serially trip the receptacles to empty the same into the upper end of the shaft and allow return of the empty receptacles back onto the train.
