Displaceable inclined hoist
First Claim
1. A displaceable inclined hoist comprising:
- a displaceable support;
an inclined support pivotally mounted to said displaceable support for rotation about a horizontal axis and in a vertical plane;
drive means connected between said displaceable and inclined support for pivoting said inclined support on said displaceable support;
two pairs of tracks connected to said inclined support and extending therealong, said two pairs of tracks having different gauges and each having a middle portion and opposite end portions, said two pairs of tracks lying in a common plane at each of their opposite ends and being disposed one above the other in said middle portions, the upper one of said pair of tracks having a wider gauge than the lower one of said two pairs of tracks;
a conveyor car mounted for riding on each of said two pairs of tracks, said two pairs of tracks being spaced apart in said middle portions thereof by an amount sufficient to permit clearance for one of said conveyor cars riding on a lower one of said two pairs of tracks; and
windlass means connected to said conveyor cars and carried by said inclined support for moving said conveyor cars upwardly and downwardly on said two pairs of tracks respectively.

Abstract
A displaceable inclined hoist has conveyor cars which can be moved up and down along two tracks by cable lines driven by windlasses, where the tracks together with the windlasses are located on a support construction, which is mounted in the region of its upper end around a horizontal axle on a displaceable support structure. The support construction can be pivoted in the perpendicular plane with the aid of a drive where the pair of tracks, which have different track gauges, lie one above the other in their middle region and lie in one plane in their end regions. The pairs of tracks lying one above the other, together with the support construction, have a separation distance from each other which provides clearance for the passage of the conveyor cars.
