Claims7
A deck for a cage in a materials handling system which includes a pair of rails for a tracked vehicle, the rails extending in a first direction, a plurality of rollers located between and outside the rails, the upper surface of the rollers being at least as high as the upper surfaces of the rails, the rollers being rotatable about axes which are transverse to the first direction, drive means for rotating at least some of the rollers in a selected sense of rotation, and at least one cover which is pivotally mounted and which is movable between an upright position at which the rails, and the rollers, are exposed, and a horizontal position in which it forms a load-bearing platform which overlies at least some of the rollers.
A deck for use with a cage structure comprising:
- underlying support adapted to be secured to the cage;
- a plurality of rails fixedly mounted with respect to said underlying support and extending in a first direction, said rails being adapted for supporting a track vehicle;
- a plurality of rollers located between and outside said rails, the upper surface of said rollers being at least as high as the upper surface of said rails, said rollers being rotatable about axes which are transverse to said first direction;
- drive means for rotating at least some of said rollers in a selected rotational direction;
- and,
- at least one cover which is pivotally mounted and which is movable between an upright position, at which the rails and the rollers are exposed, and a horizontal position in which it forms a load-bearing platform which overlies at least some of the rollers.
A structure for a materials handling system comprising:
- a cage structure having support walls extending in a vertical direction;
- and, at least one deck structure positionable between said support walls and adapted to be fixed at a location along said support walls so as to extend in a direction transverse to the direction of said support walls, said at least one deck structure including:
- an underlying support, adapted to be secured to said cage walls;
- a plurality of rails fixedly mounted with respect to said underlying support and extending in a first direction, said rails being adapted for supporting a tracked vehicle;
- a plurality of rollers located between and outside said rails, the upper surface of said rollers being at least as high as the upper surface of said rails, said rollers being rotatable about axes which are transverse to the first direction;
- drive means for rotating at least some of the rollers in a selected rotational direction;
- and, at least one cover which is pivotally mounted and which is movable between an upright position at which the rails, and the rollers, are exposed, and a horizontal position in which it forms a load-bearing platform which overlies at least some of the rollers.
