A slab cart for sheet material which comprises a dolly component. A shelf component receives the sheet material. A mechanism is for coupling the shelf component to the dolly component in a pivotable manner, so that the shelf component will go from a horizontal position to a vertical position. When the shelf component is in the horizontal position the sheet material will be manually slid off of the shelf component onto a support table and be manually slid from the support table onto the shelf component. When the shelf component with the sheet material is in the vertical position, the sheet material will be held on edge to the shelf component and be transported by the dolly component through the confines of narrow places.

1. A slab cart for sheet material which comprises: a) a dolly component;b) a shelf component to receive the sheet material; andc) means for coupling said shelf component to said dolly component in a pivotable manner, to allow said shelf component to go from a horizontal position to a vertical position, wherein when said shelf component is in the horizontal position the sheet material can be manually slid off of said shelf component onto a support table and be manually slid from the support table onto the shelf component, wherein when said shelf component with the sheet material is in the vertical position, the sheet material can be held on edge to said shelf component and be transported by said dolly component through the confines of narrow places, wherein said dolly component comprises:d) a rectangular carriage frame;e) four casters rotatably mounted to underside of said rectangular carriage frame at each corner thereof;f) a pair of stanchions, wherein each said stanchion is pivotally mounted and height adjusted oppositely at a rear corner and a front corner of said rectangular carriage frame; andg) an upright member pivotally mounted and height adjusted at center of said rectangular carriage frame opposite from said stanchions, wherein said upright member retains said shelf component in the horizontal position, wherein said shelf component comprises:h) three flat U-shaped members, with each said flat U-shaped member having a forward hook end, a handle extending from said forward hook end and two flat legs extending rearwardly from said forward hook end; andi) a flat cross brace affixed to underside of said flat legs of said flat U-shaped members, wherein said coupling means comprises:j) a pair of short tubes, each said short tube affixed transversely to a top end of each said stanchion of said dolly component;k) a long tube affixed transversely to underside of said flat legs of said second flat U-shaped member, and said innermost leg of said first and third flat U-shaped members of said shelf component;l) a pair of stub tubes, each said stub tube affixed transversely to underside of said outermost flat leg of said first flat U-shaped member and said third flat U-shaped member of said shelf component, wherein said pair of stub tubes are in alignment with said long tube with a gap therebetween being of a length of said short tubes; andm) a pair of elongated shaft components, each said elongated shaft component is insertable through one said stub tube, one said short tube and into one side of said long tube, thereby allowing said shelf component to pivot thereabout. 2. A slab cart for sheet material which comprises: a) a dolly component, wherein said dolly component comprises: i) a rectangular carriage frame;ii) four casters rotatably mounted to underside of said rectangular carriage frame at each corner thereof;iii) a pair of stanchions, wherein each said stanchion is pivotally mounted and height adjusted oppositely at a rear corner and a front corner of said rectangular carriage frame; andiv) an upright member pivotally mounted and height adjusted at center of said rectangular carriage frame opposite from said stanchions, wherein said upright member retains said shelf component in the horizontal position;b) a shelf component to receive the sheet material, wherein said shelf component comprises: i) three flat U-shaped members, with each said flat U-shaped member having a forward hook end, a handle extending from said forward hook end and two flat legs extending rearwardly from said forward hook end; andii) a flat cross brace affixed to underside of said flat legs of said flat U-shaped members; andc) means for coupling said shelf component to said dolly component in a pivotable manner, to allow said shelf component to go from a horizontal position to a vertical position, wherein when said shelf component is in the horizontal position the sheet material can be manually slid off of said shelf component onto a support table and be manually slid from the support table onto the shelf component, wherein when said shelf component with the sheet material is in the vertical position, the sheet material can be held on edge to said shelf component and be transported by said dolly component through the confines of narrow places, wherein said coupling means comprises: i) a pair of short tubes, each said short tube affixed transversely to a top end of each said stanchion of said dolly component;ii) a long tube affixed transversely to underside of said flat legs of said second flat U-shaped member, and said innermost leg of said first and third flat U-shaped members of said shelf component;iii) a pair of stub tubes, each said stub tube affixed transversely to underside of said outermost flat leg of said first flat U-shaped member and said third flat U-shaped member of said shelf component, wherein said pair of stub tubes are in alignment with said long tube with a gap therebetween being of a length of said short tubes; andiv) a pair of elongated shaft components, each said elongated shaft component is insertable through one said stub tube, one said short tube and into one side of said long tube, thereby allowing said shelf component to pivot thereabout.
