1. A cart for transportation of electronic equipment through a data center, said cart being manually propelled and guided, comprising: a rectangular bed with a horizontal base and vertical walls on three sides, wherein the open side is a short side;two rectangular wheel plates attached one on either side of the bed to the top edges of the longer two of said vertical walls, said rectangular wheel plates being in a horizontal plane, two wheels being attached to the underside of each of said rectangular wheel plates, said rectangular wheel plates having the same length as said rectangular bed;a vertical skirt attached to said rectangular wheel plates around the outer edges of said rectangular wheel plates;a frame attached to said rectangular bed, wherein said frame includes four vertical struts attached one to each corner of said rectangular bed and three horizontal struts attached between said vertical struts at the top of said vertical struts, said three horizontal struts being positioned above said vertical walls of said rectangular bed; anda gate attached to said horizontal base at the open end of said rectangular bed by one or more hinges, said gate being securable in a vertical plane. 2. The cart of claim 1, further comprising restraints attached one to each of the two vertical struts of said frame at the opposite end of said rectangular bed to the open side of said rectangular bed and the position of attachment of said restraints on the vertical struts is distal to said rectangular bed. 3. The cart of claim 1, wherein each of said wheels is attached to the corresponding rectangular wheel plate by a swivel mount to allow for the wheel to rotate about a vertical axis passing through said swivel mount. 4. The cart of claim 1, wherein said cart is configured to provide a clearance of less than or equal to one inch between said horizontal base and the horizontal plane defined by the bottom of the wheels attached to said wheel plates. 5. The cart of claim 1, wherein said cart is configured to provide a clearance of less than or equal to half an inch between said horizontal base and the horizontal plane defined by the bottom of the wheels attached to said wheel plates. 6. The cart of claim 1, wherein said vertical skirt has one aperture adjacent to each of said wheels, each of said apertures being configured to allow for manual access to the corresponding wheel. 7. The cart of claim 1, wherein the four wheels are configured on said cart with one of the four wheels in close proximity to each of the four outer corners of said cart. 8. The cart of claim 1, wherein the height of the horizontal struts of said frame above the horizontal base of said rectangular bed is between 40 and 50 inches. 9. The cart of claim 1, wherein the horizontal base of said rectangular bed has a length of between 45 inches and 65 inches and a corresponding width of between 29 inches and 41 inches. 10. The cart of claim 1, further comprising two triangular brackets each attached between a different one of the two vertical struts adjacent to the open end of said rectangular bed and the top surface of the corresponding adjacent rectangular wheel plate. 11. The cart of claim 1, wherein said gate is securable in a vertical plane by gate restraints attached to the vertical struts of said frame at the open end of said rectangular bed and a gate bar which slides into the gap behind both gate restraints and in front of said gate. 12. The cart of claim 11, wherein said gate bar is configured to fit between said horizontal base of said rectangular bed and said gate when said gate is in a lowered position, said gate bar covering said hinges and being flush with said gate and said horizontal base. 13. The cart of claim 1, further comprising a winch bracket attached to the outer side of the short vertical wall of said rectangular bed and a winch securable in said bracket. 14. A method of manually transporting electronic equipment through a data center on a cart, comprising: loading electronic equipment onto said cart;after said loading, stabilizing said electronic equipment in said cart using a strap secured at restraints attached to said cart;after said stabilizing, manually maneuvering said cart across a substantially flat floor; andafter said manually maneuvering, unloading said cart; wherein said cart comprises:a rectangular bed with a horizontal base and vertical walls on three sides, wherein the open side is a short side;two rectangular wheel plates attached one on either side of the bed to the top edges of the longer two of said vertical walls, said rectangular wheel plates being in a horizontal plane, two wheels being attached to the underside of each of said rectangular wheel plates, said rectangular wheel plates having the same length as said rectangular bed;a vertical skirt attached to said rectangular wheel plates around the edges of said rectangular wheel plates not attached to said vertical walls of said rectangular bed;a frame attached to said rectangular bed, wherein said frame includes four vertical struts attached one to each corner of said rectangular bed and three horizontal struts attached between said vertical struts at the top of said vertical struts, said three horizontal struts being positioned above said vertical walls of said rectangular bed, and the restraints attached one to each of the two vertical struts of said frame at the opposite end of said rectangular bed to the open side of said rectangular bed and the position of attachment of said restraints on the vertical struts is distal to said rectangular bed; anda gate attached to said horizontal base at the open end of said rectangular bed by one or more hinges, said gate being securable in a vertical plane;wherein the height of the horizontal struts of said frame above the horizontal base of said rectangular bed is between 40 and 50 inches. 15. The method of claim 14, wherein said electronic equipment is a server rack. 16. The method of claim 14, wherein said electronic equipment exceeds 40 inches in height. 17. The method of claim 14, further comprising manually maneuvering said cart across a height transition in the floor level, said height transition being less than half an inch. 18. The method of claim 14, wherein said loading includes attaching a first strap around said electronic equipment, attaching a winch strap to said first strap and manually winching said equipment into said cart, wherein said cart further comprises a winch bracket attached to the outer side of the short vertical wall of said rectangular bed and a winch secured in said bracket. 19. The method of claim 14, further comprising, both before said loading, lowering said gate to the floor and placing a bar between said horizontal base of said rectangular bed and said gate, said gate bar covering said hinges and being flush with said gate and said horizontal base. 20. The method of claim 19, further comprising, after said loading, raising said gate into a vertical position and securing said gate by sliding said bar in front of said gate and into the gaps behind gate restraints attached to the vertical struts of said frame at the open end of said rectangular bed.
