The dolly as defined in claim 1 wherein the transverse cross section of each wheel as viewed through the point at which the wheel engages the floor or underlying surface is arcuate in shape. 3. The dolly as defined in claim 1 wherein the shape of the transverse cross section of each wheel as viewed through the point at which the wheel engages the floor or underlying surface resembles a U. 4. The dolly as defined in claim 1 wherein each wheel of the two sets of wheels are arranged for rotation about axes which are parallel to one another and include two opposite side faces, and the chassis assembly includes a first elongated skirt within which the wheels of one of the two sets of wheels are rotatably mounted and a second elongated skirt within which the wheels of the other of the two sets of wheels are mounted, and each of the first and second elongated skirts includes one face-covering portion which extends along one of the two side faces of the wheels in the corresponding set of wheels and another face-covering portion which extends the other of the two side faces of the wheels in the corresponding set of wheels. 5. The dolly as defined in claim 1 wherein the number of wheels of each set of wheels is four. 6. The dolly as defined in claim 1 wherein the frame includes cross member assemblies which extend between the two opposite side rails of the frame, and the cross member assemblies accommodate an adjustment in the spaced-apart distance between the two opposite side rails of the frame and the side-to-side width of the load-supporting platform. 7. The dolly as defined in claim 6 wherein the cross member assemblies of the frame include one cross-member which is arranged adjacent the forward edge of the platform and includes two opposite ends which are disposed adjacent the two opposite side rails of the frame, and the cross member assemblies include another cross-member which is arranged adjacent the rear edge of the platform and includes two opposite ends which are disposed adjacent the two opposite side rails of the frame, and each of the one and another cross-members accommodates an adjustment in length between its opposite ends to thereby accommodate an adjustment in the spaced-apart distance between the two opposite side rails of the frame. 8. The dolly as defined in claim 7 wherein each of the one and another cross-members includes a first elongated member which provides one of the two opposite ends of the cross-member and includes a second elongated member which provides the other of the two opposite ends of the cross-member, and the first and second elongated members of each cross-member are releasably securable to one another in alternative lengthwise positional relationships to accommodate an alteration in the spaced distance between the opposite ends of the cross-member. 9. The dolly as defined in claim 8 further including means for releasably locking the first and second elongated members of each cross-member in a fixed positional relationship with respect to one another. 10. A dolly for transporting a load across a floor or underlying support structure, the dolly comprising: a chassis assembly providing an elongated load-supporting platform upon which a load is positionable and including a forward edge and an opposite rearward edge, and the chassis assembly includes a frame including two opposite side rails which extend between the forward edge and the rearward edge of the platform, and the platform has a fore-to-aft length as measured between the forward edge and the rearward edge thereof; andfloor-engaging wheels joined to the frame and are arranged beneath the load-supporting platform of the chassis assembly, the floor-engaging wheels including a first set of inline wheels disposed adjacent one of the two opposite side rails of the frame and a second set of inline wheels disposed adjacent the other of the two opposite side rails of the frame, the wheels of each of the first and second set of wheels including a forwardmost wheel and a rearwardmost wheel and least one intermediate wheel disposed between the forwardmost and rearwardmost wheels, and each of the first and second set of wheels has a front-to-rear length as measured between the front of the forwardmost wheel and the rear of the rearwardmost wheel, and each of the first and second set of wheels is substantially centered between the forward and rearward edges of the platform and the front-to-rear length of each of the first and second sets of wheels is about one-half of the fore-to-aft length of the platform so that an appreciable portion of the platform extends forwardly of the front of the forwardmost wheel to the forward edge of the platform and so that an appreciable portion of the platform extends rearwardly of the rear of the rearwardmost wheel to the rearward edge of the platform; andeach wheel of the first and second set of wheels has a peripheral surface for engaging the floor or underlying surface as the dolly is rolled therealong, and the peripheral surface of each wheel has a transverse cross sectional shape so that as the dolly is rolled across a floor or underlying surface, each wheel of the first and second set of wheels makes contact with the floor or underlying surface at substantially a single point to enhance the maneuverability of the dolly as the dolly is rolled across the floor or underlying surface. 11. The dolly as defined in claim 10 wherein the transverse cross section of the peripheral surface of each wheel is arcuate in shape. 12. The dolly as defined in claim 10 wherein the transverse cross section of the peripheral surface of each wheel is substantially U-shaped. 13.

The dolly as defined in claim 10 wherein the number of wheels of each set of wheels is four. 15. The dolly as defined in claim 10 wherein the frame is adjustable in width so that the spaced-apart distance between the two opposite side rails of the frame can be altered to thereby adjust the width of the load-supporting platform of the chassis assembly. 16. The dolly as defined in claim 15 wherein the frame includes at least one cross member assembly which extends between the two opposite side rails of the frame, and the at least one cross member assembly includes elongated members which can be telescopically shifted lengthwise with respect to one another to alter the spaced-apart distance between the two opposite side rails of the frame. 17. The dolly as defined in claim 16 further comprising means for releasably locking the elongated members of the at least one cross member assembly in a fixed lengthwise positional relationship with respect to one another to thereby fix the width of the load-supporting platform of the chassis assembly.
