A wheel of a roller includes a roller axis, the wheel being driven by an electric motor, wherein the electric motor is a hub motor which drives a hub body, which extends with circumferential spacing and surrounds the wheel axle, relative to the fixed wheel axle, wherein furthermore the wheel has a running surface. The running surface is formed on a running surface carrier and the running surface carrier is supported flush on the hub body at the back of the running surface. Further, a manually movable load truck includes one or more rollers, of which at least one roller has a driven wheel. Further, an operating device, in particular for a manually movable load truck, is formed having a substantially annular cross-section having a central through opening.

1. A roller (5) comprising a wheel (31) that is driven by an electric motor and has a stationary wheel axle (6), wherein the electric motor is a hub motor (19) that drives a hub body (7) surrounding the stationary wheel axle (6) with circumferential spacing relative to the stationary wheel axle (6), andwherein the wheel (31) furthermore comprises a running surface (10), wherein the running surface (10) is on a running surface carrier (11) and the running surface carrier (11) is supported on the hub body (7) in a planar fashion on a rear side of the running surface (10),wherein further the running surface carrier (11) is pot shaped with a pot bottom (14) extending outside the hub body (7) and essentially perpendicular to the stationary wheel axle (6) and a pot wall overlapping a circumferential wall of the hub body, andwherein the hub body (7) comprises a pot shaped part that encompasses the circumferential wall (9) and a side wall (8), which side wall (8) is overlapped by the pot bottom (14),wherein the pot shaped part of the hub body (7) is encompassed with respect to a front edge of the pot wall by another pot shaped part and said another pot shaped part provides an other side wall (8) as pot bottom and an overlapping section (29) formed by the pot wall, andwherein one or more circumferential ribs (15) are formed on the running surface carrier (11) for dissipating heat. 2. The roller according to claim 1, wherein the running surface carrier (11) has said one or more circumferential ribs (15) that form part of an outer surface of the running surface carrier (11). 3. The roller according to claim 2, wherein said one or more circumferential ribs (15) is realized circumferentially. 4. The roller according to claim 1, wherein a roller fork (16) is provided, and wherein the roller fork (16) is made of a sheet metal part with a width corresponding to 10-times the thickness of the sheet metal part or more. 5. The roller according to claim 4, wherein the roller fork (16) is realized in a U-shaped fashion. 6. The roller according to claim 1, wherein a horizontally aligned enclosure part (18) vertically extends over part of height H of roller (5). 7. The roller according to claim 6, wherein the enclosure part (18) is made of a sheet metal part with a width corresponding to 10-times the thickness of the sheet metal part or more. 8. The roller according to claim 6, wherein the enclosure part (18) vertically extends only over part of the height H of the roller (5) or the roller fork (16). 9. A load truck (1) that can also be maneuvered manually and has at least one roller (4, 5), of which said at least one roller (5) has a driven wheel (31), comprising a design of the roller (5) according to claim 1. 10. The load truck according to claim 9, wherein said at least one roller (5) is controlled with respect to a power output of the electric motor. 11. The load truck according to claim 9, wherein a control device (25) is arranged on the load truck (1). 12. The load truck according to claim 9, wherein said at least one roller comprises two rollers (5) with respectively said driven wheel (31). 13. The load truck according to claim 9, wherein said at least one roller comprises two rollers (5) with said driven wheel (31) which is controlled independently of one another. 14. The roller according to claim 4, wherein the roller fork (16) is made of a sheet metal part with a width corresponding up to 200-times or 300-times the thickness of the sheet metal part. 15. The roller according to claim 7, wherein the enclosure part (18) is made of a sheet metal part with a width corresponding up to 200-times or 300-times the thickness of the sheet metal part.
