In general, presently existing dollies are rigid structures which are not particularly suitable for supporting filing cabinets or the like to render them mobile. A relatively simple, yet strong trolley or dolly includes generally U-shaped, sideways opening brackets which are connected, in perpendicular relationship, to each other and to downwardly opening, C-shaped lightweight channel sections to define a rectangular frame. At least one bracket at each corner of the frame carries a wheel for rendering the dolly mobile. |
