A dolly for moving objects is disclosed, having a rectangular platform with casters mounted underneath, having four posts which may be raised from the base and locked into an upright position. The posts further have crossbars pivotally mounted thereon, which are releasably connectable to the crossbars of adjacent posts, to form a supportive railing around the tops of the posts. The posts may further be connected by means of telescopic arms, which are pivotally connected to one crossbar, and extendible to another crossbar, wherein they may be releasably connected by means of a knob at the end of the telescopic arm being pressed into an inverted teardrop-shaped receptacle. |
