ABSTRACT:
An obstacle moving device for a caster wheel is made of an electrically insulating material and is of two identical halves. The device is assembled without moving, stabilizing or disassembling the caster wheel by placing the halves on opposite sides of the caster wheel and then securing them together. A pair of roller assemblies inside the device abut the caster wheel so that rolling motion of the caster wheel pushes the device across the floor. Any obstacle encountered by the device is pushed along the path of movement of the wheel.
