Abstract
A dolly system with a motorized rolling track is disclosed. The dolly system includes a dolly having two generally vertically extending side rails. An L-shaped support is provided at its lower end thereof and a cross brace is provided adjacent to its upper end. A pair of rotatable wheels are located adjacent to the L-shaped member. Two pair of rearwardly facing braces are provided on the support rails. One pair of facing braces is adjacent the upper end thereof and one pair is adjacent the lower end thereof. An upper rotatable support rod is supported by the upper braces. A lower rotatable support rod is supported by the braces with a plurality of parallel idler rollers therebetween rotatably supported by a central block. The axis of rotation of the idler rollers is parallel with the axis of the rods. Drive cylinders are mounted on the rods with an endless belt positioned over the cylinders for rotation therewith, the belt being movable in a path of travel rearwardly of the support rods. A drive motor and operating drive belts couple the drive motor and the support rods to rotate the support rods and hence the belts upon activation of the motor.
