ABSTRACT:
The present invention provides a circulating rack having an electric drive which can be pivoted, to a limited degree, in opposed directions dependent upon the transmitted torque of the electric drive. The drive is mounted on a pivotal rocker element which is displaced against the force of two counteracting elastically deformable abutments. A torque transmitted by the electric drive to overcome non-uniform loading of the circulating rack system causes the pivotal rocker to be displaced in either a clockwise or counterclockwise direction. A displacement measuring sensor measures the extent of pivotal movement of the rocker to provide an indication of the non-uniform loading condition so that corrective action may be taken. If the rocker is pivoted beyond a predetermined range, as for example that caused by a severe overloading condition, the displacement measuring sensor will cause the electric drive to turn off and prevent further circulation of the system until the overload has been corrected.
