Abstract
A rack and pinion elevator system having at least two spaced racks and an elevator cage therebetween which carries at least one drive motor in driving engagement with each rack respectively, includes a transmission device such as a shaft which is connected to the elevator cage. At least two pinions, each engaging with a respective rack, are rigidly secured to the transmission means so that the pinions move along the racks together with the elevator cage to transfer driving forces via the transmission device from the less loaded to the more loaded side of the elevator cage thereby to substantially equalize the loads on the separate drive motors regardless of the position of the center of gravity of the load in the elevator cage.
