Abstract
A lifting apparatus and controller therefore, where the lifting apparatus includes independently driven lifting columns and independently driven wheels that are controlled by a controller having a number of sensors such as limit sensors, position sensors, rotation sensors, laser sensors, torque sensors and the like. The independent motors for lifting and driving may also be removed easily to provide for improved servicing and maintenance. The various sensor signals are used to calculate, coordinate and calibrate the apparatus for precise and safe movement by the motors in order to perform lifting and positioning operations, for example rail car repair and service.
