A correlator system for automatic car wash has roller assemblies for supporting the front left and right wheels of a vehicle entering a car wash line. A set of guide rails or bars cooperate with the roller assemblies to adjust axial displacement and angular misalignment between the vehicle's front end and a conveyor track transporting the vehicle through the car wash facility. The rollers in the roller assembly rotate freely with minimal friction, axially displacing the front end of the vehicle and adjusting the angular misalignment of the front wheels. The low friction, easy-to-rotate rollers are provided with a plurality of braking elements that generate friction against the rollers, retarding their rotation when a worker steps thereon. The friction generated by the braking elements is insufficient to prevent roller rotation during alignment of the front end with the conveyor track. Injuries to car wash personnel caused by loss of balance when stepping on the rollers are virtually eliminated, and an accurate alignment of the vehicle's front end with the car wash conveyor track is reliably achieved.

A generally horizontally disposed, laterally extendable pin car-engaging assembly is mounted on the car-moving carriage for aligning with and engaging a hook loop on a railcar for moving the car. A gate-operating assembly which includes a laterally extendable chuck system which aligns with, engages and rotates gate-operating capstans on bottom discharging railcars may also be provided.

A personal lift device is disclosed having a motor having an output shaft. A gearing system is operatively connected to the output shaft for increasing torque.
