Abstract

A carriage of a mobile storage system is adapted to support at least one storage unit for movement on a rail. The carriage generally includes a wheel mount structure, and a wheel mounting subassembly that includes a shaft having opposing ends, a wheel mounted to the shaft, and a first and a second mounting members that rotatably support the shaft. The wheel is located between the first and second mounting members such that the ends of the shaft extend outwardly from the first and second mounting members. The carriage further includes a cooperating mounting arrangement configured to non-rotatably mount the first and second mounting members to the wheel mount structure. The wheel extends downward from the wheel mount structure to engage the rail, and the ends of the shaft extend outward to engage a drive shaft that imparts rotation to the shaft and wheel so as to move the carriage on the rail.
