Abstract
A mobile storage system is provided with safety devices that increase the stability of the movable carriages. The safety devices includes shoe plates mounted to the carriages proximate each carriage wheel and above the rails. A nylon shoe is attached to the bottom of each shoe plate near the rail. The shoe plates are adjustable to position the shoe with minimum running clearances with the rails. Only a small amount of initial tipping causes the shoes to contact the rails and support a carriage against further tipping. The increased spread between the anti tip shoes compared with the spread between the wheels provides increased resistance to overturning forces by the square of the ratio of the spreads.
