Abstract: A suspension system for suspending a tool from a pair of parallel rails. The suspension system consists of a support structure, a tool mounting interface and exactly three trolley assemblies. The support structure has three trolley assembly mounting structures with a first one of the trolley assembly mounting structures positioned on a first side of the support structure and the remaining trolley assembly mounting structures are positioned on the opposite side. The tool mounting interface is adapted to couple the tool to the support structure. Each of the trolley assembly mounting structures is coupled to a trolley assembly. Each trolley assembly has at least one trolley set with a plurality of wheels adapted to roll on one of the parallel rails. The three trolley assemblies collectively adapted to exert a reaction force onto the pair of parallel rails equal to the weight of the suspension system and the tool.

Abstract: Disclosed is a polar crane supported by a rail and having a bridge and a bridge-supporting end truck at each end of the bridge. Each end truck has, for either direction of revolving bridge motion, a leading wheel contacting the rail. In the improvement, the leading wheel of each end truck has a single flange and the flange is inward of the rail. Skewed crane "lock-up" is thereby substantially prevented. A related method for modifying a polar crane includes raising the first end truck away from the rail, removing a two-flange wheel (the leading wheel) from the first end truck and installing a one-flange wheel in place thereof.

Abstract: A live storage facility provides for the storage of large containers of product in a gas-tight enclosure containing an atmosphere precisely controlled to a preselected gas composition. Containers are introduced into the enclosure through a tunnel and removed through another tunnel, without significantly altering the gas atmosphere or temperature within the enclosure. An externally controlled crane moves and stacks the containers within the enclosure. The storage facility is preferably formed as a hemispherical dome with continuous walls that are impermeable to the gas. In one form, the product is agricultural produce, and there is additionally provided a cooling capability so that the product is stored at reduced temperature.
