<p>An electrical power supply arrangement for a guidable stock selector truck for use in low temperature (e.g. -10 DEG F) environments having a storage cart, operator platform, enclosure walls, and heating members. The power arrangement comprises a generally longitudinally elongated guide rail spaced in close proximity to a floor surface and laterally spaced from storage racks by a distance sufficient to accommodate longitudinally extending bus bars surrounded by an insulated guide member and a protected pivotal electrical contactor device connected to the truck having contact birds adapted for continuously engaging and transferring the electrical energy from the bus bars to the truck. Inclined converging lead-ins positioned at ends of the bus bars serve to direct the contact birds to respective contact channel surfaces defined by respective bus bars before the contact birds enter respective contact channels. In a preferred embodiment, the selector truck is provided with an enclosed working area for the platform and within which the heating members allow a selector to be in a more comfortable working temperature.</p> |
