Abstract
Abstract In a storage installation, an electrical connector couples the controller of the load carrier to the transfer car drive means and the controller on the load carrier operates the load carrier drive motor and also the transfer car drive motor, the latter being operated when the load carrier is positioned for transport by the transfer car and the connectors are coupled. The load carrier is elevated above the storage installation floor during transport by way of a downwardly inclined ramp which minimizes the elevation power requirements.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
143 words
In a multivehicle arrangement including a first vehicle and a second vehicle adapted to transport the first vehicle, comprising first and second drive means for propelling said first and second vehicles respectively, extending from said power source to said second vehicle and connecting power transmission means a source of power spaced from said vehicles, said first drive means to said source of power to propel said first vehicle relative to said second vehicle, power coupling means mounted on said vehicles coupling said first and second vehicles together automatically when said first vehicle is positioned for transport by said second vehicle, and switching means cooperating with said power coupling means for transferring power from said first drive means through said coupling means to said second drive means for propelling said second vehicle when said first vehicle is positioned for transport on said second vehicle.
Claim 2
Dependent Claim
143 words
In a multivehicle arrangement including a first vehicle and a second vehicle adapted to transport the first vehicle, comprising first and second drive means for propelling said first and second vehicles respectively, extending from said power source to said second vehicle and connecting power transmission means a source of power spaced from said vehicles, said first drive means to said source of power to propel said first vehicle relative to said second vehicle, power coupling means mounted on said vehicles coupling said first and second vehicles together automatically when said first vehicle is positioned for transport by said second vehicle, and switching means cooperating with said power coupling means for transferring power from said first drive means through said coupling means to said second drive means for propelling said second vehicle when said first vehicle is positioned for transport on said second vehicle.
Claim 3
Dependent Claim
21 words
