Abstract

In a storage installation, a load carrier drive for propelling a load carrier longitudinally in the aisles between storage frames includes a rotating coupling member driven by the drive for contacting and driving the drive of a transfer car when the load carrier is positioned for transfer by the transfer car, whereby the transfer car is propelled by the load carrier drive.

Dependent claims

A multivehicle arrangement comprising

a first vehicle including load handling means mounted thereon operative to transfer a load to and from said first vehicle,
a second vehicle supported for movement on a substantially horizontal surface for transporting said first vehicle over and parallel to said surface when said first vehicle has been positioned in a transport position on said second vehicle, said first vehicle also being movable on said surface when off of said second vehicle and movable in a given direction onto and off of said vehicle,
first drive means for propelling said first vehicle when said first vehicle is not in said transport position on said second vehicle, said first drive means including first support means for drivingly supporting said first vehicle for movement upon said surface,
second means for propelling said second vehicle, said second means for propelling including second support means for drivingly supporting said second vehicle for movement upon said surface,
first and second ends on said first vehicle, said ends being spaced from each other in said given direction of movement,
first and second elevation means adjacent said first and second ends of said first vehicle and mounted in spaced relation to each other on said first vehicle for elevating said first vehicle above said surface as said first vehicle is being propelled by said first drive means to move onto said second vehicle, third and fourth elevation means spacedly mounted on said second vehicle and operably engageable with a respective one of said first and second elevation means, said third elevation means including means engaged by at least a portion of said first support means as said first vehicle is moved onto said second vehicle and gravitational elevation assist means distinct from said first support means of said first vehicle and adjacent said first end of said first vehicle when said vehicle is in said transport position, said elevation assist means gravitationally assisting the elevation of said second end of the first vehicle by moving said first end of said first vehicle downwardly as said second end is moved upwardly on said fourth elevation means, and
power coupling means, also distinct from said first support means of said first vehicle, coupling said first and second vehicles together automatically in response to the action of said first elevation means and said gravitation assist means and when said first vehicle is in said transport position for transferring power from said first drive means to said second means for propelling said second vehicle.
