METHOD AND UNIT FOR THE ACCURATE POSITIONING OF A LOAD RECEIVING PLATFORM AT A FIXED LOCATION FOR RECEIVING OR SENDING OUT LOADS

摘要

The platform (10) is provided on its lower face on the front side with two cone-shaped bore-holes (16) which, when lowering the platform, are engaged by two positioning pins (15) and which automatically center the platform. In order to facilitate the centering of the platform, the rear portion of the latter is mounted free on a spherical bearing (13).
