120 this pump imparts pressure to telescopic arms 121 which will raise shovels 112 since the flanges of such shovels pass between the laths 103 see fig2 the vehicle will be raised to the position of fig2 c once the vehicle is in the position of fig2 c the path of travel of extendible arm 119 will be reversed and thus the vehicle passes to the position of fig2 d that is to say into the cargo hoist unit 105 the cargo hoist unit will immediately descend see fig1 carrying the vehicle on one of its floors meanwhile one of the towers 122 in fig1 will have been displaced until it is situated next to the cargo hoist unit so that once such cargo hoist unit 105 is in line with one of the free floors of the tower 122 the cycle represented in fig2 a 23d will be repeated although in a reverse sequence that is to say from the position of fig2 d wherein the vehicle is inside the cargo hoist unit 105 to the position of fig2 a wherein the vehicle is outside the cargo hoist unit in the position of fig2 a wherein the vehicle is already deposited.
