ABSTRACT:
In accordance with one embodiment of the present invention, the mobile lift system includes a 3 ft..times.3 ft. rack and pinion platform lift providing a cage able to lift at least one man and gear up a pole of a billboard sign or any advertising sign and to detach the platform from the rack so access can be achieved at many different pole/rack sites with a single platform lift. The mobile hoist or lift is practical because it eliminates ladders from tall poles and provides safer route access. This will save time for the worker because his harness has been eliminated and the hardship of climbing the ladders has also been eliminated. Another point of interest will be the saved money and reduced liability because the ladders have been removed so that unauthorized individuals cannot climb up the poles. Mobilizing the lift saves money in material cost and maintenance because there may be one platform for 150 racks (poles) or more. Another advantage over prior art is that there are no pins to insert or bolts to install when attaching or detaching the lift from the rack sites.
