Abstract
The ladder stand employs a pair of swivable caster wheels at the front and a pair at the rear which are used in cooperation with a pair of closely located non-swivable caster wheels, thereby providing a structure which has three modes of operation, one mode for climbing, a second mode which permits the stand to be pushed in a straight line with wide turns and a third mode of operation which permits the stand to be first pushed laterally and to provide sharp turns. A front wheel support is mounted on the front end and a retractable first pair of swivable caster wheels is mounted on the front support. A rear wheel support is mounted on the rear end, with a retractable second pair of swivable caster wheels mounted on the rear support. A third pair of non-swivable rigid caster wheels are mounted at the rear end.
