Abstract
A mobile work platform contains a base having two sections. The first section contains an energy source, a motor, a gearbox, a drive axle, and at least one drive wheel. The second section contains two steerable casters. The second section telescopes relative to the first section so that the distance between the drive axle and the controlled casters, and the length of the base, are variable. The platform also contains two ladders that are removably attached to the base and that and extend upward from the base, an upper horizontal working platform, and a control system for regulating the speed and direction of travel.
