Abstract:
A stepladder comprises a front frame and a rear frame each formed of a pair of spaced side rails. A motor-driven step is slidably mounted on the front frame side rails. The motor is controlled with a remote unit allowing a worker to automatically raise and lower the step when accessing an elevated area.
