Ladder Cart / Cart

Cart and ladder are necessarily used in a complicated working area or a factory. Normally, this ladder is not easy to move because of its long length and is even uncomfortable to keep. Also, people can be injured by the rugged topography, narrow entrance and long length, when it to the inside or the outside of the factory. This design is transformable into a ladder from a hand cart, is practical and portable, and is appropriate for the rough and rugged factory.
