Abstract
A mobile lifting apparatus has a platform coupled to elongated lifting arms arranged in a crossed configuration with a hinge at center portions of the lifting arms which allows the lifting arms to rotate in a crossed scissor manner when the platform is raised or lowered. The lower ends of the lift arms are coupled to automatic guided vehicles which move towards each other to raise the platform and move away from each other to lower the platform. A locking mechanism coupled to the lifting arms is actuated to prevent movement of the lifting arms to lock the height of the platform.
