The transportation process covers the transportation of a load from Bay 1 to Bay 2 by the trolley and the returning of the trolley to Bay 1 from Bay 2 after it has been unloaded at Bay 2. Included are the system states involved in this process and the actions required to move the system from one state to the next. The transmission mechanism is described. This includes a description of the different system states and the transition between the states (state-transition diagram). Sketches of the actual physical set-up are provided showing how the different elements in the system interact. For example, the four pins used in the system are described and how they operate; and sketches are provided showing how they are connected to the trolley frame.
The critical activities occurring in the trolley during the transportation process are described. The operation of the springs is described with illustrations. And the way in which an operator interacts with the system is also described.
