• In gearless elevators, the motor turns a gear train that rotates the sheave. Roped elevators are much more efficient than hydraulic elevators, they also have more safety systems. 1.1.3 Elevator safety mechanism The first elevators in use were not especially safe because once in a while a cable would break, The design phase should produce detailed class diagrams, collaboration diagrams, sequence diagrams, state diagrams, and activity diagram. However, the elevator problem is too simple for an activity diagram. Thus, we are not using an activity diagram for the elevator problem. Sequence Diagram. A sequence diagram and collaboration diagram conveys ... diagrams that illustrate the functional requirements of the elevator controller. Some of the types of diagrams that are used here include, sequence diagrams, state diagrams, and collaboration diagrams. There is also a part of this section that describes the interface between the controller and the rest of the elevator system as a set of signals.
