AMBULANCE |
|
An ambulance is a vehicle designated for the transport of sick or injured people. The first ambulances called by that name were horse ambulances used in the American Civil War. The first practical ambulances were created by Dominique Jean Larrey, a French surgeon (17661842), for use in the Napoleonic Wars. Modern-day ambulances are typically large automobiles on a van or light truck chassis.

An escalator is a conveyor transport device for transporting people, consisting of a staircase whose steps move up or down on tracks that keep the surfaces of the individual steps horizontal.
A moving walkway, moving sidewalk, travelator, or travellator is a slow conveyor belt that transports people horizontally or on an incline in a similar manner to an escalator. In both cases, riders can walk or stand. The walkways are often supplied in pairs, one for each direction.
