Features And Specification Of Electric Vehicles:

In parts of the world which lack a high level of infrastructure, electric ambulances are designed to meet local conditions, being built using intermediate technology. Electric vehicles can also be trailers, which are pulled by bicycles, motorcycles, tractors, or animals. Animal-powered ambulances can be particularly useful in regions that are subject to flooding. Motorcycles fitted with sidecars (or motorcycle ambulances) are also used, though they are subject to some of the same limitations as more traditional over-the-road ambulances. The level of care provided by these electric ambulances varies between merely providing transport to a medical clinic to providing on-scene and continuing care during transport.
The design of intermediate technology must take into account not only the operation and maintenance of the ambulance, but its construction as well. The robustness of the design becomes more important, as does the nature of the skills required to properly operate the vehicle. Cost-effectiveness can be a high priority.
In addition to visual warnings, this type of vehicle can be fitted with audible warnings, sometimes known as sirens, which can alert people and vehicles to the presence of an ambulance before they can be seen. The first audible warnings were mechanical bells, mounted to either the front or roof of the ambulance. Most modern ambulances are now fitted with electronic sirens, producing a range of different noises which vehicle operators can use to attract more attention to themselves, particularly when proceeding through an intersection or in heavy traffic.
The speakers for modern sirens can be integral to the light-bar, or they may be hidden in or flush to the grill to reduce noise inside the electric vehicle that may interfere with patient care and radio communications. Ambulances can additionally be fitted with air-horn audible warnings to augment the effectiveness of the siren system.
