Gravity needs no specific "devices". ANY mass in the Universe attracts ANY other mass. So, the only thing you need for gravity to work, is to have two objects that have mass - so basically, any two objects.

Some devices that use electromagnetism to work include electric motors, generators, transformers, solenoids, and magnetic resonance imaging (MRI) machines.
A Machine is something that helps do work. Work, in mechanics, is the amount of energy output over a distance. A force is what does the work, so a force acting over a distance does work...which is what machines help do. Further, the amount of time that a force takes to do work will determine the POWER output.
Waterwheels, hydroelectric power plants, and falling weights are some examples of devices or systems that can be powered by gravity. Gravitational energy is harnessed to generate electricity or perform mechanical work in these cases.

Simple machines are devices that makes work easier- changing size, direction, speed of force

It means you work as an engineer for the USMC (United States Marine Core) or if you mean marines as in marine biology, then it means you will work on mechanical devices meant to be submerged in a 5hit load of water. War machines or water machines.
Devices like water clocks, barometers, and some types of scales depend on gravity to function properly. For example, a water clock relies on gravity to control the flow of water through a narrow opening, while a barometer uses gravity to measure air pressure. Scales rely on the force of gravity to accurately measure the weight of an object.
The term "gravity generator" seems to be used for different concepts. The first hits in Google are related to machines that purport to provide "free energy", in other words, a perpetuum mobile (perpetual motion machine). Such machines are not possible to build - there are good reasons to believe that the Law of Conservation of Energy is valid, in other words, you can't make energy out of nothing. You can see many such designs, and explanations of why they don't work, if you search the Internet for "the museum of unworkable devices".

Things that doesn't need lots of work on. Like washing machines, dishwashers, vacuum cleaners and so on.
