These can serve as both a primary set of tools or as a redundant system alongside gasoline-powered hydraulic tools.Įlectric tool systems have three general parts: power generation, transmission and tool. They have limitations on cutting and prying for heavier metal construction.Įlectrical power has been used with vehicle extrication tools first through power cords linked to electricity generators and more recently through batteries.They are limited to available air supply.There are a wide variety of appliances.These factors can be affected by friction loss in the hoses. This is the amount of air the tool uses to work the speed of the air is expressed as feet per second. Pneumatic tools weigh less than hydraulic tools, are very portable and have many excellent applications.Īir tools, with the exception of air bags, are often measured in not only in operating pressure but also cubic feet per minute. Whizzer saws and air chisels are examples of pneumatic-powered tools. Pneumatic rescue tools are powered by pressurized air from SCBA cylinders, vehicle-mounted cascade systems or vehicle-mounted air compressors. Gasoline-powered models create noise pollution on scene.It relies on caustic hydraulic fluid for operation.
