Side mounted air supply for wheel lift independent of vehicle air brake
Apparatus and associated methods relate to a vehicle having independent fluid reservoirs for a fluid-activated brake system and at least one auxiliary fluid consumer. In an illustrative example, a first reservoir may be mounted above a chassis and outboard of a vehicle such that longitudinal axes of the reservoir and the vehicle are substantially aligned. The first reservoir may, for example, be fluidly coupled to a fluidly activated brake configured to brake at least one wheel on at least one axle of the vehicle and fluidly coupled to the first reservoir. At least one second reservoir may be fluidly coupled to at least one auxiliary fluid consumer of the vehicle such that the first reservoir is fluidly independent from the at least one second reservoir and the at least one auxiliary fluid consumer. Various embodiments may advantageously provide stable air supply for critical braking functions of the vehicle.
