Abstract
A pump module for a fire truck includes a self-supporting frame structure of rigid frame members with pump mounting beams laterally spaced in accordance with the spacement of the truck chassis rails. The beams are located generally centrally of the frame structure, which fits with an open truck body chamber with the beams aligned with the rails. The beams include a pump mount plates to which the pump is physically attached. The chassis rails are provided with longitudinally spaced mounting plates secured to the sidewalls of the rails and the pump beams and have similarly spaced mounting plates. The plates are connected by vibration isolation mount units each of which includes a t-shaped rubber mount interposed between the mount plates with a head portion therebetween and a stem portion projecting through the chassis plate. Clamping bolts extend through rubber mount and the mount plate brackets, and compress the rubber mount to establish vibrating isolation of the module and thereby the pump. Enclosing side walls on the module including access openings, have pump connectors, control and monitory instrument displays and control elements. The pump module has an upper chamber overlying the pump unit frame for containing monitoring and control elements, pump hoses and like elements. The sidewalls of the module include access panels for access to the pump control and the module mounting units.
