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.

Abstract: In a ladder tower having multiple telescoping sections, each section includes a pair of longitudinally extending, laterally spaced apart truss members and a plurality of longitudinally spaced ladder rungs interconnecting the truss members. Each truss member includes an upper elongated hand rail, a lower elongated rung rail being spaced below and lying in a common plane with the upper hand rail, and a plurality of braces extending between and interconnecting the upper hand rail and lower rung rail of each truss member. The ladder rungs of each section extend between and interconnect the rung rails of the truss members thereof. Pretensioning structure is connected to the hand rail of each truss member so as to load the hand rail in compression and the rung rail in tension and thereby substantially offset the dead load of each section due to its weight and permit an increase in the live load capacity of each section. Further, the hand rail of each truss member of each ladder tower section is hollow.

Abstract: An improved ladder supported rescue platform for use as an evacuation tool is disclosed. The platform includes a peripheral rail system wherein a gate can be raised vertically by a worker to enter the platform from the ladder or to enter the ladder from the platform. The geometry of the gate construction is designed to assure automatic closure without any action on the part of the user. The gate is designed of parallelogram configuration and may include a snaplock to secure the gate in its closed position.
