摘要： An aerial ladder roller assembly to improve the function of the ladder during extension and retraction of sections of a multiple-section aerial ladder. One embodiment has a plurality of aligned apertures for rotatably mounting and a roller that is rotatably mounted in a housing. The housing has a roller pad and an aperture through which a roller extends. The housing is adapted for pivotal mounting at a point approximately central to the length of the axis. A roller is rotatably mounted in the housing on each side of the pivotal mounting point. A pair of rollers is rotatably mounted in the housing on each side of the pivotal mounting point. Also provided is a multiple-section ladder, having at least two nested sections with a housing having at least one roller is rotatably and pivotally mounted extending through an aperture. The slide plate of the second section juxtaposes the roller assembly.

摘要： A boom adapted for use on a fire fighting vehicle or a rescue vehicle includes an elongated boom having an outer housing. A second, inner body, forming an enclosed channel for water flow is contained within the outer housing. A plurality of connecting fins (for example, four) connect the interior of the outer housing with the exterior of the inner body, the space between the exterior of the inner body and the interior of the outer housing being divided by the fins into several generally independent channels within which elongated electrical control line members and hydraulic lines can be contained and protected. The boom may end at a workhead. The workhead may include a water monitor, water handline connections, a bank of lights, hydraulic fittings, pneumatic fittings, a lifting point and/or other emergency or rescue equipment. The boom may be pivotally mounted to a fire fighting vehicle such as a pumper engine, for example, on a turntable. The boom may include an extendible lift arm assembly and an intermediate lifting system.

摘要： A cradle assembly for aerial ladders (or booms) includes an assembly for rotatably and pivotally supporting an aerial ladder or boom, a first pair of upwardly extending parallel support flanges and a second pair of upwardly extending parallel support flanges extending upwardly from the surface of said turntable, the second pair of flanges extending to a substantially lesser elevation than said first pair of flanges; a cradle formed by a pair of parallel cradle arms laterally spaced to support a base end of said ladder or boom therebetween and at least one cross member connecting said arms, each of said arms having an end pivotally connected to a flange of said first pair of flanges; a hydraulic cylinder pivotally (which may be dual acting) attached to each of said cradle arms at a point spaced away from said first pair of flanges and an extendable-retractable rod projecting from each hydraulic cylinder and having an outer end pivotally attached to a flange of said second pair of flanges.
