VEHICLE MOUNTED FIRE AND RESCUE BOOM

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.
