Abstract
A fire fighting vehicle provides the capability to access obstructed areas, to quickly connect to fire water sources, to discharge large amounts of water and/or foam to fight major industrial fires, and to be capable of repositioning while fighting these fires. The vehicle is adapted from a boom truck chassis and mounts a large flow rate capability fire monitor in a position to provide maximum orientation flexibility.
Claims12
A fire-fighting apparatus comprising:
- a chassis;
- means for discharging a fire-fighting fluid towards a fire;
- a coupling connected to said means for discharging said fire-fighting fluid;
- a transducer signalling a coupling status of said coupling;
- and
- a brake interlock on said chassis wherein said transducer signalling actuates said brake interlock when said coupling is coupled.
3 more elements
A fire-fighting apparatus comprising:
- a chassis;
- a fire monitor having a nozzle, said fire monitor swivel-mounted on said chassis;
- a fire hose coupling fluidly connected to said fire monitor;
- a transducer signalling a coupling status of said coupling;
- and
- a brake interlock on said chassis wherein said transducer signalling actuates said brake interlock.
3 more elements
A fire-fighting apparatus comprising:
- a chassis;
- a fire monitor having a nozzle, said fire monitor swivel-mounted on said chassis so that no portion of said fire monitor is higher than about 3 meters off a ground surface;
- a fire hose coupling fluidly connected to said fire monitor, wherein said coupling comprises a plurality of parallel connected couplings attachable to a plurality of fire hoses connected to a source of fluid supply and each of said parallel connected couplings is a quick disconnect type having a nominal diameter of at least about 10 cm;
- at least two pairs of wheels supporting said chassis off said ground surface, wherein both of said pairs of wheels are steerable and at least one wheel of both of said pairs of wheels is motor driven and said steerable wheels are coupled and controlled by a single operator;
- a transducer signalling a coupling status of at least one of said parallel connected couplings;
- and
- a brake interlock on said chassis, wherein said transducer signalling actuates said brake interlock.
