Definitions
- the present invention relates to fire fighting vehicles.
- the invention is particularly directed to, but not limited to, fire-fighting vehicles of the type commonly used in areas outside main city centres.
- the invention is also concerned with a modular pump unit, body module and other equipment for use with fire fighting appliances.
- Modern fire appliances include a pumping unit for connection to a source of water in order to deliver relatively large volumes of water in fighting a fire.
- the pumping unit may have its own power source but usually is mechanically driven by coupling of the pump unit to the drive shaft of the appliance that extends from the appliance transmission to the rear wheels.
- the pumping arrangement of the appliance also incorporates the means for producing a fire fighting foam, which is used to suppress the fire.
- the urban pumper conventionally has a pump unit located to rear of the chassis of the appliance which supplies water/foam to a fire hose supported on a rotatable cylindrical reel supported on the pump unit.
- the pump unit requires periodic maintenance. Because pump units are usually relatively large, heavy assemblies, service and maintenance of the unit can be difficult and expensive. Most importantly, servicing of the pumping unit of the appliance may take days if not weeks during which time the appliance is not available for fire fighting purposes. Moreover in the event of the pump unit requiring more major repair, the appliance may have to be taken out of service for several weeks. During high-risk fire periods in country areas, there is a need to have as many fire fighting appliances available in case of a major forest or scrub fire. Therefore, a pump system that minimises or even eliminates the need to take the fire fighting appliance out of the field for service, maintenance or repair, would be highly advantageous.
- the present invention seeks to address, at least in part, the appliance down-time involved in servicing, maintaining and/or repairing the pump unit of conventional fire appliances.
- the present invention provides a fire fighting appliance or the like for over-the-road travel the appliance including: a wheeled support structure and laterally spaced chassis rails; a mechanically driven pump module located between the chassis rails, the chassis rails including mounting means for said pump module for sliding engagement of corresponding mounting means on the pump module, the respective mounting means allowing sliding movement of the pump module relative to the chassis rails to permit the pump module to slide out to the rear of the appliance to permit access to the pump module for repair, servicing and/or maintenance; and releasable securing means for securing said pump module in an operative condition.
- the pump module may incorporate a pump and primer, delivery and suction manifolds.
- the pump of the pump module is mechanically driven by the engine of the fire fighting appliance or the like, via a power take-off from the engine of the appliance.
- the pump drive shaft may be decoupled from the power take-off to allow the pump module to slide out to the rear of the vehicle.
- the pump unit has a drive shaft that is mechanically driven by coupling the pump unit to a split shaft power take-off from the vehicle, when the pump module is an operative position on the vehicle.
- the module preferably includes an electric rewind hose reel and pump panel incorporating all the controls for operating the pump.
- the pump module of the invention may also incorporate provision to carry a spare wheel of the appliance.
- chassis mounting means and the pump module mounting means are such as to allow the pump module to slide out from within the body and be removed from the appliance in the event of the pump module requiring major servicing or repair. The removed pump module may then be replaced by simply sliding in a replacement pump module.
- the pump module rolls on roller bearings inside the chassis rails. It will be clear to the reader that other means for providing sliding engagement may be used, for example, roller wheels. Moreover the chassis support mounting means does not necessarily have to be located inside the channel rails.
- the removable securing means may be any means that secures the pump module to the chassis to prevent the pump module sliding relative to the chassis when the pump module is in its operative mode.
- the securing means can be removed to allow the module to slide out from the chassis as described above.
- the removable securing means may be bolts that bolt the pump means to the chassis rails when maintenance is not required. Other forms of securing means will be evident to those skilled in the art.
- the invention in its first aspect provides a system that reduces appliance downtime during maintenance, servicing or repair of the pump unit, thus maximising the availability of fire fighting appliances in the field.
- the present invention in a second aspect, provides a pump module for a fire fighting appliance having lateral chassis rails or the like, the pump module including mounting means adapted to co-operate with corresponding mounting means on the chassis of the fire fighting appliance to provide sliding engagement between the pump module and the chassis rails of the fire fighting appliance.
- the present invention also provides an improvement in a body component of a fire fighting appliance.
- the present invention provides a body module for a fire fighting appliance, the body module having opposed sides and opposed front and rear ends, the body having a low centre of gravity and a low profile tank and incorporating at least one storage means on each of the sides and at least one storage means located at rear end of the module.
- the body module being formed at least in part from a fibreglass material.
- the body module may be formed at least in part from aluminium.
- the exterior of the body module is finished in a gelcoat finish to provide a long lasting durable external coating.
- the rear end of the body module is configured with two flanked hose lockers and two suction hose lockers incorporated into the upper section of the body module.
- the body module is easily removable from the appliance chassis and is located on the chassis of the appliance by a plurality of rubberised mounts.
- the present invention provides a wheeled fire appliance vehicle for over-the-road travel, the fire fighting appliance having fixed to the body thereof a body module in accordance with the present invention in its third aspect.
- a further improvement provided by the present invention relates to the cabin steps of the fire fighting vehicle.
- the present provides a cabin step for use with a over-the-road vehicle fire fighting appliance, the cabin step including a tread plate to provide a non-slip surface and further including a toe guard to prevent a foot sliding through the step and wherein each step is progressively staggered out to provide good visibility whilst accessing the cabin.
- the step may include slide out storage means for storage of a battery or the like.
- the storage means may be a battery box.
- the cabin steps include one or more handrails.
- the handrail(s) include safety warning indicia thereon to provide improved egress and access from the cabin.
- the warning indicia may be a safety yellow coating.
- the present invention provides an over-the-road fire fighting appliance, the appliance including the present invention in its first to fifth aspect.
- Figs, la and lb are rearward views of a fire fighting appliance incorporating an embodiment of a pump module in accordance with the invention in its retracted position;
- Fig. 2 is a section side view of the fire fighting appliance shown in Figure 1 with the pump module of Fig.l in its extended position;
- Fig. 3 is a top view of the pump frame bolting location
- Figs. 4a and 4b are off-side rear view and a near-side front view respectively of an embodiment of a body module in accordance with the invention; and Figs. 5a, 5b and 5c are photographs showing an embodiment of cabin steps in accordance with the present invention.
